A hot wire foam cutter is a must for anyone who is serious about modeling with foam. Foam is an extremely useful and versatile material when it comes to model making but to truly get the most out of it you need the right tools.
Building your own hot wire foam cutter is very easy and once you know how they work you can build all types of different foam cutters for an infinite range of jobs.
The foam cutter I’m making today is a tabletop precision foam cutter used for making very precise straight cuts. Additionally by incorporating the temperature controller into the wiring I now have complete control over how hot the wire is.
Controlling the wire temperature is vital for getting the perfect cut, too hot and the foam will melt before it even touches the wire… too cold and the wire will start to flex giving imprecise angles!
