At first, I intended to use built in spacer bearings, so I could clamp down on it all with torque. Then, it started to become clear to me that clamping down, shoves on the bearing in the gear, not on the wheel bearings alone. Has anyone used torque, instead of only enough thread to retain, and not wobble?
Can a spacer be found that will do likewise to the gear, so that you can crank down on the bearings?
To add, perhaps it is somewhat of a nonissue, as the gear is aluminum, and the bearings stay square to the wheel, just by close machining.
