The square 4x3 inch aluminum tube has arrived and I've already started measureing
I've been worried about my A&A Foot Motor Holders not being able to hold R2 when he makes a turn, So this is going to change.
The tubing has a 1/8 inch wall and I plan to only cut away what is needed.
I will also add some additional bracing inside the tube.
I need to stop at the shop and pick up some aluminum bathroom partition mounts to make the channel where the ankle fits.
More to come.
