Greg
i am using a 12" x 1/2" G10 disk with 8 electrodes on a 10" pcd. cant 
remember the weight off hand but i worked out it was 30 kilos of 
centripetal force per electrode it has spun happily at up to 4000 rpm for 
about a year so far with no problems. it is inside a blast shield just to 
make sure tho. normally it runs at 1000 rpm  for 400 bps. hope this helps. 
there are pics on the web somewhere.

cheers
bob golding.
