Re: Never Do This, and Other Good Ideas Gone Bad

Don't use rigid couplings or pin shafts. Love joy 3 piece couples are great as are offset couplings.

The benefit is 2 fold, it gives you some wiggle room in case things aren't perfectly lined up (like that would ever happen on a FRC robot) and it also makes changing parts much quicker in the event of a failure, you can build spares right up to the coupling.

my $.02

On my teams I will not allow scissor lifts, mecanums, multi stage elevator lifts, winches, large pneumatics or belt type conveyors (poly cord ftw!)
