Replacing roller jewels when combo tool won't fit?

Greetings all. I'm in the process of attempting to replace a roller jewel in a extra-thin Illinois pocket watch, 12s+ grade 439, IIRC. There is very little space to get the jaws of the combination tool onto the roller table to hold and heat it up. I have the hole cleaned out, and even if I do get a tool on it there will be trouble getting shellac on the top of it to start the process. Since I'm pretty sure that the pocket watch combo tools that I have wouldn't work on wrist watches, what do you guys use for this purpose? Do you just replace the whole assembly, table and all? Thanks ahead of time. Cheers.

I'll try to post images a bit later. Thanks again.

A heating pan might work where you could heat up the roller table with a shard of shellac and then drop in the jewel. It's indirect heat you are looking for.

      Balance cock stud screw

      By Neverenoughwatches · Posted

      As Richard said, this is a really old school trick for joinery.  Cut i strip of paper, might need to be watch paper  around 1 " x 1/2" lay it over a staking block then press the stud screw into and through the edge of the paper upto the head of the screw. You probably wont even need to pull the paper away the head will pull itself through.

      Waltham 6/0 d winding stem

      By ooteenie · Posted

      Hello,  i am looking to source a winding stem (winding arbor) for a waltham 6/0 d movement. I have found some that claim to fit 6/0, 6/0s, 6/0b etc and somealso claim they will also fit the d as well. The d does have hacking which is driven by the stem seating completely. Given some of the costs of these, i was hoping someone would know of any interchangeability with a source, or know a source where a confirmed 6/0 d stem can be had. I am in the US so a US dealer is best.    thanks in advance.

      So great to see and hear- your mum looks great! …my mil had a stroke last summer in the golf course parking lot. I’m flying out tomorrow to visit and play golf. she’s ornery because she can’t get off the tee but I hear she makes up for it on the greens since she’s been putting since a week after her stroke 🧐…
