I could be wrong, but that would mean that the hole for the self-righting arm either isn't modeled in the far tube or isn't at the same height as the one on the near side. I'll wait for some clarification from s_forbes for a final answer.

I took the new circle on the plywood as a bolt to help transfer torque from the plywood to the arm.

Also, I'm not exactly sure what problem you are trying to solve, because I only (intentionally) raised one point in that last post.

I was referring to an arm which mounted onto both uprights, not just one. It would only take up an inch on either side; the would still go across the robot either outside the frame perimeter or above the main robot chassis. This was also in response to your concern about a cantilevered shaft.
