Here is the very simple straightening jig that I came up with in the wee hours of the morning. The first picture (front view) shows how the vise is mounted to the workbench. I had to cut out a relief in the front support of the bench to mount the vise. I bought the vise at Home Depot for around $15. The second picture (top view) shows how I put a strip into the vise and then use the simple wedge to apply pressure to remove kinks and bends. If the kink or bend is going the other direction I just place the strip in the vise with the pith side facing up. This simple jig allows me to leave the strip in place until fully cooled, an otherwise somewhat arduous task if held by hand. I can then proceed to heat up another strip while waiting for the current strip to cool.
