We've been thinking about repairing a wood robot chassis if it has problems where the wheels mount, or where bearings enter it. I think you could probably make a resonable repair with thin sheet metal on the outside to restore a bearing hole, or slightly thicker metal (perhaps 1/8" x 2" steel strap) to repair a broken area where a cantilevered dead axle mounts. Or you could mount dead axle on a piece of metal that extends below the robot, and is screwed to the outside of the frame rail.
