Foam Cutting
Cutting foam cleanly is central to building wings and fuselage cores from foam blocks, and the usual method is a hot wire that melts a smooth path through the material rather than tearing it. This category supplies the core pieces needed to put a hot-wire cutter together.
Power Supply and Wire
The foam cutting power supply provides the low-voltage current that heats the wire, while the Ni-Chrome wire is the element that does the actual cutting. Ni-Chrome is chosen because it heats evenly and holds up to repeated use as it is tensioned across a bow or frame.
With a steady heat source and the right wire, a builder can slice accurate airfoil shapes using templates, which is how many foam wings are shaped at home. Getting the heat and feed rate right takes a little practice but produces a very clean cut.
