One of the reasons for taking classes at the Columbus Idea Foundry is to learn how to use the equipment safely. It’s common for the instructor to choose a simple project for the students to build. For the sheet metal class, the project was a hinged box. We started with a medium-sized sheet of aluminum and a strip of piano hinge. The tools we used were the foot-powered shear, the corner shear, the drill press, the vertical bandsaw, the finger brake, the Milwaukee horizontal bandsaw (to cut the piano hinge), and a hand-held pop rivet gun to fasten it all together.
