I was working on a self-built RC-Boat and the base material is XPS Polystyrol. It is a foam like syropor but very stronger. So it need to be cutted, but how?
For this materials you need to cut using the hot wire. It is a resistance wire which will be very hot by suppling with high power.
Using of a LiPo Battery anable you to be portable. I also give you high current, which is very neseccery by this application.
I think, the best way to tell you how you can do it is by showing you the pictures.
The making is realy not difficult. When you want to ask something, tell me by commenting.
I hope it help you. Best regards,

Reason for this BuildI needed a foam cutter to cut Polystyrol for a self-built boat. I did not want to pay a lot of money and could not find a portable cutter. That's why I built it myself.
