Warpping sheet metal

[tetramachine]

I am building a couple 1:12 scale Box cars. There is a trim piece the has a half dozen beads rolled into it.

After rollimg the beads in the piece is cut to 3 x 10. With all sort of twists. As a test I went over a test piece with a propane torch. It did not do much to flatten it out.

I have a heat treat oven which they would fit in, then. Heat and use a slow cooldown.

Thanks.

Perhaps a picture where 1000 words will not suffice?

Ahhh. WARPING! The title states "Wrapping."
Big difference and confusing.
