EPISODE 134
In this episode we install the Aquadrive thrust bearing (which requires an extremely shiny and strong custom stainless steel bracket), the coupling, the stuffing box, the prop shaft, and the propeller! Our neighbour Dylan help us with lots of machining work as we cut the shaft to length, cut the keyway, face the coupling, and so on.

Machining the Driveline & installing a strange Propeller (EP134)
For those who want to know how the propeller works: There are internal gears inside the hub that engage when the boat is put into forward or reverse, so depending on the direction of shaft torque, the blades rotate to a thrusting position. With the transmission in neutral and therefore no torque on the driveshaft, the water pressure on the blades pushes them into a neutral position.
Oh neat! I get it now, good explanation!
How does it manage to generate then?
It will only feather from forward thrust. If in reverse pitch the water pressure keeps it in reverse hence the ability to re-gen. It's simply a function of an offset hinge point.
thank you
So, for enabling regen the prop needs just to be run in reverse for a short time and then begin sailing?
I'm so pleased you gave time to Dylan's machinist skill. It's such an underappreciated trade and these guys are so talented. Bravo again, Leo!
I love seeing a skilled tradesperson at work.
Have you watched cutting edge engineering Australia? If not you might likel it, a lot.
@@waterboy8999 Looks at it all the time. Amazing skills.
I saw a wire EDM (electronic discharge machine) at work in a machine shop a while back. It was kinda boring to watch it work but when I saw the finished piece I was in absolute awe. I love machine shops.
and that guy did good work!
Awesome work by Dean in Seattle on thrust bracket base, Dylan McKay on shaft and flange work, Vetus for hardware, Aqua-Drive for their work of art and Vari-Prop. Truly masterful machining and manufacturing.
I love that he stamped "Tally-Ho" on it.
Patrick, you knew something had to be asked; "do you charge extra for 'lumpy', textured paint work"? I'd hold out for a least an extra brewsky, at quitting time!😆
Work like this makes it feel much closer to the end... which I dread on one level. This has been pure joy for years. Of course, when I reflect on it I know there is still much to be done. I LOVE the fact that folks are contributing in so many ways to this effort. I know you've NEVER been about product placement or sponsorship Leo, but I'm so happy that companies are giving things to this effort simply to have their contribution acknowledged. This project seems much larger than just one man with a dream and his boat. Of course, you're that man Leo and we have deep respect for you and appreciation of what you share with all of us. Thank you. And folks, if you haven't become a Patreon member, I encourage you to do so. This is some of the best content on the internet... it is certainly worth supporting even a modest amount.
Did you see the video I think it was a few weeks ago, long story short: there is still a huge amount to do and lots of videos to come - it definitely feels as though it's getting close but really there's still a lot to go (:
that was exactly my sense as well! That we are getting close to the end here... I'd guess no more than 2 years away! :)
They're not nearly finished mate we many more hours of video to see
When it is finished , there will be voyaging and sail videos.
@@number1genoa - I hope he will charter some cruises... that I would fund very well in Patreon! hint, hint Leo...
Leo, you did an incredible job filming all that machine work. That was very fun to watch
if you like well filmed machine work, check out another of my favorite channels, Abomb79. kzhead.info
Agreed! I loved seeing the machine work in close up and slow motion
you poor, lonely, person
I had to stop for a second to say; Leo, despite your reservations, you explain things very well. Remember the K.I.S.S. system, you're doing great.
Finally worked out how the Variprop works in regeneration mode. Forward rotation of the prop shaft causes the prop blades to rotate into the forward thrust position. Stopping rotation and the blades will automatically move to the feathered or neutral angle of attack position. However if the prop shaft is rotated in the reverse (astern) direction the prop blades rotate into the reverse thrust position and remain locked there. If the engine is now de-coupled from the electric drive system and the vessel in underway by sail the prop will drive the generators producing power. To return to either feathered or forward thrust you need to move the gearbox from reverse through neutral to forward and apply power for a few seconds. The prop transition can be achieved with either the diesel engine or the electric propulsion system. This is genius as it means should you have a engine failure or just run out of diesel you can, so long as you can raise the sails, recover the batteries which can store 40 kWh of power. This is an insane amount of electrical power for a boat. Whilst it won't give you much in the way of range it would power most boat systems for weeks if not months. Possibly more important it gives you a back up emergency manoeuvring option. For example getting into a safe harbour with adverse winds. I was a bit stunned to work out that the eight Victron Lithium Ion 24V 200ah batteries cost £32,000 ( $37,438) but considering the hull value of Tally Ho it's a drop in the ocean, so to speak....
It fooled me till I saw your explanation, thanks Anthony :)
Thanks, I was scratching my head about that propeller!
Leo, you boatbuilder and a sailor… you’re also a very competent filmmaker and storyteller. One of the very best channels on KZhead or anywhere else come to think about it. 🇨🇦
.....And a sketch artist extraordinare.
Yes indeed he is one of the best.. and that's also the reason the boat will be finished and supported.
Leo is a singer and musician.
And has the amazing hairdo of a troll doll. lol

Beautiful work mate, take my money
Entire drive line is impressive but that prop is a work of art!
New prop technology . This Genius Propeller Will Change Transport Forever kzhead.info/sun/gKuyaM6unV96jWg/bejne.html
Bold choice showing the machining on youtube, basically inviting the youtube machinist concern trolls to come out and critique every last decision of the machinist. OMG, he was holding the file wrong!
In a world full of CNC and there operators, A competent machinist is very valuable.
We referred to ourselves as dinosaur's! Very few left nowadays, nice to see one work!
2 am here in Australia,,,,, not going to bed 'till I watch this... 😁 .... G'Day everybody 🤪
19:55 - I’ve been using the Custom BrushMaster 3000 for years & cannot tell you how much time & money it has saved me. the bristles were specially designed by top Nasa Scientists for the Saturn Rocket return systems program & the handle was specifically designed by the world’s most important ergonomic research lab technicians to date. obviously, I love using my Custom BrushMaster 3000, but don’t just take my word for it…here’s a few testimonials from professionals in the field that use the Custom BrushMaster 3000 in their daily professions…
I hear they make extensive use of the Custom BrushMaster 3000 at the Large Hadron Collider.
@@Xondar11223344 - I sure hope they use only High-Quality tools like the Custom BrushMaster 3000 at the Large Hadron Collider facility. an accident at that joint has potential to transform Earth’s matter irreparably & cause quite a stir.
You know I've had a Custom BrushMaster 3000 on order for 3 months now., but the supply chain is still a little sluggish. Hope to get it before Christmas.
Ever since nVidia took over production of the Custom BrushMaster 3000 the supply chain has been compromised. I've heard from reliable sources that they hope to remedy the shortage by releasing the Custom BrushMaster 4000 series shortly.
@@DavidWieder216951 I blame all the crypto miners for that.
Wow crazy that this was started back in 2017. It really doesn't feel like I've been watching the progress for that long. I've enjoyed every minute of this build 👏🏼👏🏼👏🏼 kudos to Leo, his team, and donators
Yes and I am looking forward to the day when this boat takes part in the Fastnet race - 2025?
That machinist is one chill dude
Hi Leo, to stop some of the fake scammers in the comments, add the key words they are using often to your "Blocked Words" in your studio settings. This will hold it until you can approve or deny it. I really enjoy your video's, awesome job as usual!
Or... he could spend his time working on the boat, rather than policing his comment section. And simply allow his viewers to rely on common sense not to fall for spam scams. Just a thought.
@@randomuser778 that was necessary.
@@randomuser778 I kind of care the he cares about the online safety of his viewers.
@@randomuser778 I'm all for "natural selection" when it comes to scams, but spending 30 seconds to ban 3 words probably won't delay Tally Ho by much
@@randomuser778 They usually don't post anything in comments. They send messages to people posting here. I have had the message twice, on different channels.
That was one Amazing video!!! Leo, you're camera work, editing, music, story telling, skills are second to none. This video was a joy to watch. It explained so much that the average KZheadr would never venture to spend time explaining. And you kept the interest up, at least for me, throughout the whole video. I cant wait for you to start explaining rigging, sails, and sailing theory. I just have to say thanks for the "two years" of entertainment and education. And thanks to all the people are and have worked for you and volunteered time, materials, equipment, services, money, ect, etc.
I totally agree with Lucian. Leo's Genius, yes GENIUS, is what has made this project so exciting. I compare his video production alone, to the very best documentaries produced by people with presumably far more "education" and training in video making and storytelling. as Lucian wrote, Leo is unique in all he does. I always wait with the greatest anticipation every other Saturday for 1/2 an hour of class documentary and as for the subject matter, awesome! (I never use ""awesome" as an adjective because I say, "what will you say when something really warrants that word? and it is devalued by overuse" well, I really think his videos and the project, in general, is absolutely äwsome". The Tally Ho restoration project is the best thing on KZhead. He deserves all the recognition and more! GREAT work Leo.
At 1:32 Leo's hair reached level 9.987 on the unofficial scale of such things. I'm 65 and have never seen anything over 8.99 including Little Richard. 😂
My day just got infinitely better, Leo, knowing that there’s a Sampson Boat Co video to watch 👍
It's incredible to see so many companies and individuals contributing to your project, Tally Ho is going to last another hundred years with all the quality parts going in with your beautiful hand work.
6:04 " oh, and he put 'Tally Ho' in it ! Isn't that nice ! " B-) Leo has really turned this re-build into a dance of high quality to the extreme . . . very nice to see so many greats participate with it.
I love how he still unboxes driveline components on his table saw. He is human like all the rest of us
My table saw is mostly table..
@@snaplash I do glue ups on mine. It’s the flattest surface I have. 🙂
Probably the only clean, level spot on the shop.
I know nothing about propellers, but I can tell that is a beauty.
Wow,from all the shaft seals and thrust bearings I’ve seen in my life, this one is really slick! I’ll bet she’ll be vibration free! I have to add that you must continue filming your sea trials and trip back to the UK. Don’t think I could not know how it handles after watching your series for so long! My condolences for the loss of your Queen!
@Barrie Harmsworth I like this CV joint set up. My prop guy told me the max amount the flanges can be out is .002" which is my thinnest feeler gauge. I've also learned that you have to align a shaft coupling in the water. The point loads while on the hard can distort the hull shape enough to cause a misalignment and the resulting vibration. While I've had a couple of pretty competent yards tell me otherwise, I've found it to be empirically true in most of the boats I've dealt with the issue on.
@@nesdonbooth9726 CV joints are a proper headache to design and get aligned. Even something more simple like a car's steering column, which is much longer, thinner, lower load and can tolerate much sharper angles, can be easy to mess up. Feels like no matter how many times I do them ,on any kind of shaft be it steering, prop, driveshafts etc. and no matter how much planning I put in and end up having to make at least 2-3 attempts
Wow. That metalwork footage is mesmerizing. So cool, not just Leo’s hair, that Tally Ho can finally float again. Great work everyone!
Another of my favorite channels. kzhead.info Booth does all things metal, including aluminum welding, cast iron brazing, spray welding, etc. Also marine work, from their Florida base. Well filmed also. It is, indeed, mesmerizing. Also including the details of chucking up, clamping, indicating for concentricity, etc.
Leo’s hair can float? That’s amazing.
Thrust bracket is a 'work of art', well done Dean in Seattle!
On behalf of myself and the thousands who turned out yesterday for the Open House in Port Townsend, I'd like to say THANK YOU LEO . It was a real thrill to see Tally Ho, you, your crew, and Pancho in person. Perhaps next year we will see her floating in the harbor...
Thanks Aquadrive!
This one was incredibly satisfying to watch. How cool to see all that planning, from carving the stern, drilling the prop shaft hole, planning the thrust bearing bracket, machining the shaft, to watching nuts and bolts be tightened. Amazing! Great work Leo!
i agree 💯
Hi Leo, great work! I have the same stuffing box and the previous owner of my boat machined a small threaded hole to the flax stuffing area and fit a small grease fitting connected to a copper tube which terminates in a small threaded grease cup. When back in my berth I give the grease cup a turn or two and it injects a little grease in the flax area which stops the drip while in port but heats up and allows water to still drip while underway, simple and functional. All the best!
sounds like a good idea.
I run the same but one modification, l have a grease gun permanently hooked up and a quick pump or two. Don't over grease tho can gum up a smaller bilge pump with the stuff that ozzies out or clogg up a narrow hose.
Seems to be standard on narrow boats.
You might end up slightly polluting the ocean.
Something so sweet about that propeller. I would give up my "in office 9 to 5" in a heartbeat for "machine work," as Dylan Maki described it!
Tally Ho can now float, ⛵⛵⛵⛵⛵⛵⛵⛵⛵⛵⛵⛵ wahoo. Nice job, Leo and crew.
Wow, that prop is a masterpiece (like everything else on Tally Ho).
Isn't it just though? Virtually everything on TallyHo, from the polished bronze floors and knees, to the paint job on the coupler in this video, that no one will ever see, to the flexible coupling that's yet faced off to a tenth of a thousandth of an inch, has been done the best it can possibly be done. I dare say this will be the best built sailing craft afloat when it's done. Tally Ho really needed some love sitting there on the Oregon coast, and Boy Howdy, did it ever get it! Every piece on her has been a labor of love.
SPW is not far from my home. I have such a prop on my yacht as well. German Engineering. 😉
Great to see a young guy doing intricate machine work. All of the machinists I know are old guys missing at least one finger!! (LOL)
This is a fantastic milestone ! At last the refurbished Tally Ho is watertight and will float. Congratulation to the entire team, to every last person who has worked on Tally Ho over the last five years.
😁I an sure you meant the last 2 years, right?😊
When I tell my wife I am going off the grid because a new Tally Ho video drops. She always asks , " what does his hair look like today?" (Go figure). She stated "Leo's hair looks particularly spectacular today!" Not sure if it's on purpose or in jest but well done today Leo. Paint job on the coupler was mighty fine and will do the trick. Those bronze and stainless steel parts are quite nice. Thanks for taking all of us along on this journey. I look forward to seeing Tally Ho on her seafaring journey as well. I can imaging her rounding Cape Horn and sailing in the Roaring Forties and Furious Fifties. Leo at the helm with a priceless smile on his face.
I had to call my wife into the room and show her Leo's hair at 1:50, 21:00 and 24:00. Ahh, those were the days, having enough hair to feel like you got your money's worth on a haircut.
Just imagine his hair in those latitudes!
I've actually started wearing my hair the same way...
Been watching since you bought the original. That waz along time ago. At the age of 89 this year, I hope I live long enough to see if it does float. Wish you well. Gramps
Your filming style is truly artistic. From the shots of the boatyard to the close ups of the laithe and the mill, it’s all so pleasant to watch.
Huge props to whomever shot the slow-mo machining scenes! 💙
If it was Leo, he literally got a huge prop at the end of the video.
I have a somewhat smaller Variprop on my 35 ft cutter. It works very well until it fouls up with marine growth. I have used many prop antifouling systems and strongly recommend you do the same. The best one so far has been a silicon rubber coating which results in growth spinning off whenever the prop is engaged. It also lasts longer than the more conventional prop antifouling but is more expensive. Edited to correct spelling.
How do you control and change the pitch of the prop? Is it done remotely?🙏
@@fishbowl925 I wondered the same thing, but I have a suspicion that as the water flows over the prop it will change by itself due to waterflow. I certainly didn't see any control cable. As to blades of the prop move in a certain direction, I am going to assume that the prop will move against that flow, producing no thrust, until as such time as it hits the stops, and then it will stop the angle change and then start producing thrust. I doubt that would take more than half to three quarters of a rotation of the prop. As to the sailing position, which is zero angle to the waterflow, I suspect that is probably the default location and may have an internal spring set up. You can see a demonstration on SPW's KZhead page here: kzhead.info/sun/pMaQp5ptnqSOl2g/bejne.html
I was wondering the same thing. I think there must be mechanical stops inside and the rotation of the shaft shifts the blades until they hit those stops at the right pitch.
@@fishbowl925 I wonder also. I watched a video about a Nordhavn 56 MS Hundested controllable pitch prop. It had a rod inside the prop shaft to control the angle.
Thanks for that, the video was great, a very clever bit of kit! 👍
Your hair is looking particularly lively today! Always a joy watching the project progress.
Looks like you are going for a Yugio look! Lets get ready to b-b-b-b-b-build!😀
I'm one of BILLIONS who love Leo's hair style, right!!!??? Fantastic....Leo!
Cutlas bearing rubber can if left dry too long before being wet can stick to the shaft. When the shaft first turns it can pull the rubber off the tube. Simple fix is to check with careful rotation before putting engine power on. Alternatively, if that is not an option, put some ordinary washing up liquid and water mix on the shaft and rubber. Make sure to add a little water otherwise the washing up liquid goes sticky. That stops the sticking, and it washes off as soon as the boat is in the water. Done it a lot with industrial units that can sit a while.
I saw Swarfega used on cutlass bearings when I worked in a boatyard many years ago.
@@andychurches7280 I' don't remember if Swarfega has abrasive particles in it. But if not, then yes as it is a water soluble wetting agent it would work too.
@@andyrbush yeah, I'm pretty sure the original green swarfega didn't contain any abrasives. The modern orange version possibly does.
I enjoyed that video , as in another life I building Nuclear submarines I did a lot of work doing exactly what you just did. the prop was 19 tons. for perspective. As a boat builder and sailer I have enjoy every moment of your journey. Thank you
Groton or Newport News?
Feels like a major milestone ticked off.
It was an absolute pleasure to see that mechanic doing his job so precisly and skilled. Metal work at its best.....fits perfectly to your wood work ;-)
I've said it before, but this whole boat is pure art. The craftsmanship that has gone into every piece just shows it again and again
Odds are good I will never have another boat, let alone a magnificent cutter. But by golly! Your videos do feed dreams, and just pur love of boats!
Just saw the boat in person today; hopefully Leo’s ego survives the well-deserved vigorous massaging everyone was providing lol Thank you for inspiring so many of us!
This boat is an Icon that could have died in a boat yard rotting away to nothing. Leo the Iconic boat builder had plans to restore the beautiful boat back to Glory. He didn't have much in his pocket but he created a community and pulled in support from around the Globe. What was a vision is coming to life which makes me so happy for him and the people that have been evolved in this journey. Anyone thinking life is too hard should watch this boat build from Start to today, truly inspirational and educational content.
One thing I like about this model for building something is that people just help. The project itself is incentive enough to participate. No profit incentive necessary.
Hi Leo and gang really have enjoyed this program since the beginning. Oh forgive me, very saddened at the loss of your Queen my sincere condolences. Thank you for this very enjoyable series.
That Bridgeport is super nice. Super old. It was a Cadillac of its kind when it came out. Super cool
Well, it isn't a Moore Jig Bore (also from Bridgeport, CT) but it certainly was the benchmark of knee mills for for over 60 years
This is the only time I have ever NOT pressed "Skip Ad". Glad Leo is making a little more.
I am reflecting how such small items like bolts and screws actually “secure” the part. They seem so small against the task they perform. Ironically they & their function give me hope in that what often seem like Herculean tasks in life that we overcome are done so by many incremental small small tasks. Is it my logic-lessness or is it logical to think that such a small propeller can actually propel such a large boat forward or backward? When we stop to think about it, it’s an amazing world in which we live. We, well I just need to stop more often and appreciate more. So taking a stop moment to acknowledge Leo, his skill sets, enthusiasm, humor, music choices, energy and of course the sharing of the Talllyho re build project.
Holy smokes, that dial indicator is rock solid 18:54 - great work!
Very pleased to see the old Bridgeport mill and lathe. I trained as a machinist back in the early 60s and finished my apprenticeship in 1967 on many of these types of machines. The CNC and computer operated machines of today are way past my understanding. This was a great look at machining of almost 60 years ago. Thank you.
Worked in a forklift factory years ago that had robot welders and CNC - everything; state of the art and all bells/whistles. I worked with an old fella who ran his own quiet area away from all the drama, with 3 bandsaws from antiquity and a heap of raw materials that we scavenged for cutting up to make all manner of little blocks to order for the robots to weld or chew on. The whole space-age operation would have ground to a halt if it wasn't for the old fella in spectacles with his tape-measure.
@@dancarter482 I know exactly where you are coming from.
I trained to use a CNC, but first they made us use old lathes and mills for weeks and I gotta say those are some sturdy, and amazingly engineered machines... The precision and finishes you can get using them is just incredible
@@racsofischer7601 I have a nephew in Minnesota who has his own shop. He is self taught on the CNC and several automatic machines he bought from Switzerland. They are absolutely marvelous, but he like you learned on the older machines. He still uses his Bridgeport mill and I think he has a standard lathe to do one off parts. I was amazed at what he was able to do with his automatic machines.
@@formerparatrooper I'm from Switzerland too
as a 28 year machinist well done Dylan. Solid work
LEO ! We got a SCREW !! & we water tight !! and I really appreciate it ❤❤👍👍
As always-VERY professional video and installation of quality parts. I believe George is giving Mr. T a run for his money with all the jewelry!
I pity the fool!
"it can now float" is such a huge step, like, it's a boat now, it can at least get towed and if you wanted could have a rally tank added and actually move through the water on its own, that's amazing!
As a hot rodder the machine work is first class.
I couldn't help but smile when he said "for the first time, the boat is watertight and able to float." Only two more years!
I don’t think that Leo could ever sell this boat… it’s not a build it’s a life story.. If it was mine I’d spend hours at the fireside remembering all the people who were involved in its creation.. I watched the very first episode with my baby daughter in my arms and now she’s 5 years old.. One day we will go and see Tally Ho . Thanks for the update Leo 🙏
I was thinking of the first episode, I didn't realize it had been that long.
A big milestone in the whole project, I will not deny that it did get me a bit emotional seeing that prop on tally ho’s tail, huge congratulations to everyone involved with the re-build 🎉🎉🎉🎉, there should be a preliminary celebration on each one of these milestones. Well done Leo and the gang. Having followed the journey from early days this is one to remember for sure. Bravo 👏 👏👏👏👏
Yes, should be “Whiskey Plank” and maybe “Gin Prop”. Hmmm sounds a little bitter though…..
It’s pretty awesome, Watching you come from a wide eyed kid with a dream. To a WORLD class ship building MAN. Good on ya
It was good to see you at the open house today.
I've always appreciated the quality in old school engineering, and old school craftsmanship in something like a 100 year old wooden boat. This video series has been a treat in that respect. As you got into the hybrid motor, and now the details of the AquaDrive and all the ancillary pieces, we get to see that awesome old school work blended with top end modern engineering. A veritable feast!
WoW that screw must have cost a penny or two, I know how much I payed for my trawler screw to be refurbished rather than forking out for a new one. Fair wind and a following sea Leo ✌️🇬🇧
It's so awesome that companies donate what looks like very expensive equipment for Tally Ho. The mounting plate is beautiful! Throw some flat washers on the bolts though. It adds an incredible amount of clamping power more than just the bolt heads alone. Get some big fat fender washers even better.
I had never seen any of your videos prior to this one. My son asked me to drive to Port Townsend today (Sept 10, 2022) for the Wooden Boat Festival. As a result we toured the Tally Ho and got to meet you. I now get the fortunate pleasure of being able to go back and watch all the previous videos. Thank you for sharing your project.
Good on you. As a onetime avid sailor, and still an avid woodworker and sometimes machinist (musical instruments), you give me a lot of vicarious pleasure for the boats I will never build or restore. It's always heartening to hear of energy, ingenuity, craft, and love still at work in our tired and cynical world, to bring something of beauty to life again. cheers from overcast Vienna, Scott
Tally Ho is a beautiful piece of functional art; the woodwork, bronzework, fabrication, casting, machining etc.; boatbuilding meets art, engineering and science. You've taken and restored an old racing yacht and repurposed it for a 21st century cruising/racing yacht, at the same time, making the process a teaching and educational element. When you've completed restoration and sailed Tally Ho back to the UK, you should put Tally Ho on temporary display in the Tate Modern, a repurposed power plant to contemporary art museum. Tally Ho and the process would make a fantastic temporary art installation. Best of luck!
I often use the term "Functional Art" and couldn't agree more with you!
Another gr😮eat video… its just soo far away from Aussie living.. great that you take us with you to areas at my age I know I wont get to see.. your vision captures and overall content is always good quality… thanks soo much
AquaDrive components were specified by a well experienced customer in a boat I designed. They proved to be really good, and made this craft extremely smooth and quiet. The diesel engine ended up sounding more like a quiet electric motor, and vibration.... NONE ! The thrust loads are not so huge as Leo makes out. People often go OTT with their load guesses. Use the real numbers, and you can engineer things without adding excessive weight.
I'm a marine engineer and am accustomed to working with controllable pitch propellers. Those are complex systems. I was interested in how these feathering props work and looked up the company. The website was informative and answered my questions. Very cool! Btw, variprop has a KZhead channel!
How do they change pitch ,I asked before in comments, but got no answers

This part of the project could not have been done so professionally without Patrick's assistance. I think he had the Greatest Responsibility and Pressure to make it all come together.
Patrick is my absolute favorite! Just wanted to let the world know.
Beautiful piece of jewelry for the boat.
Looking GREAT. As a machinist, an episode I can fully appreciate with complete understanding. Nice machine work that was done properly without any short cuts or "hacking". Nice work.
Were you wondering why he was using a parting tool for facing?
@@cyrilhudak4568 No, they cut straight and can handle a heavier cut.
That thrust bearing mount is beautiful.
What beautiful engineering is that Driveline thrust bearing and it’s components.
used to be a machinist in my younger years, great to see Dylan working on the shaft and coupling...took me right back. Great quality of work again and I wish more machinists would fit jacking screws to their keyways!
I do love me some old school machining and machine tools! Bridgeport mill FTW! I very much enjoyed the open house this morning! As I told Leo, this project and channel have made my life just a little bit better.
I switched from the traditional packing in my packing gland, to teflon rope. I never had to change the packing after that and it was easier to control the 'drip rate'...
Has it been in use long enough to score your shaft yet? Teflon is famous for that.
@@two-sense Not really, 2000 rpm combined with infrequent use and constant sea water lube meant no galling over the life of the shaft.
@@mikeskelly2356 Got it. So if you use Teflon, as long as it's only subject to "infrequent use" everything will be fine. Thanks.
Amazing amount of fine tuning to complete the driveline installation . The top quality engineers who Theo has sourced / discovered are all priceless. that assembled driveline looks amazing .
LEO sorry my Swiss friend is Theo. 78 year olds get mixed up .
I've worked on stuffing boxes before quite a bit, but for water pumping windmills. The usual material for such a stuffing box is graphite impregnated material (rope). Works, but you CAN get square teflon material in a "rope" form. You can buy it in a square cross section in several sizes. So if you need to fill up the stuffing box, you get the appropriate size, cut the stuff to form "rings" around the shaft. just offset the breaks in the material and by doing that, it won't leak. Teflon is the best material for stuffing boxes in my experience. Better lubricity than anything else, LIKES oil or grease, and last longer than any other material. And like the graphite rope, you can repair it or replace it. Just a thought.
I just didn’t want this video to end… not only because of content,but also because you’ve become such a great videographer. I don’t think you’ll have any problem selling your work in the future. I for one would watch anything you put a hand to.
Since 2017, wow I just realized iv been watchin you build this boat almost 6years 😲..and it's been worth every minute of it.. I'm from Arklow in Ireland where u said the boat was once owned if I remembered that correctly, it may have been made here too was it? Tyrells Shipping was a pretty big boat yard here and still if. I really hope you take us on the journey across the Atlantic when you are taking her home.. that would be so awesome to see also. Thank you Leo for bringing us all so much enjoyment watching this build over the years. Props to you, your a very skilled carpenter, puts my skills to shame 🙈

I have one more addition?! As Glan seal. there is almost certainly a Fiber-like Use. Then lubricate the gloss on the water side with a naturally safe grease. However, THERE is also a rib pack. Made of Pure Graphite (used from space to protect (melting upon return to the atmosphere) that material is for sale, as a ribbed band. If you press it into a model, you create a split (oblique) seal or not. It doesn't need any lubrication. is completely 100% natural and has a lower resistance than lubricated with grease. the wear of the axle. (stainless steel) is also nil. Even with a heavily sanded water side (sand for example), the stainless steel shaft becomes highly shiny. I used that combination for a pump. which had to process both vacuum and high pressure.

Excellent choice of an SPW propeller I fitted the smaller model Variprofile from SPW to my yacht 12 years ago, and have had zero issues since . Just give it an annual shot of the special grease & you’re good to go.
Beautiful boat, work, organisation, details, crew, camera, editing... whole thing!
17:45 As a young man I operated a Bridgeport mill. I cut many a keyway on the Bridgport, shaper and press. Half inch keyway using a tool steel broach on a press. I can smell the oder of the cutting oil.
Holy Crow Leo, you look more and more like Sonic the Hedgehog every video...love it!
Beautiful work and amazing donations of what looks like “boat jewelry” for the drive train. Very high quality parts from outstanding companies. 👏
That is one beautiful driveline. And that prop. Very nice. Cheers.
just got home from Port Townsend to see the Tally Ho. No way were we going to wait in line...lol...We got to see Leo, Pete, Patrick, and all the new guys too. We were lucky enough to chat with Patrick's folks for a bit and pet their Golden Retriever. Nice people by the way...We brought our dog too, but he stayed in the van (vent fan turned on, Reflectix in the windows, windows open, water, and food.)...the boat show didn't allow dogs so of course we obey...so then we go in and see numerous dogs walking with their masters. We walked the docks in the marina, then drove through town, and got out of dodge...Next year we'll plan on staying longer...looks like a good time...Thanks Leo, and Crew for the open house.
