Hotwire cutters are useful for cutting all sorts of materials. Although they are not too tricky to make there can take a bit of guesswork to build something portable and easy to construct. This super simple wire cutter just uses an old computer power supply (or laptop supply) and tension from a PLA/ABS bow to keep the wire tight. No springs or funky tension systems are required just cut your nichrome to length.
An inexpensive speed controller allows you to get the temperature perfect and the rest can be easily found around your shed. I made mine from scraps!

Nice work, Been getting back to n-scale model railroads. It ends up that a foam cutter would be a nice to have next go around. I like that it has a good mix of materials and uses a older computer power supply you may have laying around.
