I'm finally ready to tackle the rust repair on the bottom of the doors of my 1937 Buick. Like most panels, there are no aftermarket parts, so I need to fabricate. The shape has a large radius leading into a .875" radius near the bottom that leads into a sharp corner and vertical tab (return). The part is further complicated by the gradual curve of the door from front to back.
1) Does anyone have suggestions as to equipment, or process to fabricate this shape?
2) The ends of the doors appear to have a folded over hem that captures the sides. Has anyone fabricated this section and can you show me how it was accomplished?
