Thanks again Al. I appreciate the comment about "being repaired". I've also found the quality and finish on some of the American pocket watches to be of varying standards of quality and finish, although I'm probably more used to later Swiss movements.
Ideally I would remove the old jewel from the chaton and turn up a new one on my lathe. However, my lathe, and my skills, are probably not up to the task, although finding the correct gauge of brass from hobby/model maker shops isn't that hard.
I agree with you about keeping everything as original as possible, and in this case I've kept the balance original and used a jewel from the donor movement as it was in better condition than the original. Unfortunately it exhibited the same loose fit, so I could either stake it in with a pin punch
馃槻馃槻馃槻, or try retaining it in a more sympathetic manner.
So, here we go:
After cleaning the jewel and the balance cock again I set the jewel gently, mounted it so I could view it under the microscope and then applied bearing retainer with a Bergeon fine oiler and allowed it to wick in to the circumference of the chaton.
I'll give it a full 24 hours to cure although Im sure it won't take that long to harden.
Finished jewel looks much better than it did before.
