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.

Solved 1. As the PB1 is pressed, MV1 opens and the water

Question: 1. As the PB1 is pressed, MV1 opens and the water begins to fill the tank. At the same time, the stirring motor M starts operations. 2. When the water level passes TLB2 and reaches TLB1, the MV1 closes and the stirring motor stops. 3. Next, MV2 opens and starts draining the water. When the water levels drops below TLB2, MV 2 closes. 4.
