Step 8: Geared
This unit is using the chuck and geared hub from #1, just reversed.
The gear on the motor matched the gearing from the chuck/hub.
I mounted the motor and chuck/hub to a thin metal plate, then bolted the plate to the windmill.
I used 4" PVC pipe and caps to enclose the motor and chuck/hub.
I'll experiment with blade designs for both speed and torque.
I installed 4 larger blades made from 4" x 2' PVC pipe.
