03. Next, you want to do a quick run through on the English Wheel—a very simple and crude device that forces the metal between two dies to manipulate the metal. You can put concave, convex, or compound curves into metal with this simple wheeling device. You can also make metal perfectly flat with it. Understand that you are stretching the metal while you roll and it is becoming thinner and thinner the more you roll. It will also become denser. With this in mind, when you have a factory drawn (a manufacturing process of pulling steel over a die) piece, you want to make sure not to alter its dimensions. So go easy on the time in the wheel. The idea is to bring it back to original, not to a whole new shape!
