Fabricating Stainless Steel Doorsills

[B] [A] The extra 3/16 inch needed to be formed 90 degrees using this machine. It’s an Erco former and flanger, which works like a leaf brake, with a brake plate tool (A) that oscillates in tracks in the frame, at as much as a 95-degree angle. I had a 3/8-inch 90-degree hold-down tool that I machined down to a 3/16-inch 90-degree hold-down tool (B), and used the 3/8-inch brake plate tool and adjusted the machine to maintain proper alignment to create the angle. After every pass, I slowly raised the brake plate tool two turns (approximately 0.060-inch) until a tight consistent 3/16-inch 90-degree bend was formed along the bottom of the sill, following the radius from front to back.
