Standard aluminum tubing, welded, creates rigid attachment between hand cycle and wheelchair

Wheelchair and hand cycle after a long night in the metal shop.
Leaving the tubes free spinning allows for easier attachment by person using the wheelchair. Notice the weld ring on the attachment tube, this accident created a nice stopping mark, keeping the tube from sliding to far into the attachment tube on the wheelchair.
