When working with sheet metal one particularly useful piece of equipment is the brake. A brake is a device that allows you to bend a piece of sheet metal at a particular angle. Metal shops have brakes mounted at different angles with automated braking arms, however it is possible to bend sheet metal at home without the use of a brake.
Things You Will Need
-
Determine the angle at which you want to brake the metal and mark it on the protractor. You will use the protractor to gauge the brake as you bend the metal little by little. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges.
-
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.
-
Sandwich the sheet metal into the jaws of the vise as well. As you bend it the metal will be heading towards you.
-
Light the butane torch and use it to warm the metal along the section where you visualize the bend to take place. Get the metal glowing red to orange, but not white.
-
Grab the top of the metal with the pliers as the section you heated cools off and pull towards you gently at first. The metal should bend, but only bend it as far as it goes without forcing it. If you need to, reheat the metal and redo the bend.
The Drip Cap
- Working with sheet metal can be a rewarding, albeit sometimes frustrating, experience.
- If you are a part time or "recreational" metal worker, you may not have access to all of the workings of a metal shop.
