I had no plans. It is just a 1” piece on edge with a thru hole using bronze bushings. The rod through it threads into a plate the motor is attached to. I used a motor that was used for bbq spits and turning demos. It comes with its own controller. Just don’t use it with a noisy cutter motor. It has screw holes on both the motor and the gear box. I used the motor holes to attach to the hinge plate and attached a handle to the gearbox. 8 made a hook like David’s to catch the handle. Check the pic in the media and all should be apparent.
