Thanks for the reply Kurt, I'm afraid that's going to be beyond my technical knowhow at the time being. I'll keep studying. Would like to use it eventually, thing's huge, like 30 inches long and a foot in diameter.
I did manage to find a dc shunt wound motor in a local Amish fellows shop yesterday though I can use to help me up the learning curve a bit. 90v, 1725rpm...gotta be good for something.
Thanks though.
