Fabricating Stainless Steel Doorsills

[A] [B] To create the countersunk mounting holes, I used the lathe to machine a male (A) and a female (B) die for the Pullmax, which were aligned with an 1/8-inch pin in the upper (male) die. I made a few test stampings with the dies before welding them to the shafts. I used test pieces of aluminum and stamped it in a vise to check for proper material clearance, and fine-tuned until there were no tool marks and the screw bead detail accurately matched the originals.
