I am a mad scratch builder and have been cutting foam board with a razor blade but would like to try building a hot wire cutter. I think it will be easer. Could some one draw me an diagram of the easiest way and cheapest way to make my own hot wire cutter. I have scrap wood 20 gauge steel wire I have extra push rods from FT kits I have a 3 cell 2200 mph battery and an esc and some screws laying around. Im 16 and don't have a job so I can't really buy anything else. Is that all I need or do I need something else? I appreciate your help. thank you.
