I agree that in the pic in post 15 it looks to be going through the tube, but in the latest image on the far side there is a hole in the plywood not through the tube. On the other side of the hole there is something metal with a round bore in it, which I assumed was the bearing for the self-righting arm. 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.

What exactly do you mean by "U shafts"? I'm not sure what you are referring to and I am having a hard time picturing how anything U shaped (or not U shaped for that matter) could connect to both arms without having to cross through the center of the robot, which I am assuming was intentionally left open to leave room for a manipulator otherwise there is no room to mount one. Also, I'm not exactly sure what problem you are trying to solve, because I only (intentionally) raised one point in that last post.
