Mark a bend line and place the sheet metal on the edge of your bench. Keep in mind that some metals are more brittle than others.

Grab the top of the metal with the pliers as the section you heated cools off and pull towards you gently at first. You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. If you want a sharp 90 bend tap along the crease with a mallet. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Next place the wood parallel and slightly behind the bending line. Category thickness minimum bend bend radius. 22 gauge 0 030 0 76 mm 0 5 12 7mm. If you need to reheat the metal and redo the bend.

Clamp the wood on top of the metal to the workbench. The metal should bend but only bend it as far as it goes without forcing it. Simple sheet metal bender using a hand roller clamps and plywood.
