I was showing one of our mentors the workings of one of our Toughboxes when he noticed the incredible amount of slop in the gearboxes. He suggested shimming them. We used a 7 mil brass shim on one gearbox, but, strangely enough, the other gearbox wouldn't even fit 4 mil.

This is frustrating because the tolerances on other parts were very tight (e.g., getting the bearing over the output shaft, inserting the roll pin).
