I’ve been working on a big batch of stud earrings that are just bezel cups with a post soldered on. The issue I’m having is that when I have the earring in a wad of thermoplastic and run a silicone wheel around the edge of the bezel, the thermoplastic softens from the heat and I’ve inadvertently broken a couple of posts off because I didn’t realize how much the head was bending back and forth on the post as I push the bezel in.
Does this happen with Jett Sett and/or Basic compounds too when you generate a little heat on the piece? If it’s better than the cheaper “friendly plastic” I’m currently using its worth the investment, but if it’s just going to do the same thing I doubt it’d be worth it right now.
I’m not sure what else to do, short of putting my work holder in the freezer to re-harden it. I could, but tbh the time/interruption does not appeal to me. These are 6mm bezels at maximum and holding them in my poor arthritic fingers to set isn’t a sustainable option either.
