Excellent video, you explain some of the finer points that are often neglected, like how to hold the burnisher, in other Jacot tool demonstrations. One improvement I’d suggest is your use of oil. Oil is very important when burnishing, and its purpose is to carry away the fine metallic particles that are produced during the process. These are the black particles you wiped off the burnisher in this video. If these particles are not carried away, they make it very difficult to achieve an optimal result. For this reason, I suggest that you oil the burnisher, and not the runner/pivot, because this will provide sufficient oil to carry away these particles more efficiently. Your advice regarding choice of oil is excellent. Any fine oil that won’t evaporate and run dry due to the heat of burnishing is ideal. Lavender oil and light honing oil are ideal. I know a lot of watchmakers in the USA recommend Hoppe’s gun oil. I suggest you apply a light film of oil to the acting surfaces of the burnisher, instead of oiling the pivot in the runner. For anyone seeking further information regarding burnishing pivots in clocks and watches, I highly recommend an article you will be able to find online, that is written by David LaBounty.
You mentioned that you are right handed and therefore purchased Bergeon Burnisher 2933G. However when I shop for that item, I see it listed as Left Handed burnisher and the 2933D is Right Hand. I don't know if that was a mistake or if I am not following the logic of how these tools were designed. I am left handed and would have expected 2933G to be for me.
For Jacot Tool work you will need the 2933G (listed as for left handed) if you are RIGHT handed. So, it was not a mistake and the reason I pointed it out.
Very helpful video thank you. How do you rate sapphire burnishers instead of the traditional metal ones for this kind of work? I am new to pivot polishing by the way.
Sapphire burnishers work very well, but it is important to understand that they are not for use with a Jacot tool. Jacot tools should only be used with traditional steel burnishers or the Bergeon carbide burnisher. No stones, abrasives (such as diamantine or diamond paste), ruby or sapphire should ever be used with a Jacot tool because it will ruin the runners and lanterns. Sapphire burnishers can be used when polishing pivots on the lathe and with the large mounted pivot polishing tools where the burnisher only makes contact with the pivot, such as the Levin and Dorrington style pivot polishers.
@@mercuriall2810 I agree! I've heard that sapphire burnishers grind down the area on the runner surrounding the pivot. The Bergeon burnishers are made of tungsten carbide, which lasts a very long time and is very efficient.
Great video VW! Very precise, to the point, and complete! I can't wait to try this technique! Thanks for making and posting the video!

Thank you very much for these additional insights!
Terrific video!
