First and most importantly, let me send out a big Happy Valentine’s Day wish to all of you. I hope that you and those you love treat yourselves to an extra special Valentine’s Day Sunday. Christine and I have done our best to do the same though our Valentine Möbius seemed to get the majority of the TLC and attention as you’ll see below.
Before I begin this week’s Progress Update, a brief story (I promise!) that sums up our lives right now.
When I was about 8 years old, my never ending curiosity lead me to read about one of Zeno’s paradoxes that completely dumbfounded me and led to many sleepless nights trying to wrap my head around it. That paradox has been haunting me again as we get closer and closer to finishing and launching XPM78-01 Möbius so I thought you might enjoy the story. I suspect many of you know this particular paradox often referred to as Zeno’s Paradox of the Tortoise and Achilles and you too might have also found it undeniably true but equally hard to accept at first. My eight year old self read it as a simple question;
If you want to get from Point A to Point B and each step you take is exactly 1/2 the distance between you and Point B, how many steps will it take you to get there?
An infinite number of steps and you will never get all the way there! Think about it, you’ll see the paradox.
Ahhh, I see those smiles and nods of recognition and you already know why I feel like I am living that paradox every day! Step after step, progress being made as we inch closer and closer but it feels like we’ll never get there. We WILL of course and you can read all about various “solutions” or different takes on this paradox but it does nicely sum up how Christine and I are feeling at this point.
More to the point that YOU care about and why you are reading, let’s jump into this week’s Show & Tell of the many half steps that Team Möbius DID make this past week of Feb. 8-13, 2021 and did move us closer to the finish line. And my apologies in advance for likely rushing you through this week’s Show & Tell, but it has been a very long week and it is now late Sunday evening as I’m typing this up and my vivacious Valentine awaits as does our dinner so I hope you will pardon the rush job this week.
Silicone based Foul Release Bottom Paint
If you were not able to catch up to last week’s Progress Update post “The Captain & Mr. Gee get CRANKY!” it may help to go read that over before continuing as we picked up where we left off last week wtih the preparation for the application of the International InterSleek 1100SR Foul Release paint that will cover all the underwater aluminium surfaces and keep them clean and slick by not allowing any marine growth to stick.
By the end of last week, we left the bottom paint crew having finished applying all the coats of International Epoxy Primer to the freshly sanded bare AL hull surfaces and masking off the 100mm / 4” wide glossy Black Boot Strip that makes the transition between the top of the Black InterSleek and the bare aluminium hull sides above the WL.
With the top and bottom edges of this Boot Stripe all taped off with Blue Painter’s Tape, they did a quick sand of the areas that would be sprayed with the glossy Black International Perfection polyurethane paint.
It was just before 18:30 quitting time when they got to the quick and easy part of spraying on several coats of the Black Boot Stripe. It is getting lighter here as the days get longer but still needed the help of an LED work lamp to do the spraying.
They let that dry for 24 hours and then masked it off for the big job coming next; applying the InterSleek 737 “Pink” primer coats and then the Black InterSleek final coats.
For the application of the InterSleek primer and topcoats, Naval called in the Big Guns from neighboring industrial boat builder Damen as they have a whole team of people who do nothing but InterSleek on the bottoms of the many big ships that they build and launch each year.
Given its thick consistency, InterSleek requires the use of airless spray equipment so they wheeled this bad boy over under Möbius and we brought out all the cans of InterSleek 737 Pink which is a three part A+B+C mix.
Ilyas is the Manager of Damen’s InterSleek team and started mixing this 3 part mix of 737 primer.
As per its name, an airless sprayer does not use compressed air to atomize liquid finishes out the end of a spray gun. Instead it uses hydraulic principles to push liquid paint directly from a big intake pipe set into the can of 737 Pink you see here and then out a spray gun nozzle at the other end. That big black round cylinder at the top of the airless sprayer seen here wrapped in protective plastic, is a giant rubber diaphragm that pumps up and down and pumps the liquid paint out the thing black hose you can see exiting the photo on the far Right edge by the blue pail.
This is the actual spray gun at the other end of that black hose where the highly pressurized paint flows out the small nozzle on the upper Right and ……..
…….. onto the hull like this.
As a former Automotive and Autobody teacher and antique car/motorcycle restorer, I have done my fair share of traditional spray painting but this airless spraying is more like using a very well controlled fire hose!
Möbius is 24m / 78 feet long on each side and yet
…. it took Ilyas less than 15 minutes to spray on two thick coats on all that area!
And that included details such as the Rudder and prop shaft Skeg, and …..
…… the Bow Thruster Tunnel.
The 737 Pink primer was allowed to set up for 24 hours and then it was time for …….
…….. the final 3 topcoats of the Black silicone based InterSleek 1100 SR which is also a 3 part mix. All mixed up and ready to be hydraulically pumped to that big spray gun in Ilyas’ hand.
While Ilyas suited up his team mates were busy rolling the Black InterSleek 1100 on all the edges of things like the Rudder and CPP Prop Skeg.
Depth and sonar transducers……
….. and deep up inside all the 5 Sea Chest tubes.
InterSleek 1100SR all mixed up and suction pipe set inside so it is all systems GO!
Difficult to capture with the camera amongst all the fumes but that gun blasts out a cone of paint that is about 1m / 39” wide
And so once again Ilyas had the first coats of Black InterSleek all sprayed on in under 15 minutes!
It is a fascinating product which looks very wet even when it is fully dry 24 hours later and to the touch it feels “sticky” and it remains that way throughout its 5-8 year expected life. You know this feeling if you have ever handled soft silicone cooking mats or the like as that is just what is now covering all of Möbius’ bottom. Go ahead and try to stick to that you little marine munchkins!
A second coat was applied the next day and once that had dried it was time to reposition all the support stands so that the area underneath them could also receive the full silicone InterSleek treatment.
Uğur was masterful at this tricky task as he positioned a new steel stand to one side of the existing ones and then hammered in new wood wedges to take up the weight of the boat enough to remove the wedges on the other stand and take it out.
And you can see what I mean about this InterSleek stuff being slick!
With the old wedges and stand out of the way we reveal these bare AL patches whose turn it is now to get the full epoxy primer and InterSleek treatment.
These patches are carefully taped off with some special “super tape” that can manage to stick to silicone and then a roller can be used to apply the epoxy primer coats like this.
Once the epoxy primer coats were fully dry, the 737 Pink silicone primer was rolled on next.
BTW, you can see that special tape quite well here.
Finally, the last 2 coats of Black InterSleek are rolled on and our bottom is done!
The Black discs you see like this one are 25mm / 1” thick AL mounting pads with a blind threaded hole where a circular Zinc anode will eventually be attached before launch.
This is how the very aft end of the hull will look for its underwater portion.
Painting the Nogva CPP Propeller
We got mixed reviews and recommendations for using the same InterSleek 1100SR to keep the CPP propeller equally as clean and slick as the rest of the hull so we opted to go with a single purpose silicone paint propeller paint called “PellerClean” which the Japanese company SeaJet created. If you would like to know more about this product and how to apply it, Matt over on the “MJ Sailing” YouTube channel that he and Jessica maintain so well, has THIS full video on their application of PellerClean on their prop last year. If you are not already subscribed to Matt and Jessica’s MJ Sailing channel we can recommend it highly as it is one of our many favorites for great boat related content.
This propeller treatment wasn’t covered by our agreement with Naval Yachts so Christine and I looked after this application. Do I really need to answer the question about why I am so madly in love with my Valentine and perfect partner for my very imperfect self?!?
The application of these very specialized silicone paint systems is very exacting so we followed them to the letter and prepped all the bronze with a 80 grit wheel to give the upcoming PellerClean Primer a good bit of “bite”.
The 2 part yellow coloured PellerClean comes in premeasured cans which you simply stir together well for about 5 minutes and then brush on.
It is very thick with a consistency similar to mayonnaise so it is a bit challenging to get all the brush marks out in the first coat.
But with each of the successive 3 coats we were able to get it well evenly applied and then let dry for 24 hours.
The clear topcoats go on next and curiously these are a single part product and after my experience with it I suspect it is pretty much pure silicone.
Another late night at the yard for us so this is all shot in the dark with just the LED work lights which really skew the phot colors so it looks very greenish here whereas the real colour is closer to a bronzy yellow but the more important part is that this is goes on smooth and slick!
I finished the 2nd coat of clear PellerClean yesterday and I’ll see what it looks like in the morning and decide whether to add a final 3rd coat.
It was not cheap but a clean propeller and bottom makes SUCH a difference in terms of boat speed and amount of power it takes to propel the boat through the water. This was very evident to us on our previous 52 foot sailboat and so now with our XPM power boat, these super slick easy to keep clean surfaces will make a huge difference in our fuel economy and increase our speed through the water. Stay tuned for those data points once we launch and start logging real world measurements.
More “Big Little Jobs” this past week:
Apologies in advance again for blasting through this but thought you would enjoy seeing some of the “little jobs” that add up to Big things which got done this past week.
Our Super Sewer Sinan, whipped up this “skirt” that wraps around the round Anchor Chain Bin and seals the top to the Hawse Pipe where the Chain comes In/Out and keeps all the muck and mud from the anchor chain, inside the Chain Bin where it is easily rinsed out through the drain in the bottom.
I had originally thought about having Sinan put in a clear plastic window so we could see inside the Chain Bin to see how the chain was moving In/Out but instead we went with this KISSS Velcro slit which you can open up anytime and peer inside.
Sinan attached the Skirt to the outside of the top of the Chain Bin with snap fasteners so it is also quick and easy to do the Full Monty and take the whole skirt off (but you can keep your hat on!)
The cylindrical tops of these Tiller Rudder Stops were back from the machine shop with their M16 threads for the SS bolt and locking nut that provide adjustment so Uğur was able to finish welding these up and we will show you them being mounted next week.
Ramazan was busy much of this past week up in the Master Cabin and here is is fitting the FastMount fasteners for the access panel below the seat in the Master Shower. This provides full access for all the plumbing and water manifolds hidden away inside the base of the Shower Seat.
Which the Captain is particularly looking forward to and testing out here.
Just outside the Shower, Ramazan has now installed the mirrors on this cabinet above the Vanity Sink at the very forward end of the Master Cabin.
As well as these mirrors on the doors of the cabinets above the sink inside the Master Head/Bathroom.
Overhead dropped ceiling above our bed is reflected in the mirror here so you may need to look twice to figure out that this is the full length mirror that Ramazan is mounting to the inside of the Shower/Head door now laying on top of the bed.
From the outside looking in I find Ramzan up at the Main Helm taping off the Rosewood Window Sills as he installs all 21 of the HVAC air vents on all the SuperSalon windows.
We were able to track down these very well made rotating adjustable air diffusers that are made for use in many different makes of cars and trucks and are the Goldilocks solution for bringing the hot or cold air from our AC/Heating system into the SuperSalon.
Same as the ones you would be familiar with in your car, these rotate and can be closed shut as in the photo above or tilted open at different angles. This will give us full adjustment to the air coming in to direct it into the room or up onto the windows for some defroster like function.
The largest front and center window in front of the Main Helm gets 3 of these vents.
And all the other windows have 2 diffusers.
Captain Christine has jumped feet first into the deep end of the electronics systems on Möbius and had a very busy week working with things like our PepWave cellular/WiFi router which I will cover in another post focussed on all of our electronics.
We had just enough of this gorgeous Turkish Turquoise marble from our inside Galley to use in our Outdoor Galley countertops as well and that all got mounted this past week.
We didn’t have quite enough to do all the countertops in single slabs but we are SO in love with this marble that we created the tops out of several pieces.
The system I came up with started with 6mm AL plates that are through bolted to the Vent Boxes underneath and then the marble is permanently adhered to these AL plates with industrial SikaFlex.
This allows me to remove the whole countertop for future access by unbolting these AL plates and provided a super solid backing for all the marble pieces.
First slab with the cut-out for the SS sink all glued in and ready for the 2nd piece.
To be set into the SikaFlex much like how you would lay ceramic tiles.
This will give you a sense of how our Outside Galley is shaping up and next week the marble team will be in to finish sealing and polishing the tops and edges. I can smell the salmon cooking on the BBQ already!
Möbius Goes to the Dogs!
Saving a bit of the best for the last, our two dogs, 14 year old Ruby the Wonderdog in Black and 9 year old Barney The Yorkshire Terror were onboard for the first time with Captain Christine so they could check out what will soon be their new floating home too.
Like us, they have both spent most of their lives as boat dogs and so are awaiting the move onto their new boat/home as anxiously as we are.
Barney is a rather “excitable boy” who can sometimes get a wee bit too excited at the edges of our boats so the bottom Dyneema lifeline that Christine now has all finished is at a custom “Barney height” so he got to measure up to that.
And down in the Master Cabin we have what we refer to as The Barney Bed, where Mr. Actionallnightlong, will be able to sleep and practice is nightly training for the Olympics all by himself!
And THAT folks is going to have to be a wrap for tonight as I am Wayyyyyyyyy past my time limit and bedtime and dinner still awaits.
Thanks SO much for taking the time to join us here again this week and just because it is taking me much longer than I would like to answer them, PLEASE keep adding your questions and comments in the “Join the Discussion” box below.
See you here again next week as we take yet another of our infinite half steps forward.
Not as much progress as we would have wanted to report this week as many of Team Möbius were MIA working on other boats at Naval Yachts and also prepping one of the boats beside us for its Owner’s visit tomorrow.
However, that didn’t stop the rest of us from making good progress and we achieved several big milestones that we are very eXcited to share with you now. So get a good beverage and comfy chair of your choice and come along for this week’s Möbius.World Show & Tell.
The Captain & Mr. Gee Get Cranky!
Several years ago, when I was answering some of Christine’s typically probing questions about why Mr. Gee our Gardner 6LXB was the Goldilocks Just Right, Just for us Choice for the main (and only) engine in XPM78-01 Möbius, Christine likes to say “You had me at Hand Cranked”.
This is in reference to me mentioning that one of the Gardner’s many eXtremely appealing features is that they could be fitted with this Chain Hand Crank option.
As you can see, this kind of “crankiness” makes my Captain eXtremely happy which makes me eXXtremely happy!
Very KISSS Keep It Simple Smart Safe as you can see with a rod running along the top of of the engine with handles at both ends with an Upper Chainwheel that transfers the crank’s rotation via a Chain down to a Lower Chainwheel keyed onto the engines crankshaft.
Michael and his team at Gardner Marine Diesel or GMD in Canterbury England were able to salvage all these parts off one of the many 6LXB’s they have in their inventory and sent them to me many months ago and I’ve been working on fitting them to Mr. Gee ever since.
You would think it would be a relatively quick and simple process to just clean and paint all these parts and install them on Mr. Gee …………………… but you’d be wrong!
One problem was that Mr. Gee is one of the later models of 6LXB and it had this quite different Hand Crank with just one handle on the front of the engine and a different crankshaft and Chainwheel setup down on the new style crankshaft.
Secondly, as you can see in this shot of the front support and Upper Chainwheel I’ve mounted onto Mr. Gee, there is no room up front for the Hand Crank handle, let alone enough room for me to get in there to crank it. So I needed to come up with a “Hybrid” Hand Crank setup that would allow me to marry the Old style with the Hand Crank Handle at the rear, to the new crankshaft end up front.
And just to put a particularly sharp point on this challenge, I also needed to drive the Jabsco Sea Water pump and one of our monster 250 Amp @24V Electrodyne alternators off the front of the crankshaft as well.
Let’s just say that the front of Mr. Gee became a very busy and challenging spot for me to sort out.
When I am doing this kind of problem solving and exploration of new design ideas I have evolved to using pieces of stiff cardboard I cut up from shipping boxes to capture the critical dimensions and sketch out my rough ideas.
It is a surprisingly efficient system as I get to reuse the many cardboard boxes all our hundreds of shipments come in and the stiffness of the cardboard makes is very easy to sketch on when I’m laying under or over an engine for example with my digital Vernier calipers or tape measure in hand and recording all the critical dimensions.
I then use Microsoft Office Lens utility on my Pixel4XL phone to digitize these sketches so I have a more permanent digital copy to keep and one I can print out if needed.
I don’t expect these to make much sense to anyone else but they work eXtremely well for me to record all these details and dimensions as I work my way through the different ways I come up with to solve a particular problem, create 3D models of them and ultimately machine or fabricate the parts I need and finally get them installed.
After much head scratching and sketching, eventually this layout emerged as a way that I could fit both the RED Chain based Hand Crank system and the GREEN cogged timing belt system for driving the Electrodyne “Big Red #1” in the upper Right here and the Jabsco sea water pump on the far Left.
I will show you the Green cogged timing belt drive system next week and show you the Red chain based Hand Crank system now.
With all the dimensions and my ideas roughed out on cardboard I then move over to Autodesk Fusion 360 to create a 3D model of all these parts where I can put my ideas to the test and see if they will actually work out. This is a quick screen grab of the model I came up with from the sketches you saw above.
I won’t bore you with all the details but for orientation Mr. Gee is mostly off the screen on the far Right and the Red disk is the Lower Chainwheel on Mr. Gee’s Crankshaft running horizontally across the bottom of the screen. On the front side of this is the cogged pulley driving the rubber timing belt that goes up to the cogged wheel on the Jabsco sea water pump.
* Note: I didn’t bother to model the actual chain and sprocket teeth so you will have to imagine that being wrapped around the Red Chainwheel.
The Green and Blue disks on either side of the Red Chainwheel are two of several flanged parts I needed to machine for my Hybrid Old/New Gardner Hand Crank system.
Oh, and did I mention that the Old Gardner Hand Crank system used a different pitch of chain than the New style?
So I had GMD send me the Upper and Lower Chainwheels from the New style that would fit nicely on the New style of Crankshaft that Mr. Gee has but the third Idler Chainwheel (part #37 in the Gardner illustration up above) had to the the Old style Chain as it is part of the cast aluminium bracket that supports the Old style cranking shaft.
FYI: Eventually I will design and machine a whole new Idler Chainwheel with the New style Chain pitch but for now I just mounted the Old Idler in my drill press and hand milled the teeth to get the New Chain to fit as you see here.
This is that Blue coloured Flange I pointed out AL in the rendering of the 3D Fusion 360 model above, which was quit easy to machine on a lathe out of solid aluminium round stock and then broach the keyway through the inner hole so it will be locked into the 3/8 x 3/8” key on the front end of the Crankshaft.
Now you can see how this newly machined AL Flange slides into the New style Lower Chainwheel which is now all sand blasted clean and painted Black.
All well and good but I’m sure that most of you are now asking “How the heck does this work to turn Mr. Gee’s Crankshaft Wayne?
That’s the job of the eXtra part you see here that rotates on a pin sticking out of the Chainwheel. This little part is the key to making the Hand Crank work and is called a “Ratcheting Pawl” part #3 in the Gardner Illustration above.
I don’t have a milling machine (yet!), but to badly reuse The Treasure of the Sierra Madre, (for those of you old enough to remember) “We don’t need no stinkin’ milling machine” right?
Nothing that a bit of ingenuity and my handy dandy 45 year old drill press and shiny new vice can’t handle. I machined a short shaft to just fit inside the hole of AL bushing and tightened that in the vice jaws.
This allowed me to slowly rotate the AL bushing into the 4 flute spiral milling cutter in my drill press so I could mill away the four recesses for the Pawl to fit into and ended up looking like this.
So to Hand Crank Mr. Gee you simply reach down and rotate the Pawl counter clockwise so it engages in one of the four recesses like this.
Now when Christine turns that Hand Crank Handle on the Aft end of Mr. Gee as you see her doing in the opening photo, the Upper Chainwheel rotates the Chain CCW, which transfers that force down to the Lower Chainwheel which the Pawl has now locked to the Crankshaft and around goes Mr. Gee!
This takes a good bit of muscle but with the compression relief levers keeping the intake valves open it isn’t too difficult to bring Mr. Gee’s massive flywheel up to speed and then you flip the compression levers back off and Mr. Gee chugs to life and begins to purrrrrr. Doesn’t get too much more KISSS or reliable than that!
Oh, and for those of you following all this, as Mr. Gee starts up you no longer need to turn the Hand Crank Handle and so the Pawl “ratchets” out of the recess back to this disengaged position such that the Chainwheel is now stationary while the AL Flange and Crankshaft spin together.
To finish putting this all together, I machined a groove into the AL bushing for this spring steel circlip to fit into which keeps the Chainwheel aligned and spinning on the AL bushing.
With the Lower Chainwheel assembled onto its new AL Flange, into the Engine Room I go and with a bit of TefGel 45 to help it slides just perfectly onto the keyed portion of the front end of the Crankshaft.
That modified Idler Chainwheel is in the upper Right here and it adjusts sideways in the slot you can see to the right of the Chain which you tighten down to keep the Chain Just Right Tight.
Not much space in here so a bit difficult to photograph but hopefully you can now see how the whole Chain driven Hand Crank system works.
And to come full circle, you now understand what put that great grin on my Beautiful Bride and Captain.
While we were cranking away on Mr. Gee, Hilmi and Ramazan were cranking away up in the SuperSalon so let’s go see what they have been up to this past week.
Ramazan has finished installing all the Ado LVT vinyl plank flooring and you may recall that Uğur, Nihat and I installed these two SS locking lift handles in the large hatch to access the Basement that is under the whole of the SuperSalon floor.
Most of Ramazan’s masterfully laid down flooring is covered in protective cardboard but you can see how nicely he has fit the edges around the hatch so they are barely visible.
But what’s that I see over on the far Left here?
Aha! Our 50” Samsung 4K SmarTV has arrived and will soon be mounted on a fully adjustable mounting system that fits into the recess in the now opened hinged and slotted Rosewood door.
But who’s that hiding behind that door?
Of course! Hilmi and Christine are busy finishing up all the wiring for AC, DC, Ethernet and N2K that runs inside the large space behind the TV.
This is also where our Boat Computer #1 will reside and Christine is anxious to start connecting it up and getting all our display screens up and running next week.
While she waits for Hilmi to finish the wiring behind the 50” TV, Christine fired up Boat Computer #2 and started setting things up in the SkyBridge Helm Station.
In the midst of all this, Sinan was back this week to start sewing up the Sunbrella covers like this one for that Upper Helm Station. He is also making a similar cover for the Upper Helm Chair and I will show you that next week.
Not a lot of progress on the Bottom Paint this week but they did get started on the 100mm / 4” Black Boot Stripe that makes the transition between the bare aluminium hull sides and the InterSleek 1100SR silicone Foul Release bottom paint which I have marked off for the painters here.
The International Epoxy primer has now been on longer than the maximum recoat time so they needed to do a light sanding so that the International Perfection Polyurethane paint will adhere well.
The laser level makes is SO must faster and easier to mark out perfectly straight and level lines for the masking tape to follow.
Next week the paint crew will hopefully be on site to spray on the Black Boot Stripe and then once it is dry they can mask it off and start applying the InterSleek Foul Release Bottom Paint. Hope to be able to show you all that next week as well.
All Donations Gratefully Received!
Why is THAT truck parking beside Möbius??
Yup! I’ve saved two of our bigger milestones for the end of this week’s Show & Tell. That’s a diesel fuel truck and Cihan is about to bring the very first drops of diesel fuel into our six integral fuel tanks!
It took a lot of time but I think we came up with an eXtremely effective design for both the Fuel Fills and Vents on Möbius.
With the fully sealed lid removed you have ready access to these three Fill Pipes on the Starboard/Right side and a matching set on the Port/Left side. These each connect to one of the six integral fuel tanks at the bottom of the hull with 40mm / 1 5/8” ID rubber fuel hose.
Just forward of the Fuel Fills, these inverted 40mm U pipes are similarly connected by that same size rubber fuel hose to the vents on each fuel tank. Together these both worked just perfect on this first fueling test with no foaming or “spit back”.
But mistakes can and will happen so we designed these Fuel Fill stations to have a large capacity spill tanks below the Fill Pipes so that any diesel that does overflow will simply run into this spill tank and drain back into the fuel tank. No mess, no fuss, no bother.
When the Fuel Fill cover is in place it completely seals off all the Fill Tubes from the outside air and from any sea water on decks. The Fuel Vent pipes have this slotted cover so they stay well vented and there is a drain pipe inside to remove any seawater that might make its way through the slots.
For this first load of diesel, we only took on enough fuel to do all the commissioning of diesel based equipment such as the Kabola KB45 boiler, all the fuel transfer pumps, Alfa Laval fuel centrifuge, fuel polishing system and Mr. Gee of course and then enough for the first set of sea trials.
Hence, we only took on a “measly” 2150 Liters / 567 USG out of the 14,600 Liters / 3860 USG that we will take on prior to our first passage. However, as per the intro, all donations are still very much welcomed!
X marks the Spot!
OK, are you ready for the final milestone that Christine and I just completed yesterday?
Does this help you guess what we are up to?
Helpful hint: It took place UP here.
That’s right! Time to apply these CNC cut vinyl letters and numbers to put the XPM78-01 markings big and bold on Möbius’ Bow.
All pretty simple to do. First mark off the top edge of the lettering with a straight edge and pencil.
Give the area a good cleaning with 3M Scotch Brite pads and water, rinse well and then sponge on a coat of clean water with lots of liquid dish soap in it so you can slide the lettering as needed to get it perfectly aligned.
Peel off the inside layer of the peel & stick lettering and press it onto the soapy wet hull and use your fingers and a plastic spreader to squeeze out all the water and get all the letters and numbers perfectly aligned and adhered to the hull.
Then carefully peel off the outer layer and go over each letter with lots of pressure on soapy fingers and plastic scrapers taking special care to ensure that all edges are tightly bonded to the hull and there are no bubbles or wrinkles.
Bring in some cheap labour if you must.
Take your time to go over each letter and number several times.
Then stand back to check out the proportions and placement.
And yes, we would be delighted to be mistaken for a military/coastguard ship in the unlikely event that anyone is considering approaching us with mal intent!
Now THAT is a Bow to be proud of!
And that’s a wrap for the week that was February 01-06, 2021.
Thank you all SO much for taking the time to join us here and we hope you will be back again next week. In the interim please be sure to put your questions and comments in the “Join the Discussion” box below.
As Launch Date looms larger and sooner the theme of checking off all the “little Big” jobs on the punch list continues although we still have a few “Big” jobs such as painting the bottom with foul release paint which continued as well this past week so without any further ado let’s jump right in to see all those jobs both little and BIG that Team Möbius looked after this week of January 25-30, 2021.
One of the “little Big” jobs that we completed this past week is getting the propeller shaft fully aligned with the output flange on the Nogva Gearbox and hence this week’s title.
In this photo the dark Burgundy is the Aft Output end of the Nogva Gearbox and the bright Red is the flange on the propeller shaft which continues through the Tides Marine shaft seal system and out of the boat through the large AL prop shaft tube which is hidden here by the Blue Tides Marine silicone bellows hose.
This dimensioned drawing of the complete Nogva CPP or controlled Pitch Propeller, shaft, seal and flange will help orient things a bit.
Here I have gone below the boat rotate the CPP prop back and forth while pushing it hard forward so that the two flanges meet. A few months back we had spent quite a bit of time getting this alignment close as we installed the anti-vibration mounts on the Gardner and the Nogva and you read about that HERE, so now it was time for the fine and final adjustment to get these two flanges perfectly aligned.
As you may recall from previous posts the two flanges need to be eXtremely closely aligned both concentrically as per the illustration on the Left and also laterally as shown on the Right. Maximum deviation we are allowed is up to 0.005mm / 0.002in (human hair is about 0.05mm diameter) and ideally we are going for zero.
Needing such perfection I called on my Perfect Partner, aka Captain Christine to assist and although she is prone to laying down on the job (sorry, couldn’t resist) she was a huge help and made this task go much faster.
We check the alignment by inserting a thin feeler gauge, which is the silver strip you see here, that is a tight sliding fit into the space between the faces of these two flanges and see what the gap is at 12, 3, 6 and 9 o’clock. Any difference in size of the gap at these locations tells us how far it is out either horizontally at 3 & 6 o’clock or vertically at 12 and 6.
Adding to the challenge the prop shaft needs to be supported in its perfectly centered position which my red hydraulic bottle jack is looking after.
Mr. Gee, our Gardner 6LXB is solidly bolted up to the Nogva Gearbox so they are essentially an eXtremely solid single unit that is supported by six anti-vibration mounts such as the Silver one you can see on the Stbd. side of the Nogva Gearbox on the far Right in this photo. You can see the large vertical threaded part of these mounts with the large supporting hex nut on the bottom and smaller locking nut on the top.
To align the flanges vertically I need to turn the large nuts at the very front of Mr. Gee or these back two on the Nogva, Up/Down to move the Nogva flange until the gap is zero all the way around.
The process then is for me to go around the four Front/Rear mounts and turn those big nuts Up/Down while Christine moved the feeler gauges around the circumference of the flanges and called out the differences in the gap to me.
With Christine laying down in the space behind the Aft end of the ER Enclosure overtop of the Tides Marine seal at the bottom, there wasn’t enough room to take a photo but this previous shot shows what she was doing as she reached in with the feeler gauges to check the gap and call out the differences to me. Doing this all by myself was very time consuming so now you see what I called in the Big Boss to help out!
It still took us almost 2 hours but in the end we got the gap down to zero such that both flanges were touching all the way around.
With these two flanges now fully aligned we could insert the 8 hardened Grade 8 bolts through both flanges and torque them down to 120NM and the alignment was done!
White grease is TefGel 45 to prevent any corrosion and ensure that these nuts are just as easy to undo after many years on the job when we need to remove the prop shaft or the Nogva/Gardner for some reason in the distant future.
Many of these “little Big” jobs are like dominos in that as getting one done lets you do the next. So with the flanges aligned and mounts all torqued down I could now finish installing the Tides Marine SureSeal system. This is an eXtremely critical bit of kit as this is responsible for keeping the prop shaft cutlass bearing lubricated with a flow of fresh sea water AND keeping that sea water OUT of the boat!
Here is what the real deal looks like now fully installed. The Blue silicone “Articulating hose” in the illustration above, is double clamped onto the Stern or Prop Shaft Tube at the bottom and onto the Black SureSeal housing at the top.
The way this works is that inside the SureSeal are two stationary rubber lip seals with the 65mm OD Prop Shaft rotating inside them that keeps the water sea water inside the Prop Shaft Tube from being able to get past and into the boat.
We keep a VERY close eye on that Blue silicone hose over the years as if it were to ever rupture we would have an eXtremely large volume of water flooding into the boat!
The Black ring at the top is the very handy holder for a second set of replacement lip seals which you can change out with the boat still in the water as you don’t have to remove the Prop Shaft to replace them; just pry the old ones forward, cut them off and slide the new ones into place.
Last part of installing the SureSeal system is to provide a pressurized flow of fresh sea water into the Prop Shaft Tube which travels down the tube and lubricates the Cutlass bearing which supports the Prop Shaft as it exits the boat.
One of the reasons I chose to locate the Silver Heat Exchanger you see in the Upper Right was to be able to tap into its drain plug on the salt water side and use this as the source of pressurized salt water for the SureSeal. Nice short hose run and Cihan had that all hooked up in no time. The second Red hose on the Left goes up along the Aft wall of the ER with a ball valve on the end of it so that I can check the salt water flow rate when we first start up and from time to time afterwards and ensure that there is at least 4L/min / 1USG/min when the engine is idling.
Both those little Big jobs checked off the list and this is what the finished result looks like when peering down into the space Christine has now vacated on the outside of the Aft wall of the ER. Silver Gardner Coolant Heat Exchanger bottom right, Tides Marine SureSeal middle Left and Red Prop Flange middle Right and the Red Nogva Gearbox Oil Heat Exchanger at the top.
To keep the ER air tight a 6mm AL plate is bolted with a gasket over top and covered wtih the same composite grid floor plates as the rest of the Workshop and ER.
Cihan checked off another Big little job by plumbing the Sea Water and Engine Coolant water lines up at the forward Starboard/Right corner of Mr. Gee and the ER. It is pretty busy up there so I’ve labelled some of this plumbing to help you make sense of it. Can be a bit confusing as there are three fluids running around here; Sea Water that comes in via the Sea Chest just visible on the far middle Right here and through the Strainer and Manifold on its way to the Jabsco Impeller Pump and then out of that Pump and into the Engine Oil Heat Exchanger where it runs Aft exiting out and into that Silver Sea Water Heat Exchanger you saw up above in the SureSeal installation sequence.
Hope you got all that because YES children that WILL be on the Test on Friday!
Driving Big Red #2
Over on the opposite Port/Left side of Mr. Gee I finally have the drive system for our second Electrodyne 250Ah @ 24V alternator all designed and the adapters all machined so time to get them all installed. You may recall this photo from THIS previous blog post about installing what I call Big Red #2 and how I intended to drive it from the PTO or Power Take Off on the Gardner using a Jack Shaft I had from a previous job.
This is a quick screen shot from my Fusion 360 design for the adapters at either end of the Red JackShaft. Green cylinder on the far Left is the Output shaft from the Gardner PTO, Purple is the AL adaptor to couple the Jackshaft to the PTO and at the far Right in Gold is the steel multi V-belt drive pulley that came with the Electrodyne which I will machine with four threaded holes to bolt the other end of the Red Jackshaft to.
Note: Jackshaft simplified here to just a rod with flanges at either end.
This is the PTO from the Gardner with that Purple aluminium adaptor in the rendering above now pushed onto the Green PTO Output shaft and secured with four round hex head through bolts.
The Red Flange on the front U-joint end of the JackShaft barely visible on the Right will bolt to that AL adaptor with four more M6 SS bolts.
This is the Aft end of the JackShaft where this U-joint will be similarly bolted to that steel 8V pulley on Big Red #2.
The day came to an end at this point yesterday so not quite finished but this shot will show you how the whole JackShaft will connect the power from the PTO back to Big Red #2. This monster Electrodyne alternator could absorb as much as 10HP at full 250 amps of output which the gear driven PTO can put out easily and this Cardan or Jack Shaft should be more than up to the task.
Stay tuned for more though folks on the final installation of Big Red #2 next week AND just wait till you see the sweet setup I’ve come up with to drive Big Red #1 using a cogged timing belt setup that is now almost done.
Well Sand My Bottom!
Also not quite done but work continued this past week on getting the bottom underwater portion of the hull all primed and filled in preparation for applying the silicone based Foul Release paint, International InterSleek 1100SR.
The Paint Crew finished applying all the epoxy filler to smooth out all the welds and create a sleek smooth surface for the InterSleek 1000SR Foul Release top coat to come.
You can see some of the filled welds around the Prop Tunnel above and
….. the filleted edges around the AL threaded mounting disk for the Zinc on the Rudder. The circle on the Right is the filled in through hole we put in the Rudder to make it possible to remove the Prop Shaft without having to drop the Rudder. Because we hope to not need to remove the Prop Shaft for many years this hole is filled in to provide a fully flush curved surface on the Rudder sides to maximize a smooth laminar flow of water over the Rudder.
Sanding the first coat of epoxy filler on the Keel and Prop Tunnel into smooth large radius coves.
….. and the Aft Depth Sounder transducer.
…. and one of the 5 Sea Chests.
By end of the week they had the last of the 5 coats of International epoxy primer rolled as you can see around the Bow Thruster Tunnel, another smaller Sea Chest intake and Zinc mounting disk up near the bow.
Final coat of epoxy primer being rolled on Aft and we’ll see the application of the InterSleek 1100SR next week.
Grand Dame of Dyneema!
Lest you should think that The Captain only lays down on the job, this will prove that she sometimes sits!
But Christine has become and expert Dyneema splicer after doing so many as she installs all the Lifelines around the Main Deck. This are the AL Stanchions with their Lifelines now in place on the Aft end of the Port/Left side. The Tender will come On/Off this side so these 3 LifeLines have Pelican Hooks that are easy to release so we can then pull up the Stanchions and roll up the whole setup and stow when the Tender is aboard.
Closer view of how these Pelican Hooks and Thimbles work.
You start to appreciate how Christine’s Dyneema splicing expertise has developed so quickly when you start to count up all the splices required for each LifeLine in the system we’ve come up with. On the far Right is an endless loop that wraps around the AL Stanchion through a small AL D-ring to keep it in place and a SS Thimble captured on the end. Last step of this will be to lash the loop around the SS Thimble closed so that when it is undone the Thimble can’t come out.
Looking down the LifeLines to the Left you can see another splice at the Left end of the Pelican Hook and then further Aft/Left two more around these Black anodized Donuts or Rings you can see further to the Left. Christine leaves a gap of about 80-100mm / 3-4” between these two rings and then wraps multiple lashings between them to tension the life lines. And of course each of these Rings require yet another splice!
Hilmi and Ramazan continued their work inside Möbius this past week and we also find more of Captain Christine’s fingerprints up here at the Main Helm where she and Hilmi have been working to install and connect Boat Computer #1 you see here on the Port/Left side of the Main Helm Chair.
Its ultimate home will be inside this space behind the 50” Monitor on the outside and this AC/Heating Air Handler inside.
This space is normally covered by this hinged Rosewood back with a recess for the adjustable mounting system for the 50” monitor that doubles as both our movie watching entertainment screen when on anchor and then one of 4 screens for boat data and navigation when underway.
Down in the Guest Cabin Ramazan is completing the last of the Ado LVT vinyl plank flooring.
While the smallest by surface area it has ELEVEN removeable sections above the bolt on tank access hatches below so this area is taking the most time.
Pull out Bed in the Upper Left and Christine’s Office desk on the Right.
Six of those removable floor sections all weighted down while the adhesive dries.
Removable floor sections?
What removable floor sections?
Ramzan then stepped up his game (sorry) by moving up to install the vinyl flooring on the steps leading up from the SuperSalon to the Aft Deck.
Another tricky and time consuming bit of detail as each step has one of these handrail posts he needs to go around.
Which, as you can see, he had no trouble doing eXtremely well!
And that’s a wrap for the week that was January 25-30, 2021. Yikes! The first month of 2021 gone already???
Well at least it puts us another week closer to LAUNCH so as with “being shafted” that is all a very good thing.
Thanks for joining us for yet another episode here at Möbius.World. REALLY appreciate and value you doing so and please feel encouraged to add your comments and questions in the “Join the Discussion” box below.
Hope to see you here again next week.
Most of Team Möbius was MIA again this past week but once again the combination of those who were working along with the outside contractors working this week, a LOT of very eXciting progress was made this past week of Dec. 21-25, 2020.
And somehow or another Christine and I also managed to include a wonderful Christmas celebration to end our week and carry on through to tonight, Sunday, when as soon as I finish writing up this blog post we will sit down to enjoy Christine’s turkey soup which is one of the many great outcomes of all the work she put in to create a fantastic gourmet Xmas turkey dinner with all the fixin’s’, dressing and gravy! Guess what? Turns out that I’m not the only turkey in Turkey! Who knew??
As in some previous weeks, there were a lot of “small jobs” that we were able to check off the punch list this week and taken together they add up to a very big deal. That saying “Don’t sweat the small stuff; and it’s ALL small stuff” could not be truer than in a big boat building project like this. So I may jump around a bit but there is one eXtremely BIG job that got done this week and is an equally big part of the title of this week’s Progress Update.
But this blog post is between me and dinner so let me jump right in with what will likely be a very rapid fire Show & Tell which I hope you will still enjoy.
EXTERIOR PREP WORK:
We only had Uğur on the job for Monday and Tuesday this week but he still managed to be his usual productive self and looked after several important jobs such as this one.
The shot is taken from down in the Engine Room looking up through the big open hatch overhead to catch Uğur finishing up the AlucoBond paneling that surrounds this hatch.
Up on the Aft Deck now, you can see how he had attached the AlucoBond outer liner to the Hatch itself last week, and also installed those beautiful Bofor dogs and latches that keep this hatch solidly in place and fully watertight.
This week he is finishing up the work on the AlucoBond walls and ceilings in the ER by using Sikaflex to adhere and seal the AlucoBond paneling that is bent up around the inside circumference of the opening such that the whole ER is fully sealed now.
Uğur was in an “AlucoBond state of mind” this week I guess so he also finished off the AlucoBond panels that form the ceiling above the Outdoor Galley on the Aft deck.
Hilmi has the LED lights all wired and snapped in place so Uğur was able to put in a small bead of Sikaflex around all the outside edges and around the support poles to seal the whole ceiling.
eXciting for us to see as well was when this was the first area to have all that protective film with the Red & Black AlucoBond printing on it and reveal these very reflective satin White plated aluminium surfaces.
Another one of those “small things” but what a difference to see these finished surfaces at last!
More small but important jobs done this week was when Ali finished covering all the newly applied TreadMaster non skid surfaces with some protective cardboard. This is the Port/Left side of the Swim Platform and the stairs leading up to the Aft Deck.
There is still a LOT of work to do to finish Möbius so these areas will be seeing a lot of foot traffic, tools and materials so the cardboard will help keep them clean and new till Launch Date.
The dogged door on the Right is the HazMat locker for any flammable or odiferous items we want to store onboard and keep completely isolated from the interior of the boat. Winch handle is how you open the Bofor dog latches.
Opposite side of the Swim Platform with the WT door, currently removed, into the Workshop and Engine Room.
Ali also has all the Aft Deck all covered with cardboard sheets and fully taped down.
Same story up on the Front Deck and Anchor Deck TreadMaster.
All the solar panels are also covered with protective cardboard sheets. In the case of the solar panels this is both to keep the glass surfaces clean as well as the safety aspect of keeping all sunlight off of these panels so that they are not generating any power that could cause problems to equipment and workers.
FINISHING UP the HOTWORKS on the TENDER:
Down on the shop floor off to the front right of Möbius, Nihat was also with us for Monday and Tuesday this past week and was able to finish off the last few small jobs to complete the “hotworks” or welding up of the Tender.
This is the Aft Port/Left corner of the Tender with the Engine Bay lid opened up. Nihat is grinding all the welds down flush and then doing the final sanding of all the AL surfaces with a random orbital sander with the same finish that he has perfected from all his work doing the same to the outer surfaces and hull of Möbius.
A sneak peak at the interior of the Engine Bay where you can see the Port side Engine Bed starting where Nihat’s foot is and the framed opening for the Castoldi 244DD jet drive behind with the “Mickey Mouse” cut-out in the thick transom plate.
This will likely end the work on the Tender until after we launch Möbius and I can spend the time to do all the outfitting installing the Yanmar 110HP 4cyl diesel inboard engine and the jet drive.
SNEAK PEAK at the FINISHED INTERIOR:
An American couple and their son, who are also faithful followers here on the blog and have become very interested in having an XPM of their own, came by on Tuesday for an extended tour on Möbius and visit with Naval Yachts and the Free Zone.
So on Monday we all pitched in to remove all the protective plastic and cardboard covering up all the interior surfaces so they could see what is underneath and the quality of work that Team Möbius is capable of producing. Möbius received a much needed and very thorough cleaning to look her best for these prospective new XPM owners.
Both their visit and seeing Möbius at her clean and shiny best were equally eXciting for Christine and I, so let me capitalize on this opportunity to give all of you a sneak peek of the interior. I will go through this in very rapid fire fashion, so hang on as we take you on a quick whirlwind tour of the freshly cleaned and exposed finished interior of mv Möbius
Staring up at the very front of the interior in the Master Cabin, this is the Vanity Sink which sits front and center up against the WT bulkhead with the Forepeak on the other (very well insulated )side.
Flanked by the Washer & Dryer behind the Blue/Green leather doors on the Right and the Shower on the Left.
Almost complete and just waiting for the 2 thin strips of mirrors on either side of the soon to be mirrored door above the sink.
Sorry, I can never resist the glowing beauty of this unique hand painted all glass sink.
Note the combo 120V + 240V plug behind the sink and spread throughout this “world wired” boat.
Stepping back a bit will help orient you to the Master Cabin and you can now see the whole Starboard/Right side bank of cupboards and wardrobes with the Washer & Dryer at the front.
On the Left side is the door into the Head/Bathroom as well as the adjoining Shower hiding behind that etched glass corner wall.
Before I continue walking back, a quick peek through the door into the Head to show the matching rectangular Blue glass sink inside. The vertical doors above are anxiously awaiting their mirrors.
Bidet VacuFlush toilet is just visible on the bottom Right and the adjoining Shower is on the far Left.
Continuing aft one step at a time reveals the full etched corner walls of the Shower.
One more step back and the Master Bed comes into view with its overhead boxed ceiling and the Bureau of Drawers on the far Right side which is also waiting for the big mirror that will soon be mounted inside the Rosewood framed side wall.
Just wait till you see this space filled with a hanging 3D textile sculpture of our Möbius strip which our artist / niece Lindsey created for us!
Baking up ALL the way Aft in the Master Cabin and starting up the stairs to get this shot looking down into the entrance to the Master Cabin.
The door which goes here is one of our Swiss Doors that I’ve shown in previous months which do double duty by being a door in two positions. Here it is the door in the large full height Wardrobe on the Right as you walk in here, and then this same door closes this entry into the Master Cabin itself. Brilliant! if I do say so myself and eliminates one complete door here and two more back in the Guest Cabin.
Going back up to the front of the Master Cabin and looking Aft now, you can see how that door on the Left of the stairs is now closing off the Wardrobe behind it and can then be swung “open” to close off the Entryway into the Master Cabin.
One last shot in the Master Cabin before we head upstairs to check out the SuperSalon. This is the two stairs that wind their way up to the platform on the Port/Left side of the bed. This platform serves multiple purposes;
* the HVAC Air Handler is housed below inside this platform
* provides easy access for Christine getting In/Out of her side of the bed
* easy access when making the bed
* when on long passages and covered with a custom fit memory foam mattress, this platform transforms into a very safe and comfortable bed for whichever one of us in Off Watch in really rough weather where the high sides keep you safely snuggled into bed no matter what Mother Nature is doing to Möbius on the outside.
SuperSalon, GALLEY, MAIN HELM & LOUNGE areas:
Continuing with this “one step back” tour of the interior, let me head up the stairs out of the Master Cabin which you can see at the bottom Right here and take you on a quick tour of the whole SuperSalon.
Main Helm on the Left here and the forward end of the L-shaped Dinette seat on the bottom Right.
One more step back into the space where the Dinette Table will soon be mounted on that aluminium XY Slider peeking out of the bottom Left corner. Dinette Settee on the bottom Right, Main Helm Chair middle Left with the forward electrical control panel partially open on the Right side of the Main Helm.
Two 19” touchscreen daylight readable monitors will soon be mounted into those two rectangular openings on the Black leather covered panel front and center of the Main Helm dashboard.
Sliding over to Port/Left for a better view of the Main Helm and where those two monitors will be mounted. Stairs down to the Master Cabin through the space on the bottom Right.
Look closely and you will be reminded that all the 26mm triple laminated safety glass windows are now fully installed around all 360 degrees of this truly SUPER Salon.
Stepping back on the Port side the Dinette Settee comes into better view now and you can now see how that gorgeous Zwaardvis AL pedestal works. Up/Down Z axis adjusts with an pneumatic lift cylinder inside the 2 stage pedestal and then the table top can be moved 200mm/8” in the XY axis to adjust the table to Goldilocks position Left/Right and Fore/Aft.
Pivoting to Stbd/Right side for a better view of the Settee, pedestal and a sneak peek into the Galley.
Stepping back yet another step or two to go up the stairs leading out of the SuperSalon to the Aft Deck, reveals the twin 130 liter side by side Vitrifrigo refrigerators nestled inside their Ro$ewood cabinets on the Left and some of the countertop Galley Garages on the Right.
Two more steps up those stairs to give you this shot looking forward and down into the Galley on the Right, dual door fridges on the Left and if you turn Left at the bottom of these stairs you will continue down a matching staircase to the Corridor leading to the Guest Cabin and Workshop.
Staying on that same top step at about Aft Deck height and pivoting towards the Stbd/Right side of the hull to give you this overhead view of the Galley and its surrounding Galley Garages.
Stepping into the Galley itself briefly to see the four burner Bosch induction cooktop with built in central exhaust fan and the matching Bosch Smart Oven that automagically combines convection, microwave and broiler elements to cook each dish to Goldilocks perfection.
Double SS sink inset into the Turkish Turquoise marble countertops. Smaller faucet on the Right is plumbed direct to the 150L fresh water “Emergency Tank” that is independent of the rest of the fresh water system for some “just in case” backup of always ready very fresh water.
Moving forward for a change provides this perspective of the full Galley looking Aft towards the Rear Stbd/Right side.
Stairs up to the Aft Deck and the Outdoor Galley on the far Right here surrounded by windows, windows, windows with views, views, views everywhere you look.
Just before we leave the SuperSalon, a rightfully proud Sinan posing with his masterful upholstery work on the these Sky Blue Ultra Leather covered Settee cushions. Just imagine what they will look like when we finally get to remove al their plastic covers!
Table is down close to its “bed” position here and the Black release handle for the XY slider is hanging down below waiting to be mounted to the underside of the table next week.
Trying not so successfully at being incognito, Captain Christine aka my Beautiful Bride, couldn’t resist the chance to try out her first sitting at the Dinette table with it now at full eating/working height.
Looking straight Aft at the stairs and out the door onto the Outdoor Galley on the Aft Deck here. Dinette table back down into Bed mode with Coffee Table mode in between and the stairs leading down to the Corridor and Guest Cabin on the far Right.
Apologies for not getting better shots of it but over on the very Aft Left corner of the SuperSalon the stairs just out of sight below here lead down to the Corridor that takes you Aft through a WT Bofor door if you keep walking straight and if you turn Left you have the Guest Bathroom/Head on your Left, Shower on your Right.
If you walk straight ahead now, you enter Guest Cabin/Office and can see the fold down Latte coloured Ultra Leather Couch/Bed in the bottom Left with the Pullman Berth that Sinan is about to pull down above.
This Couch has been custom designed for Christine to be her Goldilocks “pondering pad” when she is cooking up the next plot twist in her next sure to be a best seller thriller novel with its super wide base to give her plenty of room to relax and curl up.
Then the bottom portion pulls all the way out towards you and turns this into a full Queen size bed.
Christine’s Office desk just visible on the far Right here with printer bay on the left side of the desk and plenty of bookshelves above and on the opposite side of the Couch
Need more bed space in the Guest Cabin you say? No problem, flip up two latches ……………………..
…………….. and the Pullman Berth folds down to provide yet another single bed as Sinan demonstrates here.
Before you know it was Thursday and time to cover everything back up again for the next few weeks of finishing off the interior.
So here’s the deal folks. It is now past 21:00 for me here in Antalya at the end of a wonderful Christmas weekend and the Chef has been eXtremely patient with me, yet again, and keeping her Turkey Soup on the boil. I still have not gotten to that BIG exciting job that happened this week and is the key to the “Much Clearer” part of this post’s title BUT, I’m going to have to disappoint you or at least keep you waiting until next week to cover all that.
For now, let me just end by wishing ALL of you a VERY Merry Christmas and that you all find ways to make this last week of 2020 as good as it can possibly be. I’ll be back to you next weekend with the latest Weekly Progress Update and really hope you will join me again then.
A bit of a slow week progress wise on XPM78-01 Möbius this past week as our work week was unexpectedly reduced to four days due to a complete power outage at the Antalya Free Zone where Naval Yachts and about 30 other shipyards are located. We are now entering the wet winter season here in Antalya and while we have been having some spectacularly beautiful blue skies and sunny days, the rain has also been arriving along with LOTS of thunder and lightning last weekend. I assume this is what took out the power in the Free Zone and gave us all an unexpected “snow day” off as we used to call it when I was a kid growing up in various parts of Canada where we would often get so much snow overnight that the roads were all impassable and so all the schools would close. Oh drat said all the parents, Oh Yayyyyyyy, said all us kids! While I’m still very young at ❤ I was now saying “Oh Drat!” at not being able to work on Möbius at Naval but I just turned my bike around and pedalled back home to work from there so it wasn’t a totally lost day.
Several members of Team Möbius were not working on Möbius this past week but for those of us who were we did get lots done so I have plenty for this week’s Show & Tell for you and I also have some photos to share that I didn’t have time to include in the past few blog updates. So grab a comfy chair and tasty beverage and let’s go see what happened onboard the Good Ship Möbius for the four days of December 15-18, 2020.
You will figure out this week’s Update title as you go through this posting where many of the jobs being worked on started wtih the letter “T” such as the dinette Table, the Tender, Teak shower floors and TreadMaster. A bit like when Sesame Street would be “Brought to you by the letter T” perhaps? and you will soon see what the “Ado” is all about so let’s get going ……………………….
First though, we interrupt our regular programming for a word from our sponsor, well MY “sponsor” so to speak.
** Wayne’s “mushiness” Warning!!! This next bit is NOT technical boatbuilding stuff so if that’s what you are anxious to get to, scroll down to the next section please.
For the braver souls and fellow romantics, read on……………
Happy 7th Anniversary of our First Kiss Captain Christine!
* If you have not already done so you may want to read my previous post here on 22 November for some context. It was titled “The simple comment that Changed My Life Forever Better” which it tells the story about how Christine and I first connected thanks to this little character; “Barney the Yorkshire Terror” .
If you read that story you will already know that I’m a hopeful romantic. (who would call romance helpless?!?!?!!?!?)
Given our rather unconventional first connection and all the equally unique adventures that followed, we have a LOT of different “anniversaries” and we LOVE celebrating every one of them, every year.
My favorite anniversary though is the one we celebrate today, December 19th of our very fist kiss on the very first day we met in person when Christine flew all the way from her sailboat in Florida to where I was on my sailboat in Fiji and I snapped this very fist photo of her as she walked into the Arrival gate at Nadi International Airport on 19th December, 2013.
Christine says that for her it was “Love at first Skype”, which happened about a month earlier and I won’t refute. However for me it was THAT FIRST KISS when we finally first met in person on 19 December, 2013 and I knew for sure that I had just kissed (and been kissed back I might add!!!) by the woman who would become my best friend, my lover, my wife, my Captain and my partner in life, for life.
Happy 7th First Kiss Anniversary my Love! Can’t wait to get started on our next set of adventures for the next 7 years together! First though, lets start by enjoying this First Kiss anniversary day with these flowers in our cozy little apartment in Antalya.
OK, OK! Now back to our regular programming ………………..
“T” is for Table
For those who were not with us last week, we saw Ramazan get started building this ro$ewood Table.
Which, when finished, will be mounted atop this very cool air assist height adjustable pedestal with that X-Y slider you can see in the background.
All this aluminium beauty comes from the Zwaardvis Pedestals company in the Netherlands and it is all “boat jewelry” in my eyes.
This Z-axis or vertical height adjustable pedestal has 2 stages for maximum height adjustment which is assisted by an internal gas lift cylinder similar to what you might have on the rear hatch of a SUV. You order these by the weight of your table top so the assist is just right and changing the height an easy single handed operation by simply releasing one or both locking handles, moving the table up/down to the height you want and closing the levers.
The XY slider, allows us to move the table 200mm / 8” fore/aft and side to side to also get the XY position of the table just right.
Up high and close in for eating or working and then down and out for more of a coffee table setup and then all the way down to put the table top and surrounding seats all the same height to create a very large bed for those rare occasions we have more overnight guests than our lovely Guest cabin with a Queen + Pullman bed can accommodate.
This is where Ramazan started on Tuesday with the solid 50mm / 2” solid Rosewood edging all glued with biscuit joints around the circumference. Then he has put a large 40mm / 1.6” radius around all the edges and given it a good sanding.
Now the table moves up to the 2nd floor Finishing Room where Neşet here is inspecting all the surfaces with a very fine eye in order to ……
……. find any remaining small spots that need filing in order to make them glass smooth after this first coat of clear Polyurethane “varnish”.
Then it is “rinse & repeat” four more times to build up the five coats of PU that goes onto each piece of Rosewood cabinetry.
This is how it looks after the 2nd coat has been applied and is ready for wet sanding before the 3rd coat is sprayed on.
“T” is also for Teak Shower Floors
We didn’t want any Teak on the exterior of Möbius, nor any SS, paint, etc. but we welcomed the use of Teak to make the removable floor inserts in both Showers.
Orkan is the Teak Decking specialist and Naval so he was the perfect guy to apply those deck making skills to these interior floors as you can see he has done masterfully here.
In keeping Low Maintenance as a top priority, we didn’t want to have a Teak grate style flooring so we came up with this self draining system where all the water simply runs off the four sides through these recesses and then runs over to the drain in the center of the fiberglass shower floor below.
These floor plates have a series of fiberglass “feet” on the bottom to keep the air/water space between the teak and the fiberglass and they can be easily lifted out to clean underneath from time to time.
The shower drains use the relatively new Whale Gulper IC Intelligent Control automatic Gray water pumping system. (click for full resolution of this or any photo)
We use diaphragm pumps almost exclusively for all our water, bilge, crash pumps on Möbius as our experience has taught us that these are FAR superior to centrifugal style pumps in that they have that proverbial “suck a golf ball through a garden hose” type of suction power and require NO filters or screens so they almost never clog.
The IC or Intelligent Control that Whale has added to these pumps makes them work all the better by having a simple solid state water sensing probe embedded in the Yellow manifold you see here which automatically turns the pump On/Off as needed and allows you to connect 2 different sources of Grey Water which we use to drain both the Master Bathroom/Head and Shower floors.
Simple and efficient, what’s not to like?!!
At the other end of the size scale of our diaphragm pumps is this brute underneath the Stbd/Right workbench in the Workshop.
It does double duty being both our high volume/high water bilge pump and our Fire “hydrant” system that pumps sea water from the Sea Chest to a fire hose and nozzle stored in he Aft Hazmat locker.
Several of you were curious about this pump so HERE is a link to the basic specs on our Feit PVM 1R diaphragm Pump.
* 24V 0.75 HP motor
* 120 Litres/min / 32 USG/min
@ 7 meters / 23 ft Delivery and 4m / 13 ft Suction
“T” is also for TreadMaster:
Another job continuing on from last week’s Progress Update is the laying of the last of the TreadMaster on all the aluminium decks and stairs. You can read all the details of the method in the previous posts and here is the TreadMaster Team; Faruk (Left) spreading the epoxy adhesive, Ali bringing the cut-to-size piece of TreadMaster to lay down on this epoxy, and Orhan following behind getting ready to cut the next piece.
Ali in position with the piece of TreadMaster that Orhan has pre-cut as Faruk evens out the peanut butter consistency West Systems epoxy with his V-notched spreader.
More “Rinse & Repeat” and they soon have the Aft Deck fully covered with TreadMaster. After drying overnight Ali covers all the fresh new Treadmaster wtih protective cardboard as these will continue to be high traffic areas during the rest of the build.
Taking a quick tour around the boat to show some of the other areas getting the full TreadMaster treatment.
Treads on each of the Spiral stairs up from the Aft Deck to the SkyBridge ready for their TM.
et Voila! Super safe, easy on the feet stairs up to the SkyBridge.
And same going back down.
Rough cut TM set in place down the Starboard/Right side of the SkyBridge with the 20mm / 3/4” spacers fast glued in place to keep the spacing just right while they are being epoxied down.
With all the SkyBridge deck sheets of TM cut to finished size with their radiused corners, Faruk and Ali get busy gluing them all down.
SkyBridge Helm Chair just set here for now. Once the TM all dries it will be moved aft to the Helm Station and through bolted in place there.
Hmmmm, with a view like this maybe a good spot for a 3rd or 4th Llebroc chair??
Swim Platform done.
Stairs on both sides going up from the Swim Platform to the Aft Deck all TM’d now.
Side Decks ready to have their TM glued down.
Front Deck all done and dusted!
Protective cardboard all taped down.
Anchor Chain Stopper all mounted so this Anchor Deck can now have all its TM glued down.
And the Forepeak Hatch has its Bofor Dog Latches all mounted and has received its full TreadMaster treatment.
Much “Ado” about Flooring!
This will just be a preview to wet our appetite for next week’s Möbius Progress Update and will complete the rest of this week’s title riddle for you.
This is a stack of the Ado LVT or Luxury Vinyl Tile “click-in-place” floor planks that we are using in all the interior floors on Möbius.
Ado is a HUGE Turkish building materials company and one of their specialties is Luxury Vinyl Tile or LVT flooring systems typically used in very high traffic situations such as airport terminals, commercial buildings and residential homes.
LVT is completely waterproof, Fireproof, made for use overtop of in-floor heated floors, quiet and eXtremely tough with life spans over 20 years even in very high traffic applications such as airport terminals so it seemed like the Goldilocks Just Right choice for Möbius.
This link will show you the white highly textured “Aperta 2010” we have chosen to use from their “Viva Series”. As per this label on the boxes, this is the “Click” type with a 0.7mm thick “wear Layer” as per the Tech Spec illustration above.
Tough to focus on but this is my attempt to show you how the interlocking “Click” system works. I suspect many of you will have installed flooring with a similar system in your homes and boats as this has been popular for over 20 years in the building trades and is a very DIY system.
Difficult to show how well textured this flooring is, but think well seasoned and aged wood decks on boats and homes and you’ll have it just right. We have tested samples with bare wet feet and it has proven it will be eXtremely non-slip throughout the boat.
Stay tuned for more as the Ado flooring installation begins next week.
”T” is also for Tender:
Nihat (seen here) and Uğur only worked on Möbius two days this week but I have all of their work from last week to catch up with you on so still plenty to show you as they finished off their “hot works” stage of welding up the aluminium jet drive tender hull.
Nihat has now had an eXtreme amount of practice at grinding down the welds on all the hull plates on Möbius herself so he was VERY fast at getting all the Tender’s welds flush and all the corners nicely radiused.
meanwhile, inside the Tender, Uğur was busy cutting in this access to the area underneath the bench seat in the Steering Console.
Like Nihat, Uğur is also very fast and he had this hinged seat lid all done in one afternoon from start to finish.
We will either just make up some rectangular seat cushions for the seat and back or perhaps buy some “bucket” style fish boat seats to go in here.
Uğur was even faster at welding in these two Lift Bridle attachment points up at the Bow.
And mere minutes later, these two matching ones at the Aft end corners down at floor level.
Next up was fabricating and attaching these two boarding safety handrails that go on either side of the flat Bow. Uğur is a master at these nicely radiused bends at any angle which work out better than using a hydraulic pipe bender for small numbers of bends.
A series of evenly spaced cuts with an angle grinder make it easy to form these different radius bends.
And then each cut is welded back solid.
All the welds are ground down and sanded and you’re done!
40mm / 1.6” OD thick walled AL pipe
These safety boarding hand rails needed to be removable so we played with a few positions and picked this one.
We used the very simple bolted flange system that we have used throughout the building of Möbius.
The thicker (10mmm / 3/8”) bottom flange is threaded and welded to the hull itself to create a base for the thinner top flange welded to the handrails to bolt to with NO penetration of the hull itself.
All four bases get tacked in place with the Handrails bolted to them so we can test for just right position before fully welding the threaded bottom flanges to the hull.
Super Polisher Nihat then comes in and cleans up the welds and the hull areas around them and it is all done!
I will probably pick up on the work to complete the Tender by installing the Castoldi 244 Jet Drive and the 4 cylinder Yanmar HTE 110HP engine, but that will all need to wait till after we launch Möbius so this may be the last you see of the Tender here for the next few months but do stay tuned for that and the test drive!
And that’s going to be a wrap folks for the 4 day week that was December 14-18, 2020 here at Naval Yachts and onboard the Good Ship Möbius.
Thank you SO much for taking time out of your busy day to join me here and hope you will do so again next week. Love to get your thoughts, questions and suggestions on any of the above so please type them into the “Join the Discussion” box right down below.
With Team Möbius back to work and augmented by additional sub-contractors the rate of progress was at an all time high this past week so there is a LOT to Show & Tell you about this week. I will apologise in advance that this week’s Progress Update may be a bit rushed both because I have so much to cover and it is now already mid afternoon on Sunday here. But before I jump right into all the progress updates, some other news from around the shipyard for you.
FINAL PLANS are SIGNED & SEALED!
The biggest news for Christine and I this week is that we finalized all the details for the final finishing of XPM78-01 Möbius with Naval Yachts and signed off on all the new addendum documents, which is what Baris (left) and Dincer, the founding brothers of Naval Yachts are smiling about here!
With projects of this size and complexity and especially for such a unique first XPM series build, there are a LOT of changes and adjustments along the way and a LOT of equipment, materials and sub-contractors that needed to be ordered and it has taken all of us more hours than we would like to know, to sort out all these details and get them all formally documented. So we were elated to have all four of us, Builders + Owners, sign off on this Friday afternoon.
Wayne Looses 1 old Titanium Screw and Gains 7 new ones!
Immediately after we all signed the new addendum on Friday, my elation transformed into something else when I spent several hours “under the knife” in the Dentist’s office! Another reason why this blog post will be a bit rushed as I’m not quite up to full speed again just yet.
For those curious to know, the scorecard from that surgery is that Wayne is now:
- one molar and
- one titanium screw (one of more than a hundred I have from a nasty motorcycle accident back in 1997) but now plus 6 titanium implant
- 7 titanium implant screws
- some extra jawbone (grafts)
- 29 stitches
I won’t bore you with any more details but given the somewhat technical nature of my posts and for those curious about dental implants, as I was, here is these 2 illustrations will give you the basic picture of what’s involved.
Now it is just a waiting game to get the stitches removed in 10 days and then let the jawbone and implants merge for two months or so before I go back to have the ceramic (Zirconia) crowns put in and I can chew again!
Möbius gets a New Neighbor
This actually happened two weeks ago so I’m a bit delinquent in posting this but we now have a new neighbor off of Möbius’ Stbd Aft corner.
She’s a Turkish flagged boat “Celeb” and is in the yard at Naval Yachts for some relatively minor work and some out-of-the-water winter storage.
Once again, our friendly neighborhood 72 wheel Yellow boat mover was called in for this move and it all came off without a hitch as usual.
There were more changes to the neighborhood a few blocks away from us over on the Free Zone side of the harbour where they are completely redoing the shoreside facilities to put in an all new humungous dry dock and other launching facilities.
This work has been going on for quite a few months already with the removal of the existing concrete walls, the whole rail launch and TraveLift launch facilities and a whole lot of dirt to enlarge the water area.
That leaves the Free Zone with no launching facilities but fortunately just on the other side of this harbor in the background here, is Setur Marina and so the authorities can open up the gates and let the boat movers bring boats in/out of the marina and into the Free Zone.
With Möbius’ launch date *hopefully* coming up early in the New Year it is likely that we may need to launch into Setur Marina rather than inside the Free Zone harbour. Either way works fine as the emphasis for us is LAUNCH ASAP!!
This pile driver has been running non-stop 24/7 for the past week putting in over 20 so far of these steel cylinders which I presume will be filled with concrete to form the underlying foundation for all the new concrete and dry-dock equipment to come.
OK, with this week’s episode of “What’s New in the Neighborhood”, let’s get back to the shipyard and get you caught up on this past week’s progress on finishing XPM78-01 Möbius.
LITTLE JOBS = BIG DEAL:
As I did in last week’s posting, let me quickly run you through a set of several “little jobs” which got looked after this past week. Some of you sent in comments noting that you liked the more rapid-fire sequences of work so I will repeat that here and please do let me know how well it is working or not by putting your comments in the “Join the Discussion” box at the bottom of every blog posting.
And as I noted last week these may be “little” in terms of amount of work, these jobs are all play very important roles themselves and perhaps most important of all are what define a FINISHED yacht!
First good example of how these little jobs can be so important was the finishing of the door into the Engine Room. Uğur and Nihat had fabricated and mounted this door many months ago but it needed to be fully insulated with fireproof EPDM insulation covered with the laminated aluminium/composite sandwich AlucoBond material you have seen being used to cover all the walls and ceilings of the Engine Room and Workshop.
They started by welding in these short lengths of aluminium L-bars for the AlucoBond to be fastened to.
Then Nihat cut the 50mm / 2” thick EPDM foam insulation and fitted each piece into their compartments.
AlucoBond is then cut to size and screwed in place.
Uğur than installs two of the same beautiful Bofor Dogs & Latches you saw him installing in the big AL hatches up on the main deck for the Forepeak and Engine Room.
Then the door can be remounted on its hinges while it awaits the 26mm thick tempered glass window to be installed to complete this door.
Next up for the same basic treatment was this hatch that goes into the floor in the SuperSalon to provide the only access to the cavernous Basement which sits under the entire SuperSalon floor.
Same 50mm EPDM foam is inserted into each of the little bays formed by the reinforcing AL stringers of this hatch, which is upside down here BTW.
Then Uğur spreads on a light coating of contact cement while ……….
……. Nihat cuts out the thick foil covered fireproof cloth that will cover and protect the EPDM insulation.
With the foil cloth all glued down, Nihat finished off the edges with some AL foil tape and this hatch was then mounted to the awaiting piano hinge in the Salon floor opening into the Basement.
The first of many “little” jobs in getting the below the waterline portion of the hull all prepped for the upcoming application of all the epoxy primer preceding spraying on the International InterSleek 1100SR Foul Release bottom paint we have decided to use.
Here Uğur has removed the propeller blades on the Vetus Bow Thruster and sanded all the internal AL surfaces.
I was able to pull my weight a little bit this week as well by finishing off some similarly small but important jobs, as well as one quite BIG BEAUTIFUL BEASTLY job on Mr. Gee, our Gardner 6LXB engine. More on that later.
The Black cone and disk up near the top Left here is the front end of the Chain based Hand Cranking system that I am now starting to mount. I have pulled it far forward here in order to mount the cast AL coolant tank.
Below this tank on the Right is the secondary fuel filter and return line and in the weeks ahead you will be seeing much more of that flat rectangular Pad in the bottom Left where I will soon be mounting one of the Big Red Electrodyne alternators.
A classic example of how Gardner leaves nothing to chance is this cast in place detail of how you need to use the correct type of anti-freeze and fill it to the correct level.
Big Red #2 near the bottom Left with blue taped box, as I’ve taken to calling the second 250A @ 28V Electrodyne alternators is the much bigger job I worked on this past week and I’ll cover that in more detail a bit later in this post. With this 2nd alternator now securely mounted to the side of Mr. Gee I was able to finish installing these beautiful copper oil lines that snake their way around Mr. Gee to carry his lifeblood engine oil to and from where it needs to go.
Large AL unit taking up the center of of the photo above and aft end here, is the complete fuel pump and mechanical injection system. The six vertical (5 Black 1 Red) levers you see in the photo above allow you to hand prime each of the 6 fuel injectors as well as shut off one injector at a time to check performance while running.
Burgundy cylinder in the top middle is the secondary oil filter housing with its copper oil lines bringing oil to/from this filter.
A few more finishing touches on Mr. Gee’s Stbd/Right side such as the exiting salt water hose now connected to the rear of this gorgeous cast bronze engine oil cooler, and the vertical braided SS mesh exhaust connector in the upper Left here is now bolted to the aft end of the cast iron exhaust manifold.
In the bottom middle of the photo above and up close here, the Black 24V Starter is now fully installed and connected. Two Red cables as one is from the twin FireFly G31 starter batteries and the other cable can connect the starter to the massive House Battery Bank in case the starter batteries should ever not be working.
Beauty & the Beast’s Love Child?
Take note in the 2 photos above of how Gardner attaches the starter to the massive cast aluminium crankcase with that silver strap and you can see in this illustration from the 6LXB Parts Manual how they attached the standard Gardner alternator in the same way over on the opposite side.
I wanted to mount Big Red #2, which is what I’ve come to call the second Electrodyne alternator, to the same place that Gardner used but would Big Red fit? Only one way to find out; try it! As did Gardner, I first made 2 shims from some AL 10mm plate to adjust the radius of the cast in place ribs to match Big Red’s 188mm / 7.4” outside diameter and bolted them in place as you can see here.
Here is an uncluttered straight on shot of the mounting base for Big Red #2. Fuel pump bowl in the upper Left corner, bottom of the cast AL injection pump running across the top and you can see the two “nubbins” where the hinge pin will slide through to hold the forked bolt that tightens the flat strap to cinch the alternator up tight.
That forked bolt is part # 11/19/20 in the illustration above but with Big Red being a bit on the Beastly side of the girth scale the original forked bolt was too short so I whipped up this new larger and longer version out of some SS plate and threaded rod.
I fashioned the fork out of a small block of SS and tapped it for a M10 threaded rod and threaded the two together. A SS nut to lock it in place and then for added safety and strength I thought it best to TIG weld the nut and threaded rod to the fork.
I will give you that I can be given to some hyperbole and eXaggeration from time to time but I think you need to give me that it is no eXaggeration to suggest that “shoehorn fit” describes this situation?!!
Each GE 250-24 Electrodyne alternator tips the scales at 40 kg/88 lbs and so again I will make my case that calling these Red Beauties Beasts is also no mere Hodgins Hyperbole!
As you might imagine, I had to take Big Red #2 in and out quite a few times as I adjusted its position and tested out the strap mounting setup to get that all to work out and still clear everything. Fortunately and as I’ll explain in a bit, took advantage of the fact that I had to take these alternators apart so I was able to cut their weight down quite a bit which made all my test mounting a bit less muscle building.
With the alternator temporarily held in place with some wood blocks I could test out the fit of this Black strap which is has a 10mm / 3/8” pin that slides through the bottom as you can see in the illustration above and the bottom of this photo.
Up at the top you can see the nut on the end of the upper forked bolt what cinches the alternator tight up against the radiused ribs you saw earlier.
I am close here BUT the large copper wires that carry the AC current out of the alternator need to come through that hole in the case across from my fingers, so I need to nudge it forward a wee bit more so the strap clears the hole.
Oh, and I also need to make sure that the length of this Jack Shaft with U-joints on each end that I am retrofitting to drive Big Red #2 from the Gardner PTO (Power Take Off) on the Left here.
(click to enlarge any photo)
I’m getting ahead of myself a bit so let me stop and provide a quick overview of these Electrodyne E 250-24 alternators that I’ve chosen to use and mount on Mr. Gee which I think will help you see how they truly are the Goldilocks combination or “Love Child” of Beauty and the Beast.
In addition to these basic specs my primary reasons for choosing these Electrodyne brutes include:
- truly rugged “beastly” construction and weighing in at 40kg / 88 lbs each
- Beautiful simplicity with only one moving part, the stator shaft and no moving electrical parts
- More simplicity being Brushless with no brushes and no brush springs
- One piece steel “double ended” housing with TWO alternators; one at each end.
- Remote Rectifier which moves most of the performance robbing heat outside the ER
- eXceptional life with 20,000 hours between recommended servicing
Here is what one looks like in real life. The box on top is simply a junction box where the 6 (3 from each alternator)AC current carrying wires emerge from inside the alternator body and connect to six large cables that go to the remote rectifiers outside the ER in the Workshop.
I ordered these alternators directly from Electrodyne in Oklahoma almost 2 years ago and spent a LOT of time with Dale Gould who is the Operations Manager at Electrodyne and he has been truly fabulous to work with on every level from getting these beasts built to the specs we decided upon, getting them shipped to me (not as easy as it sounds) and even creating little how to videos to show me how to do the alterations I needed on my end. Can’t thank Dale and his team enough nor recommend them more highly to you.
In the interim, I ended up changing how and where I was going to mount these two beastly beauties on Mr. Gee and so I now needed change the location of these Junction Boxes from where I had originally asked Dale to position them. Not a big deal and I always welcome any chance to get “up close and personal” with every bit of kit on Möbius as I’m also the guy that needs to maintain everything and keep us up an running at all times in all conditions.
The aluminium Junction Boxes are bolted to the steel housing and to reposition them I needed to re-drill and tap (thread) four new holes for the new position.
First step was to remove the two pressed on aluminium ROTORS which have all the permanent magnets embedded in them and rotate around a few millimeters away from the stationary Stator coils you see here.
With the Non-Drive end Rotor off I could now remove the Rotor on the Drive end by pressing out it and its shaft from the internal hub and bearings inside the case.
This close up of the inside of the AL Rotor let’s you see how all the permanent magnets such as the two I’m pointing at here, are embedded into the AL Rotor.
I know this is riveting Show & Tell for so many of you, NOT! but the disassembly goes pretty quickly from here so I’ll speed through the process even faster for you from here.
Top Lid comes off the Junction Box enabling me to disconnect all the wires from their studs in the sides of the Junction Box body.
Each set of Stator windings, one at each end, can now be unbolted and …….
…… pulled off of their tight fit to the central hub inside the housing allowing me to now carefully pull the three large gauge solid copper wires and terminals out through the holes in the housing one at a time.
One end Stator windings removed, ready to spin around and do the same to remove the Stator windings on the other end.
Removing 4 Allen head bolts, one seen in the bottom Right here, let’s me remove each Junction Box.
Full dis-assembled now!
Possibly resembling Dr. Frankenstein’s workbench I am already LOVING my new Workshop and all 11 meters of workbenches!
I marked the new location of the Junction Boxes with felt pen and so now it was a simple matter of lining up the 2 holes in the bottom of the Junction Box with the new holes in the housing and clamping them in position. I could then use the 4 bolt holes in the Junction Box as a template to mark the corresponding center marks to drill into the housing.
I had carefully taped off all access to the inside of the housing to prevent any metal chips or dust from getting inside and it was a bit tricky to drill the 4 holes into the housing at this angle but it worked out fine and I could then cut the 10-32 threads into the housing with my tap set.
And now re-attach the Junction Box in its new permanent location on the housing with the 4 Allen head bolts you see here in each corner of the Junction Box.
The trickiest part of the reassembly was fishing the thick stiff solid copper wires back through the hole in the Junction Box and housing as they just barely have enough room to fit through and the hole is behind the Stator windings, but it all went smoothly and I soon had all 6 Stator wires and both Field Wires all back in place and ready to connect to their awaiting studs in the sides of the Junction Box
One done; one to go!
But I need to wait to mount the Junction Box on the lower Big Red #2 on the side of Mr. Gee as you saw above because I need to strap it in first and THEN I can bolt the Junction Box to the housing OVER TOP of the strap.
As you can see, all my trial and fit had made a bit of a mess so I needed to put back some of the Beauty into these two Beasts with a good sanding and repainting.
I just happened to have this short little Jack Shaft left over from another project and in a lovely stroke of synchronicity it worked out to be the Goldilocks solution to drive Big Red #2 from the gear driven PTO on Mr. Gee. So it needed a matching paint job as well.
With all the openings and AL rotors all plugged and masked off it didn’t take me long to shoot these with three coats of Red International “Perfection” epoxy.
Although it was not the ideal shade of Red, a bit on the orangey side ….
…… they definately looked better than when I started and were now all ready to be installed onto Mr. Gee.
Hopefully Dale and all his team at Electrodyne will like what he sees too.
Now let’s quickly get onto the mounting of Big Red #2!!
I will try to mount BR#1 next week so stay tuned for more scintillating story telling then!
By now I was getting pretty quick at mounting BR#2 to the side of Mr. Gee and I wanted to do one final test fit of the Junction Box to double check that everything really did clear.
To my absolute joy and delight everything just barely cleared! Click to enlarge this photo or any other and you can see how close some of those fits are.
If you look closely you will see that there are a LOT of close fits!
I think this must be some polar opposite of Murphey’s Law where the stars align and every close fit actually cleared!
Fortunately for me, mounting Big Red #2 on that upper flat pad you saw earlier will be a breeze compared to this one and I hope to get that done next week and will show you the results.
Up at the Bow on the Anchor Deck, we needed to install this latest bit of boat jewellery; our gleaming solid SS Lewmar 13mm Chain Stopper!
It is a very simple system that can become eXtremely critical if your snubber line breaks in a big storm and you need to have a way to “for sure” hold your anchor chain to the boat no matter what. Yes, ask me how I know!
Uğur and I quickly sketched up the design we thought would work best to solidly bolt this Chain Stopper to the deck framing and he had it all fabricated out of 20mm / 3/4” AL plate and was welding it to the Anchor Deck plate.
Simple arched platform that elevates the Chain Stopper to be at the correct height of the chain as it comes off the gypsy chainwheel on the Maxwell VWC 4000 windlass and then the Chain Stopper is through bolted with 4 M16 SS bolts and nuts.
A bit of Blue Threadlocker to make sure these never come loose but are still easy enough to unbolt if ever needed.
One more “little but important” job done and checked off the list.
Hilmi was a welcome addition back on Team Möbius this week and he was right into the same theme of completing many more of those little but important electrical jobs.
He started with this one; putting in the connections for Mr. Gee’s two G31 FireFly Carbon Foam starter batteries.
First Hilmi mounted the Red Start Battery Shut Off Switch and ran the cables from there to the Battery Box locations.
Each battery will be enclosed in it’s own dedicated plastic battery box and mounted at the very far end of the Stbd/Right side wing of the Workshop underneath the Day Tank and up against the WT Bulkhead there.
They go forward another 40cm/16” from here and their lids just clear the 127mm/5” rubber exhaust hose that runs overtop of them.
Now time to tame all these electrical snakes slithering out of the Engine Room!
One of the best features of our decision to put in a dedicated Engine Room enclosure is that we can keep this an “Engine only” Engine Room and locate almost everything else OUTSIDE the ER where they are much cooler, easier to access, less likely to be exposed in the case of fire and much easier to comply with all the ABYC and CE fire safety requirements.
No batteries, no electronics, no fuel filters or tanks; nothing but Mr. Gee and his immediate systems such as heat exchangers and exhaust.
What wires we do need to bring inside the ER, mostly for the Electrodyne alternators, come through this one penetration under the floor of the same Stbd wing of the Workshop on the other side of this photo.
Hilmi takes it all in stride as usual and he, Ramadan and Cihan soon have the new cable trays in place ……
…… and start routing and fastening the cables in place alongside …….
……. and then under Mr. Gee.
Cihan does EXHAUSTING WORK!
Möbius’ Engine Room was a busy place this week as Cihan and Ramadan installed the Halyard Exhaust System which has been patiently waiting its turn down on the shop floor underneath Möbius for many months now.
As you might have noticed in some of the photos above, I had already installed the flexible SS woven mesh that bolts vertically to the aft end of Mr. Gee’s exhaust manifold.
So the fist part of the “dry” section of the Halyard Exhaust components to go in was the75mm/ 3” ID vertical SS riser you see here rising up here in the lower Right corner.
The two “wings” on this riser are where the two support rods will connect down to Mr. Gee to help stabilise them.
My personal favorite bit of kit from Halyard is this beautifully crafted and polished SS water injection elbow which Cihan is assembling to its silicone bellows.
Peering down for an inside view, you can see how the water jets are all distributed evenly around the inner circumference and make sure there is a very even spray and mixing of the seawater that is pumped through them with the exhaust gases exiting Mr. Gee.
This is where the exhaust changes from dry to wet and where most of the noise and the heat is removed by the mixing of the seawater and the exhaust gases.
Simple job now for Cihan to slide the soaped up silicone bellows to the awaiting downward angled 127mm / 5” pipe on the Halyard “Combi” Silencer/Separator that has previously been mounted on its dedicated shelf on the front ER WT Bulkhead wall.
Almost a year ago now, Yigit and I had spent several months working with Oliver and his team of engineers at Halyard HQ in the UK to design this Goldilocks Exhaust System for XPM78-01 Möbius. Together we exchanged countless 3D models that we were each creating and so it was wonderful to see this all fall into place like an accurately cut jig saw puzzle.
Even Cihan, who has installed countless exhaust systems in the many other yachts he has worked on was very impressed and asked “How did you DO that??!!”
With everything dry fitted and checked Cihan and Ramadan could now tighten up all the connecting bolts and SS hose clamps.
Using plenty of Tef-Gel on all threads of course!
All that remained to be done was install the three rubber hoses needed to complete this Goldilocks exhaust system. Over on the far Left side is the Black 75mm/3” ID hose that quickly takes all the seawater in the bottom of the Silencer/Separator down to the dedicated AL pipe welded into the exiting Sea Chest and out to sea.
Next over to the Right is the White hose that delivers the fresh cold seawater up to the inlet pipe on that SS mixing elbow.
And then the large 127mm/5” ID Black hose transports the now cool and quiet exhaust gases from the Combi down and over to the AL pipe welded into the Stbd ER wall where it then connects to another short length of the same rubber exhaust hose and out the similarly welded in place AL exhaust exit pipe in the hull just above the WL.
DIVINE DINETTE TABLE & PEDESTAL SYSTEM:
Last I have time to cover in this week’s Show & Tell is yet another bit of boat jewellery and Rosewood; our Dinette Table!
It was love at first sight for me about 2 years ago when I first spotted this Triton Deluxe 2-stage table pedestal at the Zwaardvis booth at the big METS Marine Trade conference every year (except this one of course) in Amsterdam.
This is the fully lowered position which lowers the surface of the table to be flush with the surrounding seats where it can then become an additional Queen bed on those rare occasions when we have more quests, or more likely more Grandkids aboard than can be accommodated in the 2 beds in the Guest Cabin.
Simply rotate those 2 SS handles and the air assist gas cylinder inside pushes the pedestal up to proper eating/working table height.
But WAIT! There’s MORE!
Check out that Kissin’ Cousin from Zwaardvis sitting to the side of the Triton pedestal!
This is the Triton T-System X-Move slider which allows you to slide the table top 200mm / 8” in the X or Y, Fore/Aft or Left/Right direction
by simply pulling this lever which mounts under the table. In the normal “fixed” position that little rectangular rubber pad on the Right is pressed up against the underside of the table and locks the table in whatever position you want. Pulling the hand pulls the rubber down allowing you to push/pull the table wherever you want and then release the lever to lock in that position. Brilliant!
Over in the Cabinetry shop Ramadan #2, our newest Cabinetmaker has been busy building the Dinette Table top I designed. Very simple and sturdy, it has 50mm/2” thick solid Ro$ewood edges surrounding a Rosewood laminated plywood table top.
Ramadan cut this hardboard template so we could try it in place in the Dinette on the Triton pedestal and slider and check out the clearances with the table in all its different X, Y and Z positions.
Once we had it just right, he was able to laminate both sides of some 20mm/ 3/4” marine plywood …..
……. with Rosewood veneer in the lovely heated laminating press they have here at Naval.
Mitre all the corners of the solid edging.
Cut the biscuit joints and the glue and clamp it all ….
to create a single solid table top.
All ready to have the large radii shaped into all these solid edges, sanding, filling and varnishing and I will soon be able to show you this next bit of beautiful art work aboard the good ship Möbius.
Well as usual I have much more to show you but I’m pooped, swollen and hungry as it is now after 21:00 here in Antalya on Sunday night so I’m going to call it quits for tonight and be back with much more next week.
Thanks SO much for taking time to get this far and join us on this grand adventure. As always we REALLY appreciate you adding any and all comments and questions in the “Join the Discussion” box below so don’t be bashful now! Your feedback is invaluable and VERY much appreciated.
Hope to see you here again next week.
