Hi
After seeing this Thread I used the information to motorize my grain mill in the same way. I just used a different switch and way to wire as you can see from my pics below.
I just used wire nuts for the Earth and Neutral wires.
Using a 3 way switch for the forward / reverse operation making it simple to wire as the hot goes to the center of the switch and then from either side of the switch to either side of the capacitor and then to the motor.
This also helped to keep it all neat and tidy in a box on top of the mill stand, which I can unscrew and move the motor to another operation if I need to.
I am thinking I may use the motor to also motorize an apple chopper for a cider press making it interchangeable between apparatus.
Hope this Helps
