2 ?s. First, do they sell it w/o a motor? And Second, will it take a larger, variable speed motor? I'm currently using a 1 hp I got from Koval eight or ten years ago, and it's fine for 3/32, maybe 1/8, but if I work on 5/64", or even large 1/8" blades, I can bog it down. My next one will have to have more HP.
