"Knurled knob slides in a slot, a quarter turn locks in the rpm's". I see a knurled knob on the right side, but I not only do not see a slot, but how does this knob influence the rpm's? And is this a DC motor where "Motor leads switched to run counter clockwise" makes sense?
I like the source of the motor, esp since I have a few household vacuums that I could canabalize for the motor. But besides the source for a motor, this project isn't making sense to me with just one picture and just a few sentences.
I obviously missed something important. Could you illustrate more and/or explain more?
