Did you try an AndyMark bearing in the same bores that you displayed the runout in your first shot? Did you independently chuck the shaft and hub in a lathe/drill press/something else that spins to verify that each component spins true? Without all 3 of those actions, there's no way of isolating the problem to your bearing.

The bearings fit on the VEX .5" hex shaft snug. On a cnc'd one piece bearing block the shaft would not go all the way through. I've tried most of the bearings and both VEX Pro and AM hex shafts.
