Grill air intake opening support insert development.
Picking up grill height shape.
The inside line is the line transferred from the duplicator as the bend line and the flange width line laid out from there.
Picking up grill width shape.
Transferring width shape to blank.
Hand bend radius to fit grill opening.
Tipping dies in bead roller used to bend flange on the curved lines with 4 or 5 passes.
The flange around the tight bend requires stretching and with 6061-T6 aluminum it was almost to much. The first 2 split. The last one was annealed and made it but if I had to do it over I would use a different alloy for this part.
Good fit that adds strength to the top of grill and supports the shape.
