Re: G10 strength
Original poster: "bob golding by way of Terry Fritz <twftesla-at-qwest-dot-net>" <yubba-at-clara-dot-net>
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.
