Tally Ho Capstan Project: Part 4- Pattern Wrap Up
ฝัง
- เผยแพร่เมื่อ 24 ต.ค. 2023
- Dave starts a new project: make a pattern for a capstan for Sampson Boat Co's 1910 English sailboat named "Tally Ho". This is the Part 4: Pattern Wrap Up.
Capstan- a machine with a drum that rotates round a vertical spindle and is turned by a motor or lever, used for hauling in heavy ropes, etc.

Always appreciate Channels that push back on the "Your doing it wrong" crowd. Your the expert, people just need just shut up watch and learn and enjoy. Appreciate you and your efforts to keep old techniques alive, its for historical boat after all.
Fully agree. I grew up in the 90's tweening analog and digital, and it amazes me how much overlap there is in digital software that is rooted in the "hands on" getting dirty methods. If people would only stop to listen what is being imparted on them. Damn near every digital "tool" is named after its analog counterpart. Better yet they inform users on their intended uses. This man preserving those methods is so invaluable. Hell as a result of this channel, I now know the full implication of what "pattern grade" mahogany is and its uses.
I couldn’t have said it any better.
Just ignore them. You will never please everyone. Don’t try.
I get the impression that he isn't a professional teacher so the better approach would be to just show us what he is doing and let us work out why things were done.
Yeah but you're doing it wrong
Beautiful work and Craftsmanship!
I am delighted that I have found so many channels, in so many differing crafts, that were all related to my now years-long obsession with Tally Ho. I did not discover Leo and the channel from day one, but it has been a wonderful experience since I did. Now, all that said for WHY I found your channel, thank you for teaching these crafts, and I thoroughly enjoy your content as well!
I've been down a similar path. I started watching Keith Rucker a long time ago. Followed him to Clark Easterling. I don't remember how I found Leo,but his project led me back to Keith, and then to Dave and back to Clark. Lots of other people along the way.
Surprising how things go around.
Thanks to all of you!
Hi from England, my great grandfather was a pattern maker in the great wars, my father said he would watch him at work all day long, my father has recently passed, watching you at work somehow gives me comfort, I myself am a mechanic, but just love the way you teach and I find it so interesting, guess that’s a trait I’ve inherited, love the videos, been watching Leo from the beginning, that’s how I’ve stumbled on you 👍
Always a pleasure to watch a true craftsman. Thanks
Absolutely need these skills because after we wreck this world we're going to have to have people who kmow how to build from scratch.❤❤
So much work and on the fly decision making for a one off part. Great to watch it all coming together.
Artisan !! 👏👏
It is turning into a beautiful piece of art. I sure hope that the casting process goes well. Thanks, Dave!
Dave, the through holes are where the long levers are inserted into the capstan. The sailors push on the levers magnifying their force, and all of that torque goes into the capstan through those two holes. The bosses transfer the force into the ribs. On Tally Ho this capstan is used to haul in the anchor, and its chain. This can be a significantly heavy load, and without those bosses the entire casting would soon fail under the massive loads placed on it during use. It is trivial to imagine the anchor dug into the ocean bed at the end of its chain, as the full tide runs out. They want to go with the tide, and so the haul anchor. This could mean subjecting that part to tens of thousands of pounds of force. It just shows that Dave knows his craft, because he faithfully reproduces the bosses, even though he incorrectly thinks they are unnecessary. I _know_ how this part will be used, and the forces it will be subjected to would quickly break the casting without those bosses.
Going to be fun watching this come together across at least 4 different TH-cam channels.
Good man! Leo is slacking off again this weekend, just when he's started work on the rig, so I really need a fix of Tally Ho! related content.
Most of the time, Leo posts a video every 2 week, although lately it's been every week.
I know - I've literally watched every single episode of the restoration of Tally Ho! - my remark was intended to be light-hearted. @@phlodel
I love love love Dave Clark. I understand completely the joy and pleasure of hand turning wood on a lathe to produce something. I delight in the smell of sawdust. Sanding by hand is a comfort and provides deep satisfaction. Dave is a consummate craftsman. He strives for perfection because that is who he is. Dave gets deep satisfaction from making a nearly perfect pattern. AND most important, Dave understands that his profession is to _faithfully_ follow the plans. Dave knows full well that he may not entirely understand why the plans are drawn as they are but that it is his craft to turn them into a pattern matching the plans as drawn.
You and I are from the same school. I always tell my kids, " It's better to have a skill and never use it than it is to stand around looking at technology that failed or just won't do what you need."
I hope you keep posting pattern making videos. Your trade is underrepresented on the internet. The work is good but and the videos are getting better. Your speaking voice is even and a good speed. If you can, speed though repetitive parts rather than hard cuts. It makes the viewer feel included. You might want to have a whiteboard handy. You obviously have a clear picture in your mind but it's not coming through. I have a similar way of thinking and also try explaining with hand gestures but I often get blank looks. Looking forward to the next episode!
I love it when old school craftsmen share tricks of their trade, and you don't disappoint. Thank you so much Dave.
I find myself thinking "Which way is he going to measure/do that"? Because quite often I know several ways of doing that part of the job. Invariably the way you choose is one of those way - dating back to school days & early years at university, some fifty years ago (and rarely used in all those years).
As you said learning to do it "by hand" makes it far easier in years to come when faced with a broken machine and a tight timescale.....
Good to see the progress, thank you for the work 👍
Pattern making is such a beautiful trade.
We did like 9 weeks of "construction geometry" in my high school geometry class. Compass and straightedge, quizzes were copy this shape, draw a circle that goes through these points, enlarge this triangle so this side is twice as long, etc. I was pretty disappointed that my kids didn't have that in their geometry class, and realized that my high school had way better than average math teachers (except for 8th grade, where it was the football coach, who didn't know jack).
This brings back lots of good memories 🙂
Great stuff! I'm learning things, hahah!
The techy video/audio production stuff will come with a little time. No worries!
Dave, May you have a long life. you are a fountain of knowledge on an incredible skill set.
Only so many of us have capacity to capture
Watched a machine shop owner commenting similar. CNC is great but it is not the be all end all. He claimed there were many jobs that could be done faster more efficiently, using the correct machining tool and process.
Said he loses many jobs because they want CNC and will not consider any other methods.
Would that be Howee? th-cam.com/users/shortsan0sBVx9gOM
Thanks. btw when you jumped to fast film......with your hands right on the sander....I jumped....lol ya got me.
Wow you are bring back some old high school shop classes. My wood shop teacher always would want us to do everything by hand first just to try it out and ofcourse some kids would get it and other could not be bothered. Machine shop was done off a print that we had to make to some degree or another and only the seniors got to use the CAD machines. The good old days-ish 80's this has been fun following along and trying to remember everything they took us through and try to make all this stuff stick in your head....lol
Great work, Dave!
I learned this in high school 50-years-ago. Using a drawing tool, such as a plastic triangle, will never be as accurate as this method. This was known to Euclid, 2,300 years ago. His textbook, _Elements_ , teaches this as the 10th lesson. I have used it countless times over the years, because it is so much easier than using a plastic triangle.
Funny, computers basically saved my life. I have a weird quirk where my hands don't do what I want, I was bullied at school by teachers for my writing, for the presentation of my things etc. Using the computer to type removed this problem and allowed me not to be kicked out of higher ed. If I had to have any drafting skills I would never have been allowed to do mechanics, thankfully CAD systems were starting to be used at school by that time. It's the same when I build something, I can't cut straight, I have to sand/mud my walls dozens of times. I use CNC machines as much a I can, it's the only way to get from my brain to the real world.
Good information about using the extra block to keep things from rocking. Charles
Another craftsman from the „If you make it, make it beautiful“ school of thinking.
You really are a Doctor of Science concerning pattern making. Great Job. Thank You for sharing your wonderful knowledge with us.
“TALLY HO”
Very interesting to see, don't worry, you are doing good.
Great teaching of a fading craftsman skill set
Your doing ok on the videos. Very interesting project. Thanks for the videos.
Hi Dave, I'm similar age to you and really appreciate you showing these videos, using the "old school " ways, much the same as I learned back in the 70's doing my Marine enginnering Apprenticeship in the British Royal Navy. we did ALL our calculations on a Slide Rule- and even today it is quicker sometimes than a calculator. Tips and tricks are learned over time and are a valuable skill to be able to pass on to todays young engineers/craftspeople. Good on you for your simple to understand explanations.
Thanks for sharing your knowledge, Dave. I dont think I'll ever make a pattern but your woodworking tips are extremely helpful to any woodworker! Including me. You do great work. Thanks again!
Very cool!
That's a gorgeous piece of wood. Looks like something that could be an exhibit in an industrial museum.
Very nice work and the reasons for each part of the build plainly explained.
Now that is a disk sander, not some little toy.
Interesting process. Most people now of days would just 3d scan the original part, the use the cad program to fill in the broken sections. The next step would be to 3d print the pattern and off you go.
In other words, most people don't have your skill set and can't easily do what you do.
You are absolutely correct, learning these "manual", "analog" techniques will allow a cnc/digital person to know what the possibilities are, and maybe come up with a better way to produce a part.
I'm a 3D printer, laser cutter person, and I enjoy learning from your videos.
In navigating ships for over thirty years, it was important for navigators to know how to use old ways to navigate using sextants, alidades and ded reckoning because electronic navigation systems break.
I loved how you did this pattern and enjoyed watching you turn pieces of wood to make a new pattern
There is a fine line between explanations and ranting, here we have crossed the continental divide.
He needs a good film editor to make a good 15 min video out of this raw footage
Your presentation reminds me of a lecture from my high school shop teacher, Mr. Ashley, about how to do foundry work. It's important to know this stuff because computers suffer from the syndrome of garbage in garbage out. You have to know what's right, and that means being able to do it manually. Thanks so much for the excellent presentation!
Thank you for doing such a wonderful job on Tally Ho’s Capstan ! What you’ve done here will be part of a treasure which will be sailing long after we are both long gone, your an amazing Mechanic as they use to call craftsman pattern-makers in the day.
"Nothing beats working with these things right here!" You are so right! Mine are failing due to age and wear and tear. I'm glad I used them when I could!
I believe he is auditioning for a late night talk show host position! Yak, yak, yak!
Great job .
Great video , great craftsmamship. Really interesting to see how patterns are built up. Thankyou for posting and looking forward to seeing the next video
I really hope Leo appreciates how much time an effort is going into making this part .
I hope it's getting close to the pour it's really interesting but it is getting a little long .
Tally Ho is getting close to launch.
Oh, I'd say if anyone does, it's Leo. The amount of time and effort he's put into Tally Ho is nothing short of phenomenal, he knows what it takes.
It's painfully obvious why Leo picked this guy to do it.
Tally Ho is still years from launch. Leo said so himself like 4 weeks ago. He’s chosen to go with a talented craftsman who can make an old school capstan for an old school boat. The capstan can go on at the very end, I have no doubt that this part will be done long before Tally Ho is ready for the ocean.
@@tomdom_0143 At 72 years old i hope I'm around to see it.
Knowledge has no weight.....🤔😎🇦🇺👌
there is something that i do not understand, how is it that everyone that is involved in Tally ho is a top crafts man , is it the spirit of the boat ? is it Leo ? ... This is a master's job here Bravo mr Dave
Thanks for the lesson. Good stuff!
I love your process, Dave, and I am grateful that you are doing these videos. ❤🎉
Very nice work! Wonderful to watch and learn, I have examined old wooden patterns and marveled at the workmanship they took to make.
You are a true artisan. I really enjoy seeing how these things are done. Appreciate your skill set. Thanks for sharing.
The original part was probably made in the late 1800's , early 1900's, so you are just making the replacement part the same way they would have when the part was originally made, more or less. You are keeping with the pedigree of the part. This is great!
Very Impressive work! I love to learn new things!
Excellent learning experience for all. Thank you for sharing your experience and knowledge with us!!!
Thanks for sharing your knowledge, Video quality has improved a lot over this series.
I mean this as a compliment ... have you ever watched Mr. Carlson's Lab? If so, you know that he goes into great detail as to what he is doing, even to the point of repeating himself. What could be a half hour video winds up being almost an hour. I find his videos very entertaining, educational and informative. I can say the same about Dave's videos. I am a ham radio operator, so Mr. Carlson's videos are helpful to me. I'm not a pattern maker, but I do enjoy woodworking. I find Dave's techniques educational and captivating. Keep at it Dave ... looking forward to more of your videos.
Love this legendary handcraft! You will get there with the technology stuff just slow and steady. 👊
thank you for the all your hard work.
My grandfather came to the US. in 1906, He was trained as a pattern maker and worked for early car manufacturers a decide or so.. I was told he made car door bending jigs and the like..
I have a keen apprehension for hand lay out.. Thanks for posting your work flow skills.
that was a cool pattern
Your craftsmanship is amazing to watch.
Digital is great. It allows us to do cool things. Knowing hkw to do things manually/analog is a fundamental skill. Computers fail. Parts break. Batteries die. Switches and motors let the smoke out. It happens, and Mr Murphey will make sure that it happens at the least oppertune moments. You may only need that hand saw, plane, or chisel once or twice a year. But boy howdy when ya do, ya NEED it, and ya better know how to use it. Im really enjoying this series!
I’m a traditional patternmaker in australia, and for the last 5 years have seen hundreds of enquires about 3D printing patterns or moulds, and can confidently say it’s not cracked up to what it seems to be.
I worked at a pattern shop that ran a very efficient 5 axis CNC machine and also invested heavily into the 3D printing side of things at the height of all the “hype” maybe seen 4-5 foundry patterns come out of the printers, barely enough to pay for the material used, let alone the hundreds of hours of printing time, modelling and my god the hand finishing 😂
Then the foundry rips then to shreds getting them out of the molds.
I’m sure it’ll have its place in the manufacturing world further on.
Prototyping definitely and a good second set of hands to make intricate pieces for pattern equipment.
We just appreciate the efforts!
nice to see such great workmanship
I've been developing CAD software for long than I would like to say. I thought all engineers were 3D, until I started at my current place and we still have to produce iso, assembly drawings etc again I thought it users were just conservative and didn't want change. Recently I did some work with Cambridge uni engineering dept. And I was talking with the first year engineers and I should then some drawing. Joked that they might not know what it was. Nope they all have to have a term drawing 2D. Like punk I'm not dead yet.
Your right about learning how to do it with your hands makes a good foundation before you go on to cad and CNC
What people forget or don't realize is with many 3d printers you get jaggies
Dave, its nice to see your video skills, editing, camera, music, montage begin to catch up to your skills and knowledge in Pattern Making. Well done! It has to be a steep learning curve. I understand the benefits of painting the Capstan Pattern but hope once the casting is complete that it goes back to natural Mahogany, it was beautiful to see the grain structure when you were rotating it on the mill.
Nice job Dave
Its like listening to everybody loves raymond shop class
It should be noted. This pattern will be going to. A small foundry using traditional methods. Then to a vintage machine shop for installations the to a 1909 vintage sailboat rebuilt with traditional methods
Just wanted to say that the work you put into the videos is really appreciated and we understand that to someone whos built a career and a library of skills in a field completely different to videography and journalism, you will need to be forgiven if the presentation is not up to the standard of David Attemborough s work. Keep going; you re doing great.
Thanks Dave
Thank you for the insight you teach. But I don't think I will ever get my head around Imperial measures. We use metric it makes so much more sense😊. But the concept of the end product is amazing.
Remember your High School Geometry class? It's called a perpendicular bisector. Who knew it could be useful!
“My shop! My rules!”
Great to see Dave do it the old fashioned way. Hate to think of the day the GPS satellites are taken out and 10,000 sailors are out to sea and have no idea of how to get home! The sextant is a lost tool as are the HO 208's that make finding a LOP pretty simple.
Hail the algorithm
Going well now, both the pattern and the presentation.The mike positioning was spot on. One observation i have is that it appears that in the centre of the central boss of the top cap is a pressed in steel part that accepts the taper of the central steel shaft of the capstan.Its visible both on top view and from underneath.Couple of points on that.If Kieth at vintage machinery can reuse the original steel shaft, will he be able to press out that mating piece in the broken top cap and machine the new casting to accept it ? I'm guessiing here but i presume it needs the harder steel insert to rotate on to minimise wear of the softer cast iron ?
Honestly i am no enemy of modern tecnology, but anything but this would just feel wrong to use on a project like Tallyhoo since the whole point is exactly tis, to preserve old knowlegde alive. A massive thank You for sharing Your knowledge!
It looks like the webs meet the centre form at mappable locations. It also looks (from the angles I’ve seen) like they’re equi-spaced with the “horizontal” omitted.
So I would probably start by striking a 60deg inclusive off from the centre form and, if that’s close to the measured value, assume that to be the design intent.
What’s most important is to clear the mechanism - as you say, the webs are only there to increase rigidity.
When I'm listening to a craftsman, and I hear him point out how he could have done something better ( in this case, the audio ), I immediately trust him more. The part he thinks is right is probabyl near perfect.
Nice piece of music at around the 42:30 time code
Also remember that the old casting is busted up and put back together. It might not have reassembled perfectly. I'm interested to see how you model the bosses and fillets.
That geometry method doesn't give you a center, it gives you a perpendicular line through a predetermined point. If you had struck two arcs from the end points of the original line with radius greater than half the length of the original line, that would get you a perpendicular line through the center of the line.
He had the center
Great vid! Maybe you could consider getting a wireless microphone? Using their mic built into the camera is ... not so good in a bunch of ways. They start at about 60 bucks US.
You missed the wireless mic in the shirt pocket 😁
Grinding between two dead centers is the foundation of producing accurate cylindrical parts. I hear a lot of these CNC guys saying that dead centers are old school and live centers are the modern way. Not if you want true cylindricity with in .001".
Hey Dave, you're dealing with a welded up casting and you went to measure the webspacing first across a welded break, and then found the other side was a bit smaller ? How tired were you that day ? (learned my basic woodworking, metalworking & engineering drawing skills - including lathe & forge & some aluminium casting, - all both in imperial and metric ) in an English 'Grammar School' almost 50 years ago, aged 11 & 12 !)
cant wait to see how u part it for mold removal . over build then lathe outer sides?
Your skills as a pattern maker are obvious and I'm enjoying following this project. I gain far more from the visuals of you doing the work than from your explanations though. I'm not trying to be "nit-picky" here but there are far too many unnecessary words like "and stuff like that" for example for me to follow along with what you're trying to convey with your words. I get it, that's just how you talk, so I'm just tossing this out as food for thought. Nice work on the project though!
Guess I would have started with a 3D-Point-Cloud remodeling the piece and do a 3D-Print to make my cast. Great if one have the talent and patience to do it the classic way.
Yep! You are right about it. Kiss = "Keep it simple stupid"! And do the basics then go from there.
7:10 so ya filled a good piece of paneling with scratch marks by demonstrating the fifth grade geometry skill of bisecting an angle(a 180 degree angle) - - - and now you're gonna go get some mahogany and get on with the tally ho project
okaaaayyyy
