Cat5 Bumper Mounts

I don't have experience with this, and as much as I like to see rookies "descend" on the robot, I hate to see members struggle to mount bumpers as we are walking to queue.

The nesting of the kit channel clip over the 1' square tube takes care of the vertical movement (haven't measured the exact clearance, but it's pretty close) and the ball lock pin takes care of the horizontal plane. If you drill a 1/4" hole through the square tube, the clearance is just that of the 1/4 inch ball lock pin and the 0.257" hole in the kit channel. Connecting 2 bumper backings together at a 90 degree angle (with wood screws and/or glue) makes any wiggle almost negligible. The issue we saw with wingnuts our rookie year is that not every student can get them really tight, and some loosening was possible during the match.
