I saw a very slick set up the other day.
The guy cut and polished 2 sections of PVC pipe the width of the retaining pins with less than 90 degree arcs. The pipe segments were drilled and attached to the unit with the pins and partially wrapped the wrist. The PVC pipe segments were also drilled to receive bungee which went around the wrist.
Don't know if I explained it well enough.
I think I get it... but maybe a crude picture? That must have been some very very thin pvc pipe!
