Shop and Jigs

This is my rendition of the Wolverine arm. I don't have welding skills. equipment (it's on my list) or machining tools, so I have to come up with other solutions. I used shelf standards for the arms, housed them in plywood and made the cups out of hardwood (forstner bits drilled the holes at an angle). There is a leaf of sheet metal under the thumb screw that pushes down on the arm when the screw is tightened (T-nut under the ply)
