Mike -

I used a metal stretcher - do NOT bend it at 90 degrees - I bent mine to about the angle I wanted - something a little flatter than stock.

You have to then use the stretcher on both planes about the same amount as the "curve" is vertical and horizontal.

Anneal first and get a few extra sheets cut and bent so you can practice first (if you are new to this).
