Inspectors please help! Protrusion from frame perimeter.

[stufflikethat]

I am working with a team that has bearings holding the the wheel shafts in the robot. The bearings are currently sticking out about an 1/8th of an inch past the frame perimeter. I don't believe this is a problem and should be legal due to 1/4 protrusions being "ignored" also our frame is a bit under 112.

The real questions lies in the bumpers. To make our bumpers work well we were planning on cutting 3/16ths deep slots about 1.5 inches up from the bottom of the bumpers so the bumpers hug the bearings. This will also allow the bumper to be right up against the frame instead of the 1/8th inch. Will the slots be a problem or are they legal?

Please correct me if I said anything that is wrong and will prevent passing inspection.
