I'd like to convert two of those left-arm parts into right-arm versions by relocating the tubes and "stop blocks" 180deg to the other side of 'Upper Arm B' and 'Lower Arm B'. Does this make sense? The other parts from the last project I THINK are okay (symmetrical) for using as right arm parts.
Perhaps it requires a bit more description and maybe a drawing from my end? Let me know. More parts to come also very soon. Project will become more interesting and challenging as we go.
