Got to get all these questions asked so I will have some reading material when I get back.
Here goes. This is something I've been wondering about for sometime. I want a carving tool like a Foredom or there about. Just curious, I have a sewing machine motor with the foot pedal. If I could figure a why to hook a flexible shaft to it would it have enough power/speed for carving? I doubt if it has enough speed, I don't know what the top rpms are. It is out of an older Singer. I've kept this motor for years because I just know it has to be good for something.
