Re: Adding motor to hand crank extractor
> and an electric grinder might just get me there.
While the angle drive may be attractive, the motor speed may not. Handheld drills seem to have an RPM of around 3500, but angle grinders are often double (or more) that RPM.
A low speed, high torque arrangement will work best. That is what makes a motor (with the treadmill speed controller and an appropriate belt/pulley arrangement) from a recycled treadmill attractive.
I recently bought the key components of a new but stripped 21 frame SS extractor from Brushy Mountain's NC Bargain Barn. My original plan was to build the whole extractor, but getting a drum, honey gate, reel and associated bearing system for $125 was hard to pass up. I am still planning to use the treadmill speed controller/motor that I salvaged earlier.
