Fixing gearbox assembly inconsistancies

Other than that, there should not be an issue with the retaining screws being a bit loose.

We had problems last year with a student who held the box in a vice while she worked on it and introduced a bow that caused the CIM motor not to mesh well when its screws were tightened. We wound up shimming the motor to reduce the gear engagement.

Since the topic of aluminum gears came up, we used VEXpro gears last year in what was a punishing game. We had no issues. That said, the VEXpro gears have the above mentioned spacers on BOTH sides of their gears and are therefore wider than the AM gears. We machined off one of the spacers and again we oriented the gears flat side to flat side.
