In this video, I cover the process of making a replacement wheel for an antique clock, start to finish.
The clock is a rather nice 18th-century quarter chiming table clock and the existing wheel was a poorly made replacement. The client wanted a more appropriate replacement making.
I have broken down the topics covered and linked their place in the video so that you can jump to each specific process as it interests you.
0:00 - Intro
3:01 - Wheel and pinion theory (Maths)
14:23 - Preparing cast brass
22:21 - Cutting the teeth
34:07 - Crossing out jig and marking out
37:40 - Crossing out
39:53 - Mounting the wheel
41:29 - Spin riveting

    My goodness great video, not sure I blinked for almost an hr. I not only enjoyed watching your machining technique but especially enjoyed the math portion for calculating the correct module. I truly appreciate you sharing your profession with us and look forward to your next video.
  • This is beautiful. I’m a machinist and this definitely isn’t machining this is ART. You are the last of a dying breed just beautiful craftsmanship all around.

    Those of us who are watching these videos, do not care how long it takes. Lol, most of us are here because we're ocd, detail oriented, care about precision and accuracy. Clear and Thorough, screw concise.

    Thank you for keeping our profession going!!! I have retired years ago but you have rekindled my memories! Be proud of yourself! Excellent.
  • @welshpete12
    I'm constantly surprised what I find on YouTube . Absolutely fascinating , and such high standard of workmanship . Thank you for posting
  • @jeffs5072
    Clean precise and as close to original as possible. So much time, patience and skill to make a wheel. Makes one appreciate when you find an antique clock movement that is entirely original.
  • @fredleonard1547
    Wow I wish I had access to the cutting gear you has when I was repairing clocks a few years ago. I'm well retired now but in 60s to 90s repaired many hundreds of clocks from small to large town hall type's. Many old grandfather's had damaged wheels and broken teeth that had to be replaced by hand. Lovely video thanks. Fred.

    Fun to watch, reminded me of when I was a wee baby boy. My Grandfather was a clock maker. Brought back some very fond memories.
  • Really enjoyed the whole video, someone who really knows what they're doing, with a whole load of high-end tools and is prepared to share their knowledge. Much appreciated, thank you.
  • @dmmdmm5435
    Brilliant and Well done ! As a metal sculptor and welder/fabricator/ machinist I appreciate your sense of aesthetics and clear narration.
  • @rogers531
    I love making things out of Brass for broken pieces ,, the pinion leaf had sheared to halfway and was sitting on the next leaf. I just happened to spot it after cleaning the mainspring. Your precision workmanship gave me a boost I needed. You're a credit to us all
  • Fantastic Tommy! I really appreciate you talking through your decision making in the finished cut. It really helps to know not just what you did but also why.
  • @djkulp1
    Very fine and accurate work. It is such a joy to watch such a perfectionist at work.
  • @feliciapeach
    As a Grandfather Clock (x2) owner, enthusiest & former Diamond Setter, I very much enjoyed your video & can relate to many.of the skill set, and I understand the work involved. Thank you!
  • That was fascinating and not too long at all. If you want to know the thought processes behind each stage, then your video is just the right length. Well done Tommy!
  • Enjoyed the video, it took me back to being at my Grandfathers in Ireland back in the sixties, repairing watches and clocks were his trade.
  • @Rocketman88002
    Long before I decided to make my living in the electronics field, I sat ir stood by my uncle's rolltop bench where he repaired clocks and watches; a trade he learned from his Dad. I have always been impressed with horologists. They must apply math, trigonometry and physics when designing and making parts. This video has been fascinating and I could watch ones with this content for hours!
  • @pnwRC.
    Fantastic video! I appreciated where you showed us the steps you took to calculate the proper dimensions for the replacement gear.
  • I must say your craftsmanship is superb, even to this untrained eye. Thank you for posting your work. It’s absolutely fascinating.
  • @olgreywolf9688
    Utterly astounding. Have always wondered how such small, precise, detailed work was done. You've illustrated and demonstrated it so well, from the calculations to the end product. Thank you for publishing it here. Can't help but wonder how a clockmaker in say, 1500s, might have achieved such results, close enough to make a clock even function at all, with such primitive, non-electrical tools! I can't even put four boards together and have them all come out, "right". How you might cut a multi-toothed gear wheel and have the last two teeth 'come out' so precisely .. is, to me, an impossible feat. Fascinating, very, very enjoyable hour .... thank you!!
