I made a belt pulley from the left had thread cast iron flywheel/groved pulley that was on the treadmill.
I adapted the end plate of the treadmill motor to the mounting plate of the origional motor that adapts to the belt drive and adjusts the belt tension.
I replaced the broken fuse holder, that the origional owner of the mill had bypassed, with the speed control pot for the treadmill controller.
I can swap the origional motor back by removing 4 screws, and removing the speed pot, reinstalling the origional motor spacers and motor after the origional controller is repaired.
I have another 2 1/2 hp motor the same size I will eventually set up to fit my MicroMark lathe. And another one for the belt sander, and another for... Oh, it never ends.
Oh, the treadmill motor, driving the smaller pulley on the belt drive, runs steadily from 50 rpm to 2600 rpm! Woohoo!
