I would not have thought that sort of repair was possible! My clock work, compared with yours, is blacksmithing. I have no delusions of ever gaining these kinds of skills. Even so, your work is inspiring. It makes me want to do better work. And for that, I thank you.

One of the most unique, fascinating videos I've ever seen. The specialized machinery used to cut gear teeth is captivating. Thank you!! Very well done.

[@halnwheels]

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!

[@aaceytuno]

Wow, that’s intense ! Better than new , didn’t think that was mechanically ever possible

[@feraltweed]

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

[@TommyJobson]

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.

[@AppliedCryogenics]

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?

[@robertyoung7770]

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

[@TommyJobson]

The fit was soldered so it was about 0.005-0.01 oversize. The lathe is a Schaublin 102 with Schaublin dividing equipment.

[@campbellmorrison8540]

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?

[@BrainHurricanes]

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.

[@campbellmorrison8540]

@@BrainHurricanes Thank you really helpful, I didn't realise a module cutter would do this type of tooth, it looked longer than a normal tooth. cheers

[@aeroearth]

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.

[@TommyJobson]

It was a reel of ‘soft solder’ the rest is unknown!

[@deeranfoxworthy6069]

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?

[@TommyJobson]

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]

@@TommyJobson ooh!! I see!! Thank you for that info!! What about the teeth of the other tinier gear mounted on the "hub" of the ring-geared cog?

[@624Dudley]

@@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.
