In this installment I show you a hot wire foam cutter I built. Styrofoam can be used for tons of projects, not just for insulation. From building theatrical set props to surfboards, windmill blades, and aircraft, this versatile material is at the core of making all of them. I show you how the hot wire foam cutter is built, how to control the temperature settings, how it's set up, and how it's used. This tool can be built in an afternoon with easy to source materials, such as threaded hooks, chain, stainless steel wire, a 2 x 4, and a 12 volt battery charger or 12 volt auto battery. After the setup, I show you one example of what can be made out of foam, and give a lot of details on how to set it up properly. I also show how to make a template out of plywood, and how to cut a model airplane wing section airfoil from a piece of foam using that template.

DO NOT ATTEMPT TO CUT POLYURETHANE FOAM WITH A HOT WIRE CUTTER. IT IS ACUTELY TOXIC. Only use on polystyrene (styrofoam). Even then, avoid breathing the fumes.
