As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.
Bending 22 gauge hardened steel sheet.
Next place the wood parallel and slightly behind the bending line.
Step 2 slide the angle iron into the jaws of the vise so that it lays flat the length of the piece of metal you are going to bend.
Finally bend the sheet up by hand to the angle desired.
Keep in mind that some metals are more brittle than others.
In this video i ll show you how i made a simple jig that allows me to easily bend plate steel and sheet met.

If you want a sharp 90 bend tap along the crease with a mallet.
Mark a bend line and place the sheet metal on the edge of your bench.
22 gauge 0 030 0 76 mm 0 5 12 7mm.
22 gauge 0 030 0 76 mm.
