Thank you for the time you put into making the videos, much appreciated from the other side of your camera. Nice to see a repair rather than a replacement, especially one so skillfully done.
I had the pleasure of using both a Schaublin 80 and 102 at a prototype machine shop back in the 1970s.. I agree with everything you said about the tactile feel of these machines. The 80 in particular, was used by a machinist who I watched make pressure diaphragm caps that were .080" in diameter with various diaphragm thicknesses as thin as .0012" across the diameter. I was at his house one time where he showed me a clock he made himself with a siderial complication. It wasn't until later in my life that I came to realize how close I was to a very special talent. This video brought me right back there. Thank you!
Flabbergasted frankly. So glad I found this channel. The workmanship and video production is stunning. I also love the sound of that clock in the background.
I just had to watch after seeing the title of this video. I took a two year class in watch and clock repair about thirty years ago in plainwell Michigan. One of our projects was replacing a tooth on a wheel. I told my instructor I could replace all the teeth and keep the wheel. He looked at me like I was nuts. That night after school I went back to class and did about the same as you. However instead of making a blank and recutting all the teeth I cut another wheel of the same kind so the new ring gear would solder nicely onto the turned down original. It did not look as nice as yours but it worked fine. I think my instructor was impressed
I just had a flashback. As a joungster I built tiny mechanical devices for optics to be mounted on a satellite. We haven't had such good tools and some pieces were extremely challenging to make.
Hi @jimad and @PatrickSpencer, unfortunately I had a nice clip of setting up the camera and no footage of the soldering part, so sorry for the omission! I basically sweat the smallest amount of solder at the lowest heat I could manage to get it to flow taking care to shield the pinion to prevent heating it.
Perfect Tommy, you are a master, you have beautiful machines. I wish I could work like that. It looks beautiful and I'm a little jealous of you. Kind regards
I say that the whole video is played backwards to trick us! Joking of course. Very nice job and I'm now going to check out the other videos on this channel.
Superb skills indeed, I spring to watch. I would love to see the Gents Pul syn etic master audible in the background ! Not of the same fine quality but built to last. Mine was made in 1931, has been installed at home now for 36 years and keeps excellent time, within 2 seconds per week.
Amazing patience and intricate work. Have you weighed the before and after to see if it weighs the same or very closely? I was wondering on such a delicate gear if the weigh would change the operation... IDK But Thumbs Up for sure...
Im curious as to in what cases this type of repair would be preferred over making a new wheel? Detailed wheel repair where it would be difficult or costly to replicate perhaps?
Wonderful work. You must have spent a lot of time getting to this stage! Where did you find that beefy pair of tweezers? Got to say it again, wonderful work.
Gorgeous repair! Curious question though, do you have to worry about the inner teeth being clocked or aligned in a specific way with the outer teeth you've made? Or would the orientation have no bearing upon the functionality of the mechanism? But if they do, how do you align them or set up the jig to be sure it's aligned?
Thanks, and a great question. On this wheel the inner part is known as the crossings. These are partly decoration, partly weight reduction to inertia, they don’t need to be clocked to the teeth.
@@deeranfoxworthy6069 I think you’re asking about the orientation of the repaired gear to the pinion with which it shares the shaft. The relationship between these two components can be random without affecting timekeeping.
When doing something like this, is it important to recreate the original angular offset between the outer teeth and the pinion teeth? I mean, can you just start cutting the outer teeth at any angle, or does it need to be referenced to a tooth on the pinion?
That is amazing, Ive never seen such a repair. Im a home machinist, I make some small parts but this is on a whole new level. Where do you buy cutters for teeth like that or do you make your own?
If you search for video "Chronometer Train Wheel Repair Part 1" go to timestamp 19:40 there you can see such a cutter, so you might be able to search it. Good luck.
What type of solder did you use to attached the rim to the wheel? When fabricating small parts out of brass I prefer to use high temp silver solder containing 45% silver. When fabricating model aircraft tanks from tinplate I use low temp silver solder comprising 97% tin and 3% silver. Some 50% stronger than traditional 60/40 lead solder yet melts at a lower temp around 220 degrees C. If you used 45% silver solder to attach the rim you could make a heat sink out of aluminium or copper clamping on the wheel spokes to avoid tempering the pinion gear and shaft. Another method could be to bevel the wheel edges then swage the rim into the beveled edges and then face to final width. Likely add three brass rivets at the intersection of rim and wheel with rivet holes countersunk each side which would ensure the rim could never slip on the wheel. Avoids heat and the risk of distortion.
Excellent work and I see you have all the machines required. What was the size shrinking fit and the name of the manufacturer for the lathe and dividing head etc? Regards Bob
I am also could not see that seam - and I also was missing the actually prozess of making the comination between that to wheel 's. Not only 1 picture about that connection process was to be seen.
Would it be possible to clean the gear surface the teeth and protect the wheel area and electric plate a thick layer of some sort of metal on that Andre machine the original gear profile I know it's just a general question I just wondering if that's possible
Everybody has already commented upon the superlative engineering skills. Can I add my appreciation for the superb quality of the video and commentary.
My boy watches Clickspring. You can just tell.

Thank you that’s wonderful to hear.
This channel is severely under rated. You are doing an amazing work! Congrats!
Agreed, this is quite possibly the best clockmaker channel on TH-cam.
Nice work, it would have ben nice to see the soldering process as well.
I agree, I wanted to see that as well !
Where art meets engineering - Just beautiful. Thankyou
I am in awe at your work. Brilliant. Thank you!.
For me to attempt this operation I would have use a lump hammer and a cleaver..
That's a very clever repair and the result is just beautiful.
Excellent master craft skills,thanks. Gives joy that you found the “time” to keep it original. Your patience is calming. Great editing also.
A Masterclass, just a pleasure to watch and lovely workshop
What a pleasure to see a craftsman at work, it truly was inspiring to see. Excellent!!! Subscribed
What a nice way of saving the majority of the original material. 👍
That old lathe is beautiful and astounding
certainly looks like a splendid job well done, also well filmed and narrated.. makes me want to send you my favourite verge fusee pocket watch..
This video gives me hope that a few percent of people have escaped the dumbing down of the last 50 years. Please keep it up!
A very salient point, not often made.

Wow, that’s intense ! Better than new , didn’t think that was mechanically ever possible
Hi Tommy. Very nice repair work it should be good for another 100 years of service.
Thank you for taking care of our heritage. Salut from Vallée de Joux.

That's some beautiful gear! Both the clock part and the shop equipment :)
Excellent work! I would like to have seen the soldering procedure use on such a heat sensitive component.
This is becoming a lost art. Well done.
Masterful job! The order of operations was surprising.
A great visual explanation of the whole process.
I just suscribed.... your work is lovely❤ ....old retired dentist
I've always thought that dentists would make excellent clockmakers/repairers, also jewellery creation and repair.
Wonderful work 🙂
Beautiful job of restoration! Always a pleasure watching a master craftsman work. The precision of watch and clock work machining always astounds me!
Mesmerising
Thanks for the video, helps a lot! Appreciating the engineering, video and audio --Thanks
Excellent work

SIR. congratulation you are a real proffessional.that is a master piece. BRAVO.
Very well done!
What a brilliant solution for repairing that wheel! Excellent job with the video as well! Congratulations!!
Just amazing!
Congratulations from Brazil!
I just love watching your videos Tommy, many thanks.
brilliant, so facinating.
Wow!

Well done.
This video just popped up on my suggestions this evening and I am happy for that! Wonderful work. So good to see repair instead of replacement.
Super work Very impressive
Nice video. Thanks for taking the time to share it.
Super job! That lathe is special.
Nice job!
Very impressed with your work. Looking forward to seeing more from you!
Wonderful job! Could you share a few words about the soldering process - must have been quite tricky. Thanks for sharing your work.

hi, your videos are very constructive. I wanted to know how you welded the rim to the wheel and with what material did you use, thanks a lot
oh yes , a secret also for me *: - {* . . .
Very pleased that The Algorithm has finally suggested your channel. 1new subscriber 😊

It was a reel of ‘soft solder’ the rest is unknown!
Excellent work and I see you have all the machines required. What was the size shrinking fit and the name of the manufacturer for the lathe and dividing head etc? Regards Bob
The fit was soldered so it was about 0.005-0.01 oversize. The lathe is a Schaublin 102 with Schaublin dividing equipment.
Beautiful repair. Honestly on camera, I couldn't see the seam.
I am also could not see that seam -
and I also was missing the actually
prozess of making the comination between that to wheel 's.
Not only 1 picture about that connection process was to be seen.
Nice to have all that you need . piece of cakies
I'd never make it as a clockmaker; I can barely even see the problem! :D
Would it be possible to clean the gear surface the teeth and protect the wheel area and electric plate a thick layer of some sort of metal on that Andre machine the original gear profile I know it's just a general question I just wondering if that's possible
