Start with 3/4" stock about 2' long. Drill a 5/16" hole centered 5/16" from the end. This will leave you .160" from the tip to the edge of the drilled hole. Insert and center a 5/16" X 1.5" pin. I've attached 3 photos so you can see where to make your bends. I hope this helps. Attached Images Last edited by SSG26K; 01/20/24 10:12 PM.
