Cheap motor for mash stirring
— This one has the opposite problem as a blender motor - it's way too slow, though the torque is probably more than adequate. I want something in the 20-50 RPM range. The wiper motor has two speeds, roughly 30 RPM and 50 RPM. The slower speed seems just about ideal, and several foot pounds of torque should be plenty.
