In this video I show the work I did to restore a wheel in a Chronometer. The wheel had been damaged and would certainly have been a candidate for replacement, but I wanted to try and repair the damage without replacing the wheel. See how I got on and let me know what you think of the results.

  • Everybody has already commented upon the superlative engineering skills. Can I add my appreciation for the superb quality of the video and commentary.
  • @pafurnace
    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.
  • @mfx1
    Nice work, it would have ben nice to see the soldering process as well.
  • This channel is severely under rated. You are doing an amazing work! Congrats!
  • @602br61458
    You are a true craftsman. Really enjoyed watching you detail every step. Thanks for a great video.
  • @mikebenda1061
    Excellent master craft skills,thanks. Gives joy that you found the “time” to keep it original. Your patience is calming. Great editing also.
  • @bkoholliston
    That's a very clever repair and the result is just beautiful.
  • @dippydipso5355
    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..
  • @bobdavis5216
    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.

  • Perfect job! Thanks for taking the time to let us into your world. I'm an instrument repairer so I love to see other craftsmen at work.

    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!
  • 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.

    Hi Tommy. Very nice repair work it should be good for another 100 years of service.
  • @624Dudley
    What a nice way of saving the majority of the original material. 👍
  • @aaceytuno
    Wow, that’s intense ! Better than new , didn’t think that was mechanically ever possible
