The Aqueous Phase of the Build – XPM78-01 Möbius 22-27 Feb, 2021

A VERY busy week here onboard the Good Ship Möbius as everyone on Team Möbius moves into the final stage of the build completing all the installations of equipment and beginning the commissioning of all these systems by their factory representatives and others.  Due to a major reconstruction project of the harbour inside the Free Zone * which removed all the previous launching facilities, Naval needed to launch us quite a bit sooner than expected by transporting Möbius overland to the nearby Setur Marina.  So in addition to the usual post launch commissioning of systems, we all continue to work our way through the Punch List of jobs needing to be completed in order to get Möbius into seaworthy condition to begin taking her out for sea trials.  To say that we are all eXtremely busy would be the understatement of the year!  But. for Christine and me, we are even more eXtremely eXcited to be back where we belong, home onboard a boat that floats.

* You can learn all about this huge and fascinating project by watching THIS VIDEO ANIMATION which does a great job of showing how the whole new harbour facility will work.

I hope you will accept my apologies in advance for another hurried weekly Möbius Update as I blast through as much of all the different jobs that we have all worked on this past week.  So grab your favorite beverage and chair and join me for this week’s Show & Tell.

Let me start with a quick snapshot leading up to this adventure that began over 5 years ago.


Mobius front Stbd render

After two years of intense collaborative design work with our AbFab Naval Architect Dennis at Artnautica Yacht Design, the building of XPM78-01 Möbius began at Naval Yachts on April 6, 2018. 
Launching Stbd side from Dincer1053 days of build time later, as most of you have likely seen in last week’s posting HERE, she finally left that temporary womb last Friday for a watery delivery into her permanent home with Mother Ocean last Saturday. 
PXL_20210222_081251718As I write this blog post from the SkyBridge of our beloved Möbius, we have just finished our first week afloat tied up to the concrete dock wall inside the Antalya Free Zone Harbour. 

And I am VERY happy, though not surprised, to report that ALL the sea water has remained where it belongs OUTSIDE of Möbius and our bilges only hold the remnants of construction dust and debris.

DOCKSIDE NEIGHBORS

PXL_20210222_081426614

Looking all the world to me like two tugs that escaped from a children’s animation story, these two almost new tugs are our most immediate neighbors.
PXL_20210223_125007789.MPTied up less than a meter in front of Möbius’ Bow.
PXL_20210227_065047889

These two tugs have crew aboard 24/7 as they are responsible for bringing every cargo ship into and out of the commercial side of the Harbour such as this recent little visitor, the 180m 36k Ton Argo B, who left about 04:30 this morning after loading up with several thousand “Big Bags” of industrial dry goods.
PXL_20210225_063350261These two tugs are also the Fire Boats for the Harbour.  And last night, they surprised and delighted us by bringing over a home made pizza just out of their oven!  Can’t think of a better example of why we LOVE living with these awemazing people of Turkey.
PXL_20210222_084755831.MPTied up almost as closely to our Stern is this first of four Police boats which are being built by Ares Yachts here in the Free Zone for the government of Oman.  These are a bit longer than us at about 26m but share many of the same basic attributes as our XPM-78 with all aluminum construction and built like the proverbial tank.
PXL_20210225_064345248We even have the same jet propulsion system though in our case just with our Tender and a single not these massive twin jet drives driven by two equally massive MAN diesel engines.
PXL_20210226_102842036One item that we do not share, YET! with these boats is that mount for a 50 cal machine gun.  But rest assured that once I get my 3D printer setup one of my first projects will be to create a realistic enough looking plastic replica to produce a silhouette that will add to our “don’t mess with me!” look to any onlookers thinking of approaching us with mal intent!
PXL_20210228_064153289I took this shot of our neighborhood early this morning after the Argo B had left and the tugs were back in front of us.  The weather has been truly spectacular for the past two weeks with daytime highs reaching 24C/77F and gloriously sunny clear blue skies with very little wind.  Not a bad place to spend our first week afloat.

For safety of such a new and incomplete boat, Christine and I are sleeping aboard each night and then going back to our apartment for breakfast and dinner and then we will move aboard full time once all the sea trials are done.

ANCHOR AWEIGH!

Bow render w anchor no railsOne of the projects I did not have enough time to show you last week was the completion of our rather unique “Sidewinder” anchor roller assembly that Dennis and I came up with so let me show that to you now.
150 Anchor Roller dim dwg v3I decided to make the two anchor rollers out of solid aluminium and didn’t take me long to design a 3D model of this in Autodesk Fusion 360 and create the 2D dimensioned drawings to machine them from.
PXL_20210210_133511164Aluminium is a dream to work with and the in house machine shop has a very good sized lathe that was easily able to machine the two anchor rollers out of a single blank of 200mm/8” OD aluminium round stock.
PXL_20210215_101708879I wanted to keep the anchor and the chain electrically isolated from the hull to reduce any corrosion problems and was able to do so with two details.  One is this Black Delrin bushing which we press fit into each roller with a nice rolling fit for the 40mm/1.6” SS pin that each roller spins on.
PXL_20210215_101554236The second isolating detail was to machine these Teflon discs that get separate the sides of the rollers from the inside cheeks of the anchor roller assembly welded into the hull.  Then a large SS end cap bolts on either end of the SS pin on the outside.
PXL_20210217_111230847Here is what that all looks like when assembled.
PXL_20210216_121707878For safety and quiet when pounding into big seas we very specifically designed the whole roller assembly to exactly match the shape of this 125kg/275lb Rocna anchor by obtaining a 3D model from Rocna to design with.  The way our design works is that those flared out bottom edges you see in the photo above have been designed such that they exactly match up with the inside of the flukes of the Rocna when pulled aboard and thus the Rocna becomes one with the hull and will not budge no matter what Mother Nature throws at us.  This creates not only a very tough and strong anchor mounting setup but also one that does not make any noise due to movement between the anchor and the roller assembly which is so common on many other boats we have run.
PXL_20210217_111212651So Nihat, Uğur and I spent quite a few hours with the anchor raised on a chain block that allowed us to get the position of the anchor just right and then layout the centers for each SS roller pin.  Front pin and roller have been mounted here and we are laying out the location for the 2nd Aft roller.
PXL_20210217_112203638Uğur and I came up with this idea of building an extended 40mm carbide hole saw so that he could drill both cheeks in one go and keep the two holes for the SS roller pin on the same centerline.  We lucked out finding the head of a 40mm carbide hole saw with its shank broken off and Uğur TIG welded a 200mm/8” long piece of 13mm/ 1/2” OD rod to it that we could chuck in my Milwaukee drill.  Worked like a charm!
PXL_20210217_134123280.MPWith the rollers both installed we tested it all out with the 13mm / 1/2” chain and the Maxwell VWC4000 Windlass and did a bit of tweaking of the rollers final shape to capture the chain nicely so it stays aligned as the chain goes Out/In and doesn’t twist. 
PXL_20210218_130220400Did not take us long to get to the Goldilocks Just Right point
PXL_20210219_063440982.MPand “Rocky” was in his new home as solid as his name.
PXL_20210217_151007235.MPUğur and Nihat both gave it their thumbs up and so we knew it was good to go!

BOTTOMS UP!

Another job and details I did not have time to post last week prior to the launch was the finishing of the silicone based International InterSleek 1100SR Foul Release bottom paint and the zinc anodes so let me go back and show you that.

PXL_20210215_101207324Once the super slick, slippery and shiny silicone InterSleek was fully dry the last few underwater details could be attended to such as mounting the Red plastic prop on the Vetus 220kgf 300mm/12” Extended Run Time Bow Thruster.
PXL_20210215_101145530Which is capped off with its own Zinc to reduce any problems with corrosion due to the mix of dissimilar metals involved with its construction of Bronze, SS and AL.
PXL_20210216_111830409.MPIn keeping with our Darth Vader, lean & mean look, we decided to make the 100mm/4” Boot Stripe that makes the transition between the top of the Black InterSleek and the bare AL hull, be gloss Black as well and we are eXtremely happy with the result that emerged as the masking tape came off to reveal the final look.
PXL_20210216_121054898The final detail for the underwater portion of the hull was mounting the ten 125mm / 5” diameter Zinc anodes which keeps all the metal bits that are in contact with seawater all at the same potential voltage and eliminates the battery effect that would eat away at our precious Stainless Steel, AL and Bronze components. 
PXL_20210216_121611273Being near the bottom of the Noble scale of metals, Zinc is what will erode instead and makes it easy to replace the zincs every few years when they get too worn away.
PXL_20210216_121418621.MPWe designed a very simple mounting system for the Zincs and Uğur had previously welded 80mm discs of 20mm / 3/4” thick AL to the hull with an M16 thread in the center for the SS M16 bolt that he is fastening this Zinc on the Rudder with.
PXL_20210219_063321360To ensure a good electrical connection for many years between the Zinc and the AL mounting disc, we coated those surfaces and the bolt with dielectric grease and then I followed along after Uğur and covered the SS bolt heads with some clear silicone to make it all the easier to remove and replace these zincs in a couple of years.  I usually do this while the boat is in the water using my Hookah or Snuba system so these little details all help to make that job go quick and easy.
PXL_20210219_063354149With all these preparations of the below the waterline areas of the hull and everything removed from underneath, Möbius was ready for the arrival of “Big Bird” the yellow 72 wheel boat mover to arrive the next morning and carry her overland to the marina for launching.

TILLER ARM DETAILS:


Tiller Arm w cylindersAnother few details that we needed to look after before Launch Day were for the all important steering system and the Tiller Arm in particular.  Similar to the Bow Rollers, last year I had designed this typically over engineered Tiller Arm in Fusion 360 and had it CNC milled out of a single block of aluminum.
Tiller Arm being fittedHere is a shot from almost a year ago when we first mounted the finished Tiller Arm to the 127mm / 5” OD solid AL Rudder Post.
PXL_20210118_151755877And here is a more recent shot of what it looks like with the two double acting Kobelt hydraulic steering cylinders in place.
PXL_20210215_143337875Such a massive Tiller Arm being powered by equally as beefy twin hydraulic cylinders, produces a LOT of force and so there needs to be some eXtremely strong and solid Tiller Arm Stops built in to stop the Tiller Arm when it goes hard over to each side.  Fusion 360 to the rescue yet again to help me quickly design these Stops which Uğur and Nihat quickly fabricated and were ready to mount.
PXL_20210215_153108831After carefully testing out the Just Right position for each stop, they were able to drill the four holes in the AL Rudder Shelf and bolt down one Stop in either side of the Tiller Arm body.  The SS bolt and lock nut allow us to adjust the final Stop position of the Tiller Arm once we are in the water and have the steering all working.
PXL_20210118_134133102I like to practice and live well by what I call “Readiness for the UneXpected” and in the case of our steering system that meant having multiple layers of fault tolerance for the Steering System.  This starts with twin independent Kobelt 7080 hydraulic steering cylinders sized so that either one can fully steer the boat in the most adverse sea conditions.

Then two independent Kobelt Accu-Steer HPU400 24V hydraulic Power Pack pumps, two independent Furuno 711C AutoPilots plus two independent Furuno Jog Levers.  This gives us eight levels of fault tolerance to go through.



PXL_20210226_121100138And if ALL of that should uneXpectedly fail, then we have this Kobelt manual hydraulic Steering Pump ……………
PXL_20210225_140913191.MP ……….. that we can slide this Emergency Steering wheel onto and steer the boat the “old fashioned” way.
PXL_20210121_080012586.MPAnd if ALL of that should somehow uneXpectedly fail we have THIS final layer of fault tolerance for our steering system; a completely independent and manual Emergency Tiller Arm.
PXL_20210118_134143252Can’t get too much more KISSS or Keep It Simple Smart & Safe than this; a 2m/6.5ft length of 80mm thick walled AL pipe that slides through the 20mm/ 3/4” thick plate we see Uğur bolting to the Tiller Arm body and then the pipe slides through a matching hole bored through the top of the Rudder Post. 
PXL_20210121_080012586.MPWe attach a block and tackle setup on each side of the end of the Emergency Tiller which fasten to shackles mounted on stringers on the adjacent hull sides which allows us to move and lock the Rudder in any position we want.

Yes, I do know that it works and Yes, you can ask me how I know that!

Miscellaneous Work on Deck

Finishing up this blog post is between me and another very late dinner so I’m going to speed through a series of other jobs that got done this first week in the water.
PXL_20210215_131834473Turkish Turquoise Marble countertops got installed atop both Vent Boxes on the Aft Deck to create our Outdoor Galley.
PXL_20210215_131519658.MPSS sink plumbed.
PXL_20210215_085612478And installed in the Starboard/Right side Vent Box.
PXL_20210215_131927886Plumbing connections all ready to connect to the sink; Red & Blue PEX lines with shut off valves for the Hot/Cold water to the sink faucet, Brass elbow for the sink’s drain and small Blue tube with the Black elbow to drain the water extracted by the Mist Eliminator grills in the Engine Room supply air duct.
PXL_20210216_105438835.MPOrhan with his home made adaptor for his pneumatic caulking gun ……..
PXL_20210216_122129530…….  to get into some hard to reach spots around the Pilot House windows like these.
PXL_20210218_134142509Uğur prepping the nylon insert mounts for the Passarella on the Swim Platform and another on the Port side gate.
PXL_20210226_122256916Ever the ingenious one on Team ,Uğur came up with this brilliant DIY solution for mounting our Fire Hose in the HazMat Locker; an empty plastic spool of MIG welder wire!

PXL_20210226_122310591Which will rotate on this pipe mounted on the side of the HazMat Locker.
PXL_20210227_133714661With the Black Fire Nozzle mounted alongside.  Any wonder why I just love working with this guy who has been with us from the very first day of the build?!!!
PXL_20210227_110021249More Uğur Goodness, on Saturday no less, as we designed and built this simple setup for propping the front 3 Solar Panels mounted on this hinged frame up in the horizontal position when we are on anchor.

This horizontal position not only helps out with solar power production but you can see the demister grill across the far end of what now becomes a giant wind tunnel to capture all the fresh breezes blowing over our bow at anchor and funnel them down into the SuperSalon.
PXL_20210227_105959889Two SS pipes that are hinged to the bottom of the Solar Panel frame and will fit into these Black Delrin collars Uğur machined which were then glued down to the aluminium floor with a SS set screw to lock them in place.

When we are ready to convert to passage making mode and head out to sea, you simply lift the panels up a few inches and the two support rods slide aft as the panel is lowered down and locked into place.

ELECTRIAL WORKS:

Our Sparkie Hilmi always has a long list of electrical jobs that need his attention and this past week was certainly no exception.  With almost 150 circuit breakers on XPM78-01 Möbius to safely look after all our 12 & 24 Volt DC circuits and our all our 120V & 240V AC circuits, it was quite the design challenge to figure out where and how to place all these.

PXL_20210226_085403482We ended up with two primary circuit breaker panels; this one on the angled short wall on the Stbd/Right side of the Main Helm Station.
PXL_20210226_085300787.PORTRAITAnd this larger one in the Corridor at the bottom of the stairs leading down from the SuperSalon to the Guest Cabin, Ships Office and Workshop/Engine Room.
PXL_20210226_085119437After months and months of preparation, Hilmi was finally able to bring it all together this past week by attaching these Black AL panel fronts with all the engraved labels onto the hinged access doors into each of these Circuit Breaker panels.

Next week the hinged glass doors are due to arrive which will finish off these critical component of the electrical system on Möbius.

GLASS WORK

PXL_20210224_133202907.MPThe double paned 16mm thick glass window finally got installed in the Engine Room door this week which is a critical component to completely closing in the Engine Room in the case of a fire.
PXL_20210224_083947825.MPAnd the gas lift cylinders have now all been installed on the Glass Deck Hatches which I designed and Naval built in house.  Now just need to finish installing the rubber edge seals and the AL hatch handles and the deck is totally watertight!

HELM STATIONS:

PXL_20210217_125040209I can’t possibly do justice to explain the amount of work that Christine has done this past week alone on getting all our navigation and electronics in both Helm Stations all setup and working. 

Nor can I articulate how much I LOVE my Captain!
PXL_20210228_064153289What I can do though is to leave you with this shot from early this morning that does capture for me just how well we have succeeded in designing and building our new home with all of Team Möbius to meet the goal we set out over 5 years ago to blend in perfectly when in a commercial dock as apposed to a ‘yachty’ marina.
And with that I am going to hit the “Publish” button on this latest Möbius Weekly Progress Update and look forward to bringing you more Show & Tell of this coming week’s progress that begins first thing tomorrow morning.

But WAIT!!!

There’s MORE!!!!!

One year ago, Christine and I returned from a brief trip over to the UK for her Birthday (March 15th) just as the whole Corona 19 pandemic was ramping up and caught us squarely in the vortex.  Given our ages, let’s just say rapidly approaching 70, every day since we have been playing a kind of Russian Roulette by going into the shipyard to work on Möbius and so we are eXtremely eXcited that tomorrow morning at 11am we are going to get our Covid 19 vaccine shots!

Of course, this doesn’t put an end to anything really but sure will help with our upcoming travel plans, for which we shall be eternally grateful to this country we have called home for almost four years now and that love a wee bit more every day.  Thank you Turkey for allowing these two salt water turkies to enjoy your beautiful country and people!

What Dance Step Rhymes with Ca$h? XPM78-01 Möbius Update 19-20 Feb. 2021

Team Möbius continue to rack up the milestones and this week we hit the jackpot that inspired the riddle in the title of this post; What dance step rhymes with Cash (and LOTS of it!)


PXL_20210219_063644228.MPDoes this photo taken on Thursday afternoon give you some clues?

Hint: Something is missing?
PXL_20210219_063714754[7]How about this one?

Hint:  Opening door?
PXL_20210219_101408620.MPStill not sure? 

Hint: What just appeared underneath?
PXL_20210219_101428023.MPBingo!  “Big Bird” the 72 Wheel Yellow Boat Mover has arrived at Naval Yachts because ……………..

LAUNCH DAY HAS ARRIVED!!

Don’t worry if you have not yet solved the riddle as to what dance step rhymes with “Cash”, hang in there and all will be revealed and be clear by the end.


PXL_20210219_101511656All the big shipyard doors are opened up full width and Big Bird slides under the all cleared out space (the “what’s missing?” hint above) below Möbius and the countdown to launch begins!
PXL_20210219_101601088Captain Christine is up on Deck doing last minute prep and clean up and the Owner’s Rep is standing around as usual, getting up close and personal with Big Bird.
PXL_20210219_101631581All the while Möbius is being her typical good natured and patient self as she awaits the her big moment to shine in the brilliant sunny day we were gifted with for the big launch.
PXL_20210219_101500582You may recall from previous moves over the years, Big Bird has a series of swiveling hydraulic lift pads along both sides
PXL_20210219_101754093So they are now being readied to lift our girl off her support stands and struts for one last time.  Or so we thought at this stage of the “dance”, stay tuned for more on that.
PXL_20210219_103314818.MPThe silicone InterSleek 1100SR bottom paint is quite soft and new so they cut up squares of carpeting
PXL_20210219_103424419.MP….. and slid them in between the hull and the wood lift pads to prevent the rough wood faces of the hydraulic lift pads from damaging this fresh paint.
PXL_20210219_105810417.MPWith all the Lift Pads in position 20 hydraulic pistons easily lift Miss Möbius up off her perch and all the support stands underneath can finally be removed for good.
PXL_20210219_110321990.MPThe Captain does one final check and packs her bag with cameras and champagne and is ready for the long and winding walk to the temporary new launch site that is much further away as you are about to see.
PXL_20210219_101700376The BIG Day has finally arrived and Möbius takes her first step away from her home of the past 3 years at Naval Yachts and heads for her new home; Mother Ocean.
PXL_20210219_110932901You can almost hear the shipyard and all the other boats saying “Good Luck Miss Möbius, we’ll miss you!” as she makes the turn onto the road that leads over to the inner harbour inside the Antalya Free Zone.
PXL_20210219_111038783She graciously poses in front of the home she is about to leave as she heads out to make her own life at sea eXploring that Big Beautiful World of Water that awaits.

Oh, the places you will go Miss Möbius!!


PXL_20210219_111148707.MPThree of the pivotal people responsible for building Möbius join in the Big walk.
PXL_20210219_111213341And Möbius’ adopted parents join the parade as well.
PXL_20210219_112722712Rounding the first of several sharp corners is a piece of cake for Big Bird when you have 72 wheels that can all steer!
PXL_20210219_112935868This massive construction of the whole inner harbour of the Free Zone which has ripped out all the launching facilities and necessitated that we take an overland route to Setur Marina and launch all the boats from the Free Zone shipyards there for the next few months.
In spite of this major disruption this major construction project of the whole Free Zone port is fascinating and you would probably enjoy watching THIS VIDEO ANIMATION which does a great job of showing how the whole new harbour facility works.


PXL_20210219_113015350It would normally be quite a shock and surprise to see a ship floating by outside your office window but here in the Antalya Free Zone it is a common and almost everyday occurrence so no one gives it much mind.  However, given the uniqueness of the XPM boats and Möbius’ gleaming aluminium silver sides, she definately turned a LOT of heads on her trip to the sea.
PXL_20210219_114622008.MPNormally this is where the Free Zone ends and there is a very large and intimidating gate here topped with concertina wires and lots of security cams but we were given special permission and so they opened up the gate, took down lots of big power cables above and we rolled on through.
PXL_20210219_115719585We took this rare opportunity to do what you are supposed to do with all newly born creatures and introduce them to as many of the other inhabitants of the brave new world they have just arrived in. 

Not a bad backdrop!
PXL_20210219_120101851One more 90 degree corner which was no problem for us but ……….
PXL_20210219_120324668….. startled a few of the truck, car and bus drivers who suddenly found themselves sharing the road with a 24 meter / 78 foot long boat!

Not your average traffic jam!
PXL_20210219_122831308The long and winding road trip eventually led us to this road on the back side of the repair yard section of Setur Marina and the final 90 degree turn to the home stretch to the new launch site.
PXL_20210219_123231016Uğur, who has been with us the longest is particularly happy to see this big day finally arrive, took the opportunity to climb aboard and have his own scene right out of the movie Titanic perched up at the bow as he rode the final land based home stretch.
PXL_20210219_124031302We’ve arrived!

Big Bird rolls to a stop right in front of …..,,
PXL_20210219_123431996…… Möbius’ very handsome date who has been patiently awaiting her arrival.
PXL_20210219_124102442Like walking the Bride down the isle, Big Bird carefully escorts Möbius down the path underneath the turquoise arches of this 200 Ton Travel Lift.
PXL_20210219_124735189There are four of these cabled lift points on each side of the Travel Lift which are now carefully lowered to the ground.
PXL_20210219_125449159Where the looped ends of the thick wide webbing that forms a sling that goes underneath Möbius belly, are pinned to the lift bars.
PXL_20210219_125459953To protect Möbius’ fresh silicone Foul Release bottom paint, the slings have all been covered with soft padding.
PXL_20210219_131147586.MPAnd then each sling is threaded overtop of Big Bird’s side rails, under Möbius’ belly and connected up to the lift bar on the opposite side.
PXL_20210219_131648718.MPUp go the lifting slings as the weight transfers from Big Bird’s lift pads and they can now all be removed.
PXL_20210219_132811906Transfer complete!  Big Bird backs out and heads back to the barn while the Travel Lift carries Möbius ……..
PXL_20210219_133106152……. the final few meters to the water’s edge.
Sccreeeeeeeechhhhhh!!!!!!  HOLD IT!!!

Not so fast there Miss Möbius, there are official vows and a ceremony needing to take place before you get your first taste of Mother Ocean’s tasty salt water!
PXL_20210219_133835446Travel Lift obliges and backs up just enough for Christine, Baris and myself to say a few words, announce that “We christen you Möbius” and break that champagne bottle over her hefty keel bar.

Note to those concerned, Christine had carefully wrapped the champagne bottle in silicone mesh so no glass shards were spilled.

The not recorded funny part is that this took two tries as the thick glass of the champagne bottle won the first smash on the keel bar and took this second try which you can see in THIS short video clip which I have also embedded below.


But here at last is Möbius first kiss with Mother Ocean.

Oooooops!  Not so fast there Captain!  Mr. Murphy has different plans for you today! 

Immediately upon splashing into the water and while still in the slings, you spend a few minutes below checking all through hulls and other possible sources of leaks to make sure that everything is sealed and all the salt water is where it is supposed to be; OUTSIDE the boat!  As we did so we found a small leak on the Rudder Shaft tube and so we made the call to haul her back out and set her back on land while we tracked down and fixed the leak.  Hence the less than excited faces on all of us in the video below as came back out of the water and onto the hard for the night.

PXL_20210219_153551925.MPPoor Möbius!  So close yet so far and yet another example of that paradox of trying to get to your destination by taking steps that are half the distance remaining which means that you get closer and closer but never fully arrive!

The Travel Lift set us back down in front of the launch pad and she was once again blocked up for the night.
Later that evening I discovered the source of this leak which fortunately this turned out to be a set of 6 holes that had been drilled into the Rudder tube for injecting Sikaflex around the outer races when they were installing the Jefa Rudder roller bearings for the Rudder Shaft.  This happened back in October 2019 while I was back in the US and Canada visiting family so I wasn’t aware of this procedure and the SS plugs had not been threaded into these holes so they were weeping upon entry into the water.  A relatively quick and easy fix and I re-tapped/threaded these 6 holes to clean out the threads thoroughly, Uğur & Nihat ran into town to get six M12 x 10mm SS socket head bolts and I mixed up a batch of good ole’ JB Weld to fill the holes and coat the threads and torqued the 6 bolts up tight and we were done before 10pm. 

PXL_20210220_074131074!Next morning, Saturday 20 Feb, 2021 we arose to what was surely the perfect Launch Day with even more sunny and brilliantly Blue skies and NO wind
PXL_20210220_075833752And it was time to back the Travel Lift overtop of us and put those slings back underneath to lift us up and take us those final 10 meters to the water’s edge!
PXL_20210220_080053999Lowering back down so Möbius could have here second kiss with Moher Ocean.
PXL_20210220_080424001Once in we again checked throughout the boat for any sign of seawater inside such as around this Sea Chest in the Forepeak and my first glimpse of the sea below.
PXL_20210220_081132208Not a drop to be found onboard so a quick check of where the real waterline ended up at the stern and we were good to cast off and be gone.
PXL_20210220_080913580We gave the thumbs up to the Travel Lift operator and the slings were fully lowered and he backed away.
PXL_20210220_081835728.MPDue to several complications Möbius did not have a working steering system and the oil for the Nogva CPP gearbox has still not arrived but all the arrangements for getting out of the Free Zone, taking down the power lines, Travel Lift apointment, etc. had been made long in advance so we launched anyway and that meant we had to be towed back to the harbour inside the Free Zone which is why this tug showed up and threw us this line.
PXL_20210220_081903654Fortunately we had thought of these kinds of scenarios well in advance and had designed this Samson post and nose cone for just this purpose and the tow rope was quickly set and we were off.
PXL_20210220_082419103.MPThe Free Zone harbour is literally around the corner that is on the Left side where that Blue & White tug is tied up so it was a very quick trip and with no wind it all worked out just perfectly.  The large green boat in the center is inside the Free Zone which then becomes the container port on the Right with all the cranes.
PXL_20210220_082843978Rounding that corner on the Left with the Green boat now off on our Starboard side to the Right we can see the slot they have opened up for us to tie up in between the end of the Red tugboat on the Left and the Grey bow of the first of four Arabian Police boats you can see lined up along the same wall.
PXL_20210220_083127851Naval had arranged for a second second small tug to help maneuver the stern and push us into our slot sideways.
PXL_20210220_083200366.MPBecause as you can see, the open space was only about a meter longer than our 24 meter overall length so It was a pretty tight fit and they needed to push us in sideways to fit.
PXL_20210220_083652768With the help of some of the great guys on Bozcay IV and III, we got the first line ashore and it was all very quick and easy from there in these windless conditions.
PXL_20210220_083700813Now the second tug on our stern could push us sideways into the wall with just enough room to spare off the bow of the first Police boat.
PXL_20210220_083857222.MPViewed from up in the SkyBridge, this is Möbius’ first contact with a dock.
PXL_20210220_084817142Stern lines secured and we were soon all tied up for the first time!
PXL_20210220_114210047When Christine and I were first drawing up our design criteria and use cases, one of the things we wrote down was that we wanted to fit right into being docked in a working harbour and stick out like a sore thumb in a “yachty” marina. 

So how well do you think we have met that criteria with these as our neighbors astern………
PXL_20210220_114303253….. and these two up front?
PXL_20210220_091707339Still lots to do as the real work begins but enough time for a quick snack and celebration with the two founders of our builder Naval Yachts; Baris on the far Left and his brother Dincer on the right.

PXL_20210220_130739566The rest of the afternoon was equally as Goldilocks time as we enjoyed this stunningly sunny 17C/62F weather being entertained by our two new bow neighbors as they brought this little fella “Lucky Star” in to get loaded up.


PXL_20210220_122446352Then it was just the Captain and I, and of course Ruby and Barney so it was at last time to celebrate with an unbroken bottle of champagne that we had at last made it to that ever elusive Launch Date!

Peanuts, a box cutter and champagne, what could be more Goldilocks; Just Right, Just for Us?!!!
While we never doubted that we would make it we did often wonder just when this day would arrive but that has all made this milestone all the sweeter to experience.  We still have LOTS of work to do to get our beloved Möbius fully finished and ship shape so we can head out for those infinite horizons and get back to eXploring this awemazing world of ours.

Oh, almost forgot!  If you are still wondering about that riddle, it was the 2-step Splash Dance! Smile

I’ll be back to cover all of that starting with next week’s Progress Update but for now we’ll be sleeping aboard to keep an eye on this new launched beauty and start learning all she has to teach us.

Our Bottom is all Slippery Sleek Silicone Goodness! XPM78-01 Möbius Feb 8-13, 2021 Progress Update

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? 

Answer? 

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. 

PXL_20210208_112600152By 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.
PXL_20210208_112608421With 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.
PXL_20210209_093735862.MPIt 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.
PXL_20210210_092107160They 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.
PXL_20210210_092302634For 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. 
PXL_20210210_092308514Given 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.
PXL_20210210_101524098.MPIlyas is the Manager of Damen’s InterSleek team and started mixing this 3 part mix of 737 primer.
PXL_20210210_105644786.MPAs 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.
PXL_20210211_075627520.MPThis 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 ……..
PXL_20210210_105715884.MP…….. onto the hull like this.


PXL_20210210_105659644.MPAs 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!
PXL_20210210_111242641Möbius is 24m / 78 feet long on each side and yet
PXL_20210211_064820956…. it took Ilyas less than 15 minutes to spray on two thick coats on all that area!
PXL_20210210_123424936And that included details such as the Rudder and prop shaft Skeg, and …..
PXL_20210210_123532937…… the Bow Thruster Tunnel.
PXL_20210211_075559515The 737 Pink primer was allowed to set up for 24 hours and then it was time for …….
PXL_20210211_105524745…….. 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.
PXL_20210211_112117377While 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.
PXL_20210211_112133892Depth and sonar transducers……
PXL_20210211_112140333….. and deep up inside all the 5 Sea Chest tubes.
PXL_20210211_112427662InterSleek 1100SR all mixed up and suction pipe set inside so it is all systems GO!
PXL_20210211_112151546.MPDifficult to capture with the camera amongst all the fumes but that gun blasts out a cone of paint that is about 1m / 39” wide
PXL_20210211_114034525And so once again Ilyas had the first coats of Black InterSleek all sprayed on in under 15 minutes!
PXL_20210211_114121036It 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!
PXL_20210212_134412947A 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.
PXL_20210212_134453066Uğur 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!
PXL_20210212_134430757With 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.
PXL_20210212_151510356These 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.
PXL_20210213_065846684.MPAnd this.
PXL_20210213_134050998Once 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.
PXL_20210214_113347419.MPFinally, 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.
PXL_20210213_065736002.MPThis 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.

PXL_20210212_092737232This 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?!?
PXL_20210212_100551588.MPThe 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”.
PXL_20210212_104528251The 2 part yellow coloured PellerClean comes in premeasured cans which you simply stir together well for about 5 minutes and then brush on.
PXL_20210212_110903745It 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.
PXL_20210212_110931383But with each of the successive 3 coats we were able to get it well evenly applied and then let dry for 24 hours.
PXL_20210212_145340315The 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.
PXL_20210212_151442537Another 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!
PXL_20210213_065730622.MPI 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.


PXL_20210210_113853962.MPOur 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.
PXL_20210210_113920584I 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.
PXL_20210210_113928698Sinan 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!)
PXL_20210212_112358237The 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.
PXL_20210212_135937851.MPRamazan 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.
PXL_20210209_154731732Which the Captain is particularly looking forward to and testing out here.
PXL_20210212_090146782.MPJust 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.
PXL_20210212_090139258As well as these mirrors on the doors of the cabinets above the sink inside the Master Head/Bathroom.
PXL_20210212_090153000Overhead 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.
PXL_20210210_114238050From 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.
PXL_20210209_145448167We 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.
PXL_20210209_145444826Same 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.
PXL_20210211_065125892.MPThe largest front and center window in front of the Main Helm gets 3 of these vents.
PXL_20210210_093744601And all the other windows have 2 diffusers.
PXL_20210212_140108449Captain 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.
PXL_20210211_121005189We 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.
PXL_20210211_121753402We 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.
PXL_20210211_123229143The 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.
PXL_20210211_123332857First slab with the cut-out for the SS sink all glued in and ready for the 2nd piece.
PXL_20210211_123402577To be set into the SikaFlex much like how you would lay ceramic tiles. 
PXL_20210211_132235204.MPThis 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!

PXL_20210209_154420571Saving 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.
PXL_20210209_154321990.MPBarney 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.
PXL_20210209_154649602.MPAnd 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.

The Captain and Mr. Gee get CRANKY! XPM78-01 Möbius Update 01-06 Feb. 2021

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!

PXL_20210206_140841305Several 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! Smile
Gardner Chain   Direct Hand Starting exploded diagram

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. 
Old Hand Crank model 1Michael 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!
NEW hand crank illustration Plate 12 Spare Parts 702.1 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.
Front Hand Crank adaptorSecondly, 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.

Hmmmmm

Let’s just say that the front of Mr. Gee became a very busy and challenging spot for me to sort out.


PXL_20201122_095008369When 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. 
PXL_20201122_095015832It 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.
Gardner Chain Wheels dim sketchesI 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.
Gardner Front Chainwheels   timing belt pulley dim sketch colorAfter 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.
Crankshaft Chainwheel   cogged pulleys Fusion 360 renderWith 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.


PXL_20210201_150213957Oh, 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.


PXL_20210204_122850144This 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.


PXL_20210204_122908730Now 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.
PXL_20210205_140738395I 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.
PXL_20210205_140824688This 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.
PXL_20210205_141628196So 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!

PXL_20210205_141659563Oh, 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.
PXL_20210205_143910615To 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.
PXL_20210206_135651951With 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.
PXL_20210206_135637489Not 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.
PXL_20210206_140841305And to come full circle, you now understand what put that great grin on my Beautiful Bride and Captain.

INTERIOR UPDATES:

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.


PXL_20210202_125938206Ramazan 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.
PXL_20210202_125923462.MPMost 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?
PXL_20210201_111258391.MPAha! 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?
PXL_20210201_111436078.MPOf 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.
PXL_20210202_125951335This 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.
PXL_20210205_113903023While 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.
PXL_20210205_085307113.MPIn 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.

Boot Stripe:


PXL_20210202_095316082Not 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.
PXL_20210203_084950069The 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.
PXL_20210205_110308646.MPThe 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!

PXL_20210204_111609737.MPHmmmm……………..

Why is THAT truck parking beside Möbius??
PXL_20210204_111756370.MPYup!  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!
PXL_20210204_115439374It 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. 
PXL_20210204_115453633With 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.
PXL_20210204_115447196Just 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”.
PXL_20210204_115412676But 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.
PXL_20210204_115422773When 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.
PXL_20210204_115015814.MPFor 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! Winking smile

X marks the Spot!

PXL_20210206_082334595OK, are you ready for the final milestone that Christine and I just completed yesterday? 

Does this help you guess what we are up to?
PXL_20210206_082345994Helpful hint:  It took place UP here.
PXL_20210203_073143437.MPThat’s right!  Time to apply these CNC cut vinyl letters and numbers to put the XPM78-01 markings big and bold on Möbius’ Bow.
PXL_20210206_083629682.MPAll pretty simple to do.  First mark off the top edge of the lettering with a straight edge and pencil.
PXL_20210206_084701016Give 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.
PXL_20210206_093916021Peel 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. 
PXL_20210206_090548321.MPThen 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.
IMG_1067Bring in some cheap labour if you must.
PXL_20210206_094724331.MPTake your time to go over each letter and number several times.
PXL_20210206_091056342.MPThen stand back to check out the proportions and placement.

Goldilocks!!
PXL_20210206_124024008And 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!
PXL_20210206_124011267Now 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.

Thanks!
