Hi JD, we like your video, we are watchmakers and have been doing this work for 25 years for friends and family, we are actually micro-machinists. It is nice to have you here, and to have discovered your channel here on KZfaq, you are very patient, a lifetime of patients is required to do this work to say the least. This is just a quick hello we will subscribe now and see what you are up to currently.

Hi Jd, I reviewed your video again today. I just wanted to thank you as I had forgotten about the pivot gauge for determining the correct fit of the pivot to the tool. This gauge makes this determination much easier than "guessing" what the pivot fits into the tool! Thank you again.

Thank you for your excellent tutorial. I recently acquired a Jacot tool , it was in a poor state of repair, but have tidied it up and now with your explanation I will be able to put it to good use. as hobbyist clock repairer the squaring off the end of the pivots will not be necessary and that helps as that part of the old Jacot has been broken in all cases - but the rest will be of use now I know how to use it and its limitations, fine for clocks but not so good for watches. So thank you for the in depth explanation and detailed closeups. a great video.

great video, from what I have seen, the way this is powered is to use the pulley system from the watchmakers lathe, NOT the motor, but the intermediate system, and put it's crank handle in that spindle, and turn by hand, like an old singer sewing machine, or like the aforementioned singer, use a cast foot pedal system ( using the 'file' like you would in large scale in bench work, two handed).

JD the way it is designed, from what I have seen from Steffen Erich Pahlow's site is that the rabbet on the base of the tool can fit on a pedistal, for the older lorch and other lathes, it is like a wine glass stem, with two flat screws holding the lathe bed to this plinth, this jacot tool has the same rabbet on the base, as these smaller lorches do, so my thinking is this is how they mount to the motor unit, and use their rubber belt to drive the dog on the tool.

Cool video and useful for showing the setup of the tool. I am a novice like yourself, but I think that your theory of flattening the pivot ends is incorrect, or at least doesn't apply to escapement parts. I realize the wheel you have in the tool isn't a balance and may or may not ride on a cap jewel, but on any pivot with a cap stone you want a domed end surface to minimize the friction in the dial up and dial down positions. The pivot end should have has little contact area as possible, which is achieved by making the ends into a dome shape. Adjusting a watch for position sometimes involves making the ends slightly flatter to reduce rate in dial up or down by adding friction, but generally speaking I believe you strive towards a rounded, polished end. I love your channel, BTW.
@JDRichard5 жыл бұрын
hugeshows Thank you very much for the comment. I now know this as well and rounding out the parlance staff pivot is a necessity. I actually need to do this today on a movement I was repairing, as the amplitude is poor when the balance is putting friction on the lower jewel I just replaced. Hoping to fix this by reducing the pivot slightly and rounding the pivot end. I will keep adding videos until someone says they hate my videos:)
@hugeshows5 жыл бұрын
@@JDRichard Good luck and if you find that rounding the pivot isn't helping, check the depth between the hole jewel and the cap jewel. If it's too much endshake there, the pivot can start to rub the flared part against the hole jewel.

I realize this is an old, old video, but I just wanted to say, great video, JD. You always show the baby steps I like. Every detail. BUT...I am going to give my opinion some may not like, but I am saying it anyway: someone needs to make a modern motorized device for doing this instead of relying on these antiquated contraptions. Necessity is the mother of invention, and since watchmaking has pretty much died out as far as innovation and advancements in tool technology goes, we're left with the old ways. Besides, they no longer make these tool, do they?. If they did, Bergeon would want $50000000 for it. How old are these Jacot tools like the one you have?.

I think you can burnish a small pivot. Use plenty of oil to prevent overheating the pivot. As well. Choose a deep pivot trough to ensure only a small percent of the pivot is exposed.

Hi JD, love your videos. I've recently taken up the hobby, been working on a bunch of Elgin 12s 7 jewel movements -- only the balance has jeweled holes. Low amplitude < 180 deg. is a common characteristic, even after cleaning. I thinking that polishing the pivots on wheels might help, so a Jacot tool seems to be in my future -- thanks for the tutorial. But what about polishing the pivot holes, how would that be accomplished? BTW, I'm a fellow EE, I've found others in the hobby --- interesting that we gravitate to this sort of thing. Best regards, Dan

Use peg wood sharpened at the end and rotate in the jewel holes. It’s called pegging out the holes.

@@JDRichard Thanks, in some cases the pivot holes are a bit rounded out, or even oblong. I'm aware of a couple of solutions: one being doing a bushing (requires a lathe and skills I do yet possess), the other is "closing the hole" with a staking set which i do have. MIght you have a video on the latter?

Hello JD Richard, Is it possible to use this tool to drill a hole and remake the pivot? For example, repivoting the escape wheel on a platform escapement? I'm guessing this tool is mostly for polishing the pivots? Thank you so much for the video!
@JDRichard3 жыл бұрын
The short answer is No. You really need to pick up a pivoting lathe, or attachment. The trick is to align a very small pivot drill with the shaft to drill the hole and that cannot be done on a jacot.
