Ghettto small part holding. Not sure I trust the method completely, it was more of a self-experiment. My usual method is Clickspring style - CA glue thin washer like parts to a machined mandrel face with CA, do the machining. It holds well, but too well. I have to heat the crap out of the assembly with a torch probably +600F to soften & fail the glue.
Pics show hot melt glue alternative, no glue between part & face, just peripheral bead. It was rigid enough to hold part during (light = 0.010") facing & turning, even a bit off center. Then I just pull the glue off with needle nose pliers. Seems to come away clean without messing up material.
