Gene, I wanted to be sure that you picked up on the fact that the setscrew is inserted ALONG the thread pitch line PARALLEL to the axis of the shaft but offset from the shaft axis by the radius of the shaft. So it in essence forms a round key that CAN BE removed without applying an oxyacetylene torch. Believe me, with all the best intentions you will probably want to remove the pulley at some time during the fabrication/modification phase.....I certainly did.
PLEASE!!!!! Don't use Locktite. Think about how you are going to hold the armature and shaft to keep it from turning so you can unscrew the pulley after you have toasted the front bearing and probably the windings and commutator. >I have a machine with a similar setup, treadmill motor, screwed on flywheel. I screwed the flywheel on snug, drilled a #6 hole .75 inch deep parallel to the axis of the >shaft but on the pitch line of the two threads, tapped it 1/4-20 and screwed in a 5/8 inch long 1/4-20 socket head set screw.
