Anybody have a cool method for holding a bangle for inside lettering? Is there something like an extra-large ring fixture out there? Thanks!

thermo lock would hold it nice and tight, it molds around it and holds it tight in your vise.
far easier to engrave it in the flat, then go ahead and form it. tape the engraving to protect it from dings & scratches. grs makes a super handy metal former for that.

Monk, a bangle is a closed circle. If you engrave it flat it has to be rolled up and soldered back together. (Firescale can be a PITA for someone who is not a smith)
If it comes into a store workshop on a ladies wrist, you have to cut it and flatten it if you want to do it the "easy way".
Then roll it back up & solder. Kinda hard to do if it's made of hollow material....
If you have access to a lathe you can turn a fixture outta PVC or Delrin in a few minutes.
If you don't, I made a holder of sorts out of a 3" to 3.5" piece of steel pipe with 1/4" thick walls. Split the pipe into 2 sections.
That was before Thermoloc, so we used one of the thermoplastics to line it with. I think it was called Aquaplast? Formed in hot water.
You can use a hose clamp (kinda hard to find in that size) to hold the thing together...
You are grabbing the 1/4" thick steel, not the bracelet - which is held in place by thermoplastic.

If the bracelet is a heavy enough gauge to take the pressure of the vise, I've just clamped it between thin wood blocks or sole leather when I was in a hurry. Judgement call.

brian:tyvm for the correction. i make the open type for a woman that operates an outlet for jewelry made by hand. she called them bangles, so that's where i picked up the term. btw-- thanks for the info on making one. there may be others wanting to try such.

Glue inside slightly oversize chunk of pvc?
Clamp by the pvc..
Or drill hole the size of pv pipe through some Teflon, or nylon, sit that in middle. Cut a socket so it can form two strips. This will serve as keepers for strip of nylon your bit of pipe is running through.
The nylon strip (1/4"- 1" depending on what size bangles you have) is clamped in your vice.... The pvc is snugged up against the top of the vice just to the degree that it has enough drag to hold, but that you can muscle it to turn without loosening the vice.

Water expands when it freezes... it would more than likely distort and/or burst.

Why can you just use plain old engravers pitch?
