I have an old Craftsman (Companion) scroll saw Model 103.0402 with a modern Leeson 1/3 hp motor. The motor plate shows an amperage draw of 6.8 amps. I would like to have variable speed. Would using a speed controller intended for a router work? If not, anyone have a suggestion(s)? Any and all assistance appreciated.

Can’t use speed controllers on an induction motor. They are for universal motors like on a router.

I don’t know. They can’t be used on soft start motors, but I have heard of people using them on small drill presses. I haven’t seen it done. They go on sale at HF every so often for $10 or so. Try aand see. It can’t hurt.
