My homemade RPC. It works well. I used surplus scrounged parts for not a lot of money. I have five three phase machines now. Ten horsepower is the largest. I put the RPC outside the main shop walls so I don't have to listen to it.
That bandsaw is a Cresent. It was made it the 1930's I think. I bought it from a machinist I used to work with,( I am not a machinist). His asking price was $250. I didn't try to get it cheaper!
