From old broken parts to custom patterns ,castings machining modifications and upgrades this project is really a combination of life learnt engineering skill, passion and solid dedication much respect Keith your doing a great job 🙂🇦🇺
It seems Leo and the crew are almost ready to install this formerly rusted tight and broken piece. Great work Keith, it should be good for another 100 years of service. Certainly, it's been a long-distance, multiple-input project, but it's coming to it's completion... Thanks, Keith, it looks great...
One would think if it goes another hundred years, then those dog hold-off levers will have ends break off again, since the (failed) design was not modified... not thicker or wider..
Or were they a different material? I didn't catch that.
But I suppose the dogs really won't ever be used, since they added electric drive. Heck after the first or second time they try to run the capstan motor with one or both pawl dogs in wrong position, they might just wire or epoxy them out of the way.
Or use a pair of slip joint pliers tio unscrew and remove the dogs
@@ssn608They lasted for a hundred years and yes. they will be used again. The capstan is now designed to be used manually and with a motor.
It probably already is installed. Leo asked weeks ago if anyone traveling from southern GA or FL to the PNW could pick it up. These videos are often not up-to-date and could show things from a month or more ago.
@@snappingbear They didn't actually last for a hundred years... they were broken before the restoration processs began.... probably MANY years before Tally Ho was last put on the dry.
And yes, I have followed the project and listened to this video, where he explicitlty says that the dogs would be lifted during electric operation. So presumably, the levers wouldn't see as much abuse as they did over the previous 100 years.
However, having some knowledge of Human Factors Engineering.... when you have not one, but TWO pawls on opposite sides of a capstan, where they both may not be in easy view of the person operating the capstan, and multiple people (at different times)) operating the electric drive, no interlock preventing operation of the the electric motor without ensuring the pawls/dogs are in the proper position (I haven't heard about provision of an interlock, have you?)... how many days (weeks... maybe) do you think it will be before someone operates the capstan in a direction that is blocked by a pawl? And what will be the result... what will give (break) on the capstan; because if the capstan motor has enough torque to be useful to help warp in a boat of Tally Ho's considerable mass and wetted area to a dock or mooring buoy, and that motor is started with one or both pawls engaged to prevent rotation in the direction the motor is trying to rotate the capstan, I believe SOMETHING will break (hopefully a shear pin coupling the motor to the gearing). And after a couple of inconvenient and perhaps expensive repairs.... will the pawls and the locking lever still be installed and operable? I'm not sanguine about the length of time that the locking levers will remain operable.... they may be removed from the capstan along with the ratcheting pawls/dogs to prevent such problems in the future. And if they aren't installed, they aren't operable.
@@ssn608 If they have the motor fed through a motor starter hopefully it would trip before any damage in done. MS are designed to trip when the motor draws more current than normal.
The Tally Ho is floating, and the main sail is up. Hurry, hurry, hurry. Faster. (To be clear for the tiny-brained folk: I am totally joking. Kieth is one of my favorite TH-camrs, a wonderful worker, doing an astonishing great job of repairing this capstan. I am mightily impressed with Kieth's diligence, hard work, and meticulous execution.)
It is so interesting to see how much knowledge and craftmanship went into the capstan 115 years ago, and how much knowledge and craftmanship it takes today to recreate it and adapt it to 115 years of progress.
I think Keith did an excellent job balancing real world with project deadline. This isn't a perfect winch meant to sit in a box and never to be used, this is a winch that's going to carry chain on Tally Ho's pristine deck and dent the schnitzel out of it. CNC gangs begone!
I've really enjoyed watching this capstan restoration - a much bigger job than I'd imagined.
I correctly imagined that it was a big job. BUT... the right people are working on it.
yes, it's been quite a journey to follow this project from pattern maker, to the foundry, and to the machinist.
Keith,
My father was a machinist and a tool and die maker. I’m 82 so that tells you how long ago that was. I spent a lot of time with him during school vacations and holidays. I love watching you work and can almost smell the fragrance of the cutting oil.
Thank you for sharing your skill and ingenuity with us.
Kieth I’m a finish carpenter by trade and don’t know much about machining parts, but after seeing your work I have a new appreciation for what you do. You have mastered your trade! Great job!!
Most don't knows that Keith is also a highly skilled woodworker who makes furniture. You're only seeing half his shop, the other half is full of woodworking tools and machines.
Did you also grow up in Finland??
:^)
From one machinist fabricator to another: I think Tally Ho may need a couple extra of those bronze levers! The originals were most likely broken because they got caught in the anchor chain, which seems inevitable. You also may want to consider slotting or putting some flats on the shoulder bolt heads for easy lever replacement.
I was biting my nails when he was tightening the brass bolt with the channel locks. 😆 🤣
Not brass. Aluminum Bronze. Its MUCH harder stuff.
@@Fullion-CA Still a poor choice.
Still mared up just the same...... 😠
some flats machined on it would have been nice.
LOL, same here. I could not believe it.
Appreciate all the editing that goes in to your videos Keith - no dead time, only 30 minutes long .. I was introduced to the Tally Ho project from your channel first, and now am following Leo as well
I was watch both of these guys separately, not know that they'd ever work together.
Shows how good engineering was over 100 years ago, It has taken some of the best in the USA and the UK to repair this capstan. Truly amazing engineers back then and around now, I can only applaud you all,
It’s interesting to note how many beautiful machines from that era are still out performing modern, made to a price, machines. Down side was I suspect the machinists of old were paid a pittance!
@@johnsherborne3245 Yes, Using old machines that work like new,
My first machining task in the local Naval Dockyard was an aluminum bronze dovetail mount for a precision optics component used to calibrate a fire control director. Not being a trained machinist my boss insisted I leave a tiny witness mark from the original cast surface so I could not be accused of taking off too much material from the expensive one off slab. If the customer supplied cast material was a one off we called it variously Unobtanium, Drillium or Wishalloy . If someone stuffed up a job we would laugh say he has used Eludium :-)
Again, what an interesting project. It really shows a lot of people the amount of work and setup a general manual machinist has to go through for what sometimes looks like a simple job.
I always get a kick watching massive machines like that horizontal boring mill, or the Carlton radial drill used to make little holes.
I thought he was going to use that boring mill for the Stoker Engine.
Bit surprised you spent time turning a nice finish on the pin then mangled it up with pipe grips! I would have put a couple of flats for a spanner on it.
I was thinking the same thing too. Especially considering it's going to be so visible.
Agreed
That's another hour of hand sanding and polishing the pin once installed...
I agree, seems a bit off from the rest of the standard that has been established. That and applying the lock tight on the parts prior to final assembly (after paint)
I thought that too, and to be honest I was also surprised that the fittings were Loctited on before the paint finish was applied. That's going to leave some un-painted surfaces which may not be visible to the eye, but will be exposed to the elements.
Totally agree, there are many options to cleanly tighten those bolts long before you reach for the pipe pliers. All that lovely machinery and the plumbers pliers were first choice.
Keith I CAN NOT WAIT to see The Capstan in its Proper Place on The Tally Ho !! Leo and his Studious Crew have worked Their Hinnies off Rebuilding The Tally Ho to its Former Glory , and now that its Afloat and nearly ready to Sail Again , The Capstan will Again be Mounted where it was for more than A Century !!!! Great Work Keith !!!!!!!!!
The heads on the bolts holding the dogs MUST BE “safed”, meaning round heads and nothing sharp so the ropescannot get hooked as they spin on and off the capstan. The first hand drawing was correct.Also think of sailors toes as they work around the capstan. Wonderful work!
When I did my training in the UK, the taps were called, 'Taper', 'Intermediate' and 'Plug'.
Or 'taper', 'second' and 'plug'. Not that it matters!
Same :)
Thank you Keith for sharing this project. Very satisfying to watch.
It’s always lovely to see top quality work being achieved.. 👏👏
Tally Ho is floating now and the sails are going up! Looks like the capstan will be ready just in the nick of time!
Great work. Will see it when Tally Ho makes it to Australia.
Fantastic job, can't wait for the capstan to be installed on TALLY HO. Well done
Keith.
Not to many old timers left that can do that kind of precise manual machining. CNC is great and all, hit the GO button, come back an hour later and your square billet is now something. That being said there are still applications where CNC can't do the job and it takes a professional machinist with experience to pull it off. I enjoy watching you make the complicated look easy.
Please, when using the pliers use the end of the prongs, the beak so to speak.
It will prevent slippage and thus leave no marks when tightening a bolt.
Have been watching Tally-Ho from the beginning and this channel for a long time. This project looks great and should serve Tally Ho for another century. Great job.
Us woodworkers now know what a tap follower is. thanks for your patient explanations and great progress.
Thanks for sharing.
Fascinating as ever. Thanks for sharing.
Excellent work. Finish line within sight!
Thanks Keith.
Great to see those wonderful big old machine tools.
The only concern I have with the dogs to stop the rotation is the capstan was originally made for manual operation. Now that it is going to be converted to a motor drive and if someone operating the capstan motor forgets to switch directions of the dogs and starts the rotation and it comes up against the dogs that stop that rotation that the power of the new motor may cause to much stress an will break the gear housing or break off the dogs and ruin the casting by the pin holding the dog will break off or break the cast it goes through.
I suspect that there will be a similar system that works the same way windows in cars stop when coming up against resistance.
@@Rog_Ramjet I hope so, perhaps a circuit breaker if the current is excessive or a mechanical clutch or shear pin in the drive.
It’s getting exciting as you near the end, well done..👍
How cool would it be to see a youngster here being properly apprenticed to this master craftsman.
Keith, I am going to admonish you for not covering that boo-boo on the back of thumb. The reason I'm doing it is because after my left knee replacement, at the VA, when the doc removed the staples there was blister around one prong of a staple. The doc didn't dress that open wound and as my luck would have it I got an infection in the knee, which required them to reopen the knee, replace the plastic knee cap liner. I think I went through a lot of unnecessary pain and reaction to some of the antibiotics they put me on. Please if you have an open wound, no matter how small, properly dress it to preclude an infection.
I started my journey watching machinists' video, from there I moved to casting, including big lead quills, and to wooden boats construction and I am back to machinists...
Your painstaking work on this project is impressive, Keith. I, for one, don't object to the time you've invested on the capstan - everything else on Tally-Ho shows the same commitment to quality and fine craftsmanship; Take your time, and keep up the good work,
Thanks Keith. I appreciate you sharing the work you do!
Brilliant craftsmanship - great job!
Good morning Keith! It is turning out great. Thanks for the videos.
Fantastic effort and result Keith!! As all of us here I can’t wait to see it installed and working on Tally Ho! One more amazing contribution to the stunning Tally Ho project
A lot of work (LOL) bit of an understatement! Super Massive I'd say!!
My father was a machinist and a tool and die maker. I’m 71 so that tells you how long ago that was.
Thank you Keith 👍
i have found this to be so interesting. i plan on going back to see if i can watch other projects as well. can't believe how cool this is.
I had no idea how much skill was involved in your trade .
It is coming together. Workmanship and knowledge is beyond great.
Thank you for sharing.👍
you are a wonderful machinist that is a joy to watch
Great job! Your encouragement reminds me of my last 7 mile hike. We are further than we once were and then we were done.
Hope you will have a nice sailing on Tally Ho! You really deserve it! Bravissimo!👏👏👏👏👏
Man, I enjoy these videos so much. I probably wouldn’t have watched them if it hadn’t been part of Tally Ho, but I think I’ll continue to watch your videos no matter what you’re working on.
I can't believe you tightened up those lovely fasteners with pliers
I was cringing when the pliers were slipping, I guess it wouldn’t take much to machine them smooth again. I think I’d put a couple flats on it for the next guy,
I think he's going to peen-form those to rounded tops like his drawing.
Right ,and getting them back off will be even worse. A couple machined flats would be ideal.
Only 2 years left!
Nice work Keith.
Thanks for sharing the process.
I like seeing the HBM Machine being used. 👍
Have a great day.
once again beautiful
It is an absolute joy to watch a real craftsman work. I grew up next to a real blacksmith shop (that indicates my age) and he made amazing things without modern tools. You take it to a whole new level. It is fantastic.
Great work Keith!
Anticipating the top piece Drum you forged and seeing it fit will be a Great moment of relief for you and others who put so much into it .... seeing them together will show everybody how the Captand looks whole .... then the painting will make it look better then when it was new over 100 yrs. ago .... masters each everyone of you ..... Leo is going to be blown away .... it will be like a Christmas Present .... Leo will be grining ear to ear with a big smile .... ❤❤❤🎉🎉🎉😊😊😊 ..............
Ratchet pawls are very important. The larger capstans have bars inserted in holes around the top and if a pawl breaks or does not engage the drum will fly and the bars will do bad things like break your body. This type of capstan has a crank which can still hurt you if it goes backwards. These are amazing and simple machines. Sad it is not remaining original and a replica made but then there are still lots around to be reused and rebuilt.
Excellent work, presented in a most patient and professional manner, Keith! Thank you for all that you have done!
Looking forward to seeing the top of the capstan. Awesome work Keith! You guys should collaborate and write a children’s book about its 100+ years travels.😊🇨🇦
Capstan videos coming thick and fast
as well as the capstan itself, which is superbly done, you've created a legacy of knowledge of techniques and engineering.
Well done!
Great job on the cabstand. I love it and I love how you go through the process. Thank you.
*capstan
They rebuilt an entire boat in the time this capstan has taken.
Great Job Keith. I’m so glad you did it YOUR way!!!
Just astounding the amount of work. Thanks for taking the time to share with us Keith.
Leo is going to be so pleased with the entire teams efforts of this capstan. Keith, you have been a major player with your amazing work.
Honestly I would have been shocked if you were of by more than you were when you aligned the the first drilling, that being spot on, you are too much the machinist!!
Another great video on the Tally Ho Capstan project Keith! Watching you problem solve to figure out how to recreate the puzzle pieces of this project has been very enjoyable to watch. Thanks for sharing!
Thank you for your hard work and informative nature. Windy Hill Foundery and your channel have eased my Tally Ho video edition. So cool to see metal work in it's finest!
You make my day better when I see you at work. So pleasant to watch and learn.
Once again, great job 👏👏
Nice work. It’s going to be a perfect blend of vintage design, and modern functionality.
Its been fascinating to watch this rebuild and its going to be great to see it back on Tally Ho
Keith you do very fine workmanship on anything.....Thanks very much.....
Old F-4 II Shoe🇺🇸
This has been such an interesting project. Some parts looked so easy and others looked like a nightmare.
Crazy talent Keith! I hope the people making the chain are as talented as you are. 🤞🤞
Your awesome Keith. I think that Leo is watching this and loving every moment. I love working with brass and bronze. Kind of that great gold looking stuff eh, LOL. This is just plain great. Onward to the next post my friend.
Congratulations.... from Sweden ❤❤❤
Hope you finish soon. Tally Ho is in the water and almost ready to go. So let's go. Beautiful job by the way. Fantastic.
Excellent work! Always a pleasure to watch. I can't wait for update on the floor modifications for the lift.
Wonderful series Kieth. It’s been an eyeful learning what it takes to build the parts necessary to restore this historic piece. 🇨🇦
this has been an interesting rebuild to say the least and with a little luck this version of it will be around 100+ years from now with these videos showing its history
a truly nice project that asks for medium heavy machinery and a lot of thinkering
it is a final product that you can be proud of
I'm anxios to see the cast top and the finished project
excellent video.
A lot of detail work went into that capstan!
Leo's capstan is a work of art ! Nice job !
That's a solid and good looking piece of work. The arresting levers make me wonder if they are still needed in the case there's an electric drive, but that might require some worm drive transmission somewhere as a way to arrest the capstan. So in absence of a self arresting drive, you would still need them.
In the past the capstan would have been human-powered and I guess that will still be possible with the new lid on top. As a backup for failing to hoist the anchor electrically - flat battery, blacked-out e-motor - that would be a great thing, but a self-arresting e-motor-transmission then should have a clutch of sorts.
So, I'm trying to imagine where the capstan design is going, after vintage machinery ;)
The capstan motor design includes a two-part sliding driveshaft w/ a built-in dog-clutch. Releasing a deck-mounted lever lets the spring-loaded lower half of the shaft engage w/ its upper half - push the lever down to disengage it & the capstan is back in manual mode.
@@frederickstibbert7389 what prevents the dog-clutch from engaging when one of the two arresting levers are engaged? In a stress situation with 40' of winds and a moving deck underfoot, an engaged arresting lever will most likely be overlooked!
@@mygoggiesperfecture - Operator error is gonna be possible! You'll want to have the external pawls engaged (in the proper direction) when raising the anchor - I hope the motor will have an internal circuit breaker for overload protection.
There must be a lot of things missing in this conversion that are not shown. An anchor windlass with the gypsy integral to the capstan must have a brake and be capable of freewheeling. Anchors are not dropped one ratchet notch at a time with someone lying on deck to manually lift the ratchet pawls between notches. It would literally take hours to drop just a few feet. Since it is being converted to hydraulic drive, the drive motor must incorporate a brake. Since there is no provision shown for a clutch to allow the capstan and gypsy to operate separately, and there is no separate brake for the gypsy the anchor cannot be dropped without hydraulic power. Is the hydraulic system going to be fitted with a manual braking valve that allows modulating brake tension? In any event, those ratchet pawls are now irrelevant except for respect for original appearance and the risk of stalling the hydraulic motor and causing damage to the bronze gearing. The little bronze levers are just latches to hold the pawls off the stops for the original manual cranking system.
@@oldtugs - The new motor will be electric, not electro-hydraulic. It'll drive the worm of a worm&gear transmission, whose gear will turn the lower half of a new 2-part driveshaft that engages the new bronze gear inside the bottom of the drum. The 2-part driveshaft will incorporate a manually-engaged dog-clutch.
Thank you Keith!
I'm so excited to see it finished.
Great work Mr Rucker! I hope you get to see the capstan installed on Tally Ho
and the I came across this video. It gets better and better!
I really enjoy your channel and have found this project fascinating to follow along with.
Löve the progress on the capstan project! Lets TallyHo sail this summer!!
I am also very puzzled why Keith used those pliers, my heart stopped when i heard that "graunching" sound when he tightened the threaded stud to retain the ratchet dog leaving nasty scratch marks, what a shame to spoil that nicely turned finish. I understand that he is under a lot of pressure to get the capstan finished and shipped off to Leo but surely a few more minutes on the miller to put a screwdriver slot on the stud would be ok, or even wrap a few turns of masking tape around the stud to prevent damage.
I have admired Keith's fine workmanship all along but must admit it was a bit of a shock to see that moment.
Cheers from the UK.
well done
