Here's a pic of a hot-wire foam cutter I made from an old soldering gun I've had for about 25 years. It is 200watts. I took out and discarded the originag soldering tip. I used a piece of #10 copper wire to make two new tips. ONe is tunnel shaped and was used to cut the 18" raduiss tunnel through the foam block shown. The other tip is a long knife style. It can be bent into almost any configuration, as long as it doesn't touch itself anywhere. Cuts like a hot knife through butter. :thumb:
