I still think the shim foil affected the tightness of the set screw, and it loosened slightly during high acceleration rates while reversing directions. It could also be that the hole for the set screw is slightly worn. I just know using loctite fixes the problem and it doesn't come loose any more.

With a flat you should be able to make a modest setscrew work without all the hassles. Round shafts are good for things like volume control pots. Flats or keys are much better when you need to transfer significant torque and power. Does your motor shaft have a flat or is it round?
