The comments on fibre discs earlier in this thread reminded me that I
had some 3mm thick PCB laminate, which ought to be pretty good. A few
layers of this (with the copper etched off, or partially etched to act
as a heat spreader), or normal 1.6mm laminate screwed/glued together
should make a nice strong disk with good insulation and temp
performance.

Why not cut roughly to size (even square), mount on the rsg motor and
use the motor itself as a lathe to cut the circle shape - no centering
problems!
