Here's some of the forming process of our A-Pillar fabrication that I missed the other day. Did a couple time lapse videos, first shows the shrinking of the corner. The Vise Grip tucking tool, torch, and hammer is used to get the corner to come down about a 20* angle, then the two flanges were folded, which gives us one big tuck. At that point wide VEE is heated up and the high spots of the flange corner is hammered back into itself. Repeat for the next high spot, until the corner is folded where you want it.

Here's the corner shrink complete...
Then the barrel end hammer is used to make the joggle creases by using an upper die from our press brake as a post dolly. That’s the basic process.

If you find the time lapse too fast, you can change playback speed on YouTube to slow things down a bit..
