      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 numbers are the items numbers from the parts list**

    Reason for this Build

    I 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.
