No Long Build + No Transformer = Great Hot Wire Foam Cutter

Intro: No Long Build + No Transformer = Great Hot Wire Foam Cutter

I needed a hot wire foam cutter, and fast, so I decided that instead of buy transformes, nichrome wire and all those things, as my material wasn't thick, I get some wire, (copper, but any metal wich conducts heat will do), shaped it, rolled it onto the soldering iron's tip and done!
A 5 minutes hot wire foam cutter (very good hot wire cutter) for free!
To help cutting I got a nail and a plank, used the nail to do a small hole, put the other wire's tip inside and It got much easier to use.

    Cool, how hot is your soldering iron?

    This is clever, I will certainly try it. Have you played with various lengths of wire to see how far out the heat will go and still work.

    I didn't needed to cut very thick plastic, so, I didn't tried a longer wire. However as copper conducts heat very well and the soldering iron Is very hot, It should hold a much longer wire.
