I think you are right and I may need to pay the high price for a single drill bit. The price of the drill bit is almost the same price of a new part. Sent from my iPhone using Tapatalk Pro

Mark, these are on eBay. Have you used these in the past. Sent from my iPhone using Tapatalk Pro

Really appreciate the help. Not sure how to anneal when the pivot is so close to the wheel and leaf gear, pinion. Sent from my GT-N5110 using Tapatalk

It was a micro drill used for PCBs I think. I could not find a small enough standard roof topped pivot drill. Sent from my GT-N5110 using Tapatalk

A book I have suggests that you need to anneal it as well but recommends not to if it can be avoided. As well, the part is so small and the pivot is in the pinion side so very hard to heat. And the new balance was working so well. Sent from my iPhone using Tapatalk Pro

So I failed miserably at drilling out the old pivot. It was way too hard the center before drilling it out. Any suggestions? Sent from my iPhone using Tapatalk Pro

Just when I thought I was done, I was carefully putting on the second hand on the wheel and the PIVOT BROKE right at the jewel hole. Disassembled it to have a look and it was indeed broken, leaving the pivot on the second hand pipe. So now I need to repivot the gear. Stand by for the next adventure....may make a movie as well.

Put the watch together and adjusted the balance to the round. Did rub on the balance cock so I took the lower pivot down a tad and it worked really well in all positions.

I would first take the balance off again and make sure the upper and lower jewels have no obstructions. Then I would see if the balance is round and flat. Then I would check that the impulse jewel is straight. If all this is good, check it the lower jewel is too high or past the setting, and if the upper jewel looks ok. Now if all this is good and you are able to shorten the pivots a bit using a jacot tool, do it. Last thing I would do is shim the balance, given balance staff is the right one, or the original. If you are nervous trimming the pivots, then shim. Sent from my GT-N5110 using Tapatalk

Thanks for the input. Read a boatload of books first, then bought the two video sets, tasconni and John Trope(spelling): I’m on a plane right now:). The I found the right material and gravers that were sized right. I also bought some sharpening plates off AliExpress for almost nothing. I should do a video on the tools needed. I now have 10 lathes. 5 on borel stands and the rest are traditional. Sent from my iPhone using Tapatalk Pro
