Oh wow, that's exactly what I was wondering. That looks great! What's the actual diameter on the ball bearings? I know in commercial bearings, the inner and outer races are cut into a concave path so that the balls automatically center in the path. What made you choose to do use parting cutter? It'd be easy to hold tight tolerances on the depth with, but it'd leave a flat bottom in the groove. Are you guys seeing any issues with the balls catching or jamming since they can move side to side relative to each other and since you don't have an inner cage?
