How to make homemade adjustable, self-tensioning electric Hot Wire polystyrene Foam cutter for lost foam casting, model making, cosplay, etc.
Cutting polystyrene foam is easy with a hot wire cutter. But the wire sags when it gets hot and it’s hard to get accurate, straight and nicely jointed edges.

Now hot wire foam cutters very popular on YouTube. It's a well covered topic and you SHOULD look at several videos to get a thorough understanding. However I've decided to share my ideas on how to make an adjustable, self-tensioning, accurate and reliable hot-wire foam cutter.

It's a simple build with basic tools that costs a fraction of cost of a store built cutter, and those you can't adjust!
