I use a piece of hardwood held in the lathe to hold a clock mainspring barrel concentric without damaging the teeth. The boxwood chuck is a really useful work holding technique that can be adapted for use with many circular components where concentricity is important and the component may be damaged by holding directly in a metal chuck.
NOTE. DO NOT WEAR GLOVES WHEN OPERATING MACHINE TOOLS AS THEY MAY CAUSE ENTANGLEMENT CAUSING SERIOUS PERSONAL INJURY.
I use cast brass here but you can use CZ131 brass as that is useful for riveting although I would anneal the brass beforehand.
Caution when drilling brasses as drills with a 'jobber' helix angle are likely to grab and may damage work or cause personal injury. In this video I 'back off' the cutting edge of the drills I use. You can use a drill with a low helix angle or straight flutes.
