Being new here I do not know if this has been discused before. But I needed to cut styrofoam and hate the mess that it makes. Being cheap and not wanting to buy an electric one that melts it's way through I decided to try to make one. I used an old weller soldering gun and replaced the tip with a piece of number 12 bare copper wire and it worked quite well. I also tried to make a bigger hoop with number 14 wire. Both worked just fine but you are limited to the size of the hoop as one to big will not heat enough to burn the styrofaom.
Hope everyone is having the best day that they can.
