Thanks Paul. I have been doing lots of looking on the internet and get lots of good ideas. The swivel turntable idea comes from an early 1900's large mirror grinder. Been in all the local bookstores and can not find a copy of ATM book. To produce a truly random grind, 2 motors would probably be better then. Will have to checkout the library.
