Thanks Everybody for the inpout on my project. I see I need to give more information. I am building what is known in the pottery and mold making world as a "Plaster Wheel". It is somewhat like a potters wheel but the wheel head is made of plaster, measures 24 inches in diameter and 6 inches thick. I have to have enough horse power to get this thing turning from a standstill, and to keep it turning under a load. The static load it will carry can be up to 100 pounds. It functions very much like a vertical lathe, but cutting plaster instead of wood, so there are also turning loads imposed by the turning tools. Speed control should be smoothly and infintely variable from 0-200 rpm at the wheel head. I'm hopping that I can get some sort of electrical speed controller that is like a potentiaometer which will allow me to just dial in whatever speed I want. That would be the ideal. Will consider other methods, though. Thanks John Rodgers 88 GL Driver John Rodgers wrote: > Fella's - and Ladies ....
