  1. A movie 25 cents a pop 10 cents and a bag of chips 5 cents, and that’s when I was a kid: 1967 to around 70. I’m 61 now. Sent from my iPhone using Tapatalk Pro
  2. I would use HP1300, or D5 Sent from my iPhone using Tapatalk Pro
  3. It is a very difficult job to straighten out a hairspring. I would recommend taking all the twists out first. Then I would start bending the round. Once it is flat and round, I would determine where the turn starts and make sure the angle up and then flat is correct and aligned to the stud holder on the balance cock. Then shape it to follow the regulator path. Sent from my iPhone using Tapatalk Pro
  4. Great job. I love making parts Sent from my iPhone using Tapatalk Pro
  5. Good work, I'll check it out Sent from my GT-N5110 using Tapatalk
  6. Take a slo-mo video of the balance with your iPhone and determine the amplitude in both positions. If there is a significant difference, then go to all the other advice. Sent from my GT-N5110 using Tapatalk
  7. I could use something like this to cut gears. Where did you get it? Sent from my iPhone using Tapatalk Pro
  8. I have done this number of times. First, years ago, it was a balance that I warped by tapping too hard when installing a staff. Then it was the occasional balance in pocket watches I was repairing that were “out of round” and also not flat. I got pretty good at Rounding and flattening balances. As well, I have had to flatten the arms in a staking set prior to bending the balance back to true. I have also adjusted the balance of the balance with the screws and washers. I have also undercut screws to adjust the weight. So I thought a video on this topic with some discussion on how not to screw it up in the first place, followed by how to fix it. And I have fixed a few. Sent from my iPhone using Tapatalk Pro
  9. So. Would you like me to make a video on how to straighten a Warped or Fouled balance using the proper calipers; etc? Sent from my iPhone using Tapatalk Pro
  10. As an Electrical Engineer, I am very impressed. Sent from my iPhone using Tapatalk Pro
  11. Here you go: Sent from my iPhone using Tapatalk Pro
  12. I depends on annealing and tempering requirements and what you what to do with the steel.if you heat up the metal to straw color and let it cool naturally, bending it is not an issue. Afterward you need to heat it and plunge the part into oil at just the right time to make it hard but not brittle. Lots of practice required. Sent from my iPhone using Tapatalk Pro
  13. Get a WW 8mm Pearless. Good lathe and easy to find on eBay. Of course, as was said previously, G Boley and others are always available on eBay. Some day I may sell one of my 13 lathes:) Sent from my iPhone using Tapatalk Pro

  15. I would look at the leaves of the center wheel pinion. Could be a small piece of dirt that could cause it to stop. Clean all the pinion leaves carefully. Sent from my iPhone using Tapatalk Pro
