Hot wire foam cutter

[Ed Dawson]

Anybody have a hot wire foam cutter (or power supply for such) that I can borrow for a couple of days?

I made my own with a 12 v battery charger and some 30 guage nichrome. I’ve long lost the bow I had but if you want you are welcome to the battery charger and nicrhome element.

Thanks Edward.

Did you need to vary the voltage on the battery charger, or was it pretty much plug and play?And was it a car battery charger?

Perhaps I could cluge something together.

If mine does not work, I may take you up on the offer to borrow yours.

It is just a 12V sealed lead acid battery charger. I plug it in and hooked up to to the wire. I had to vary the wire to get it hot, then I just cut away.
