Hi bromikey, thanks for the positive words.

I don't have smaller magnets on hand, though I can always build another rotor later.

I picked up some parts from hardware store to make the motor arbor.

Unfortunately, the threads on the top part of the motor I was hoping to use. are reverse thread, so the nut coupler can't just be threaded on.
So I found a 3/8" coupler that is fairly snug over most of the shaft, so I bored a set screw hole to make contact with flat part on shaft, just need to pick up a tap and die kit to tap the set screw hole.
Was also working on the PWM motor controller circuit, it works well.
Here is the circuit.
peace love light
