It doesn't need to be that thick at all Jef, 0.3mm will be quite adequate.
A hole punch like a Roper Whitney size 5 is best rather than drilling. For belts I use the imperial equivalent of 3.0mm for the rivet holes.
If you use the largest punch in the set to pop out the discs, you then change to the smaller punch to make the central holes, Quicker and cleaner than drilling and cutting circles out! :wink:
Then you dish them out in the doming block, but to be honest, they are naturally dished very slightly by the initial punching out anyway.
