Had a go at making a hot wire cutter to cut plastic and polystyrene. Experimented with 2 types of wire. Tried a thinner wire which worked at about 8 amps, but used a thicker wire in the end, as the thinner one broke. It draws about 16 Amps. Managed to cut the tops from some bottles with it. Will experiment a bit more and fine tune it. Want to try some expanded polystyrene. More pics here….
