At first we had somewhat of the vibration issue since it was slightly unstable by itself, then we added a pillar block on the other side (with a free shaft) but it made a lot of resistence from not being perfectly in line. So we slighty drilled the holes wider and mounted them nicely alligned. Oh, and make sure you use plenty of lube on any freespinning part.

The main supports are 3/4" steel (square, hollow, from Lowe's) while the extra supports are 1/2".

It was the first day shooting it while mounted on the robot but at least 85% of the shots on full power landed within the same cement square.

The Banebots are 550s with 4:1 gear ratios, and they use the grey rubber wheels.
