I'd like to cut some foam inserts for a gun case and I've been looking at building a hot wire cutter, but I'm not comfortable building a power supply from scratch, i.e. wiring up a transformer etc.
I was wondering if it's possible to use something like this http://www.mpja.com/prodinfo.asp?number=16854+PS and using a variable resistor on the DC output?
Any and all ideas are appreciated.
Ah, cool. I assume something like this would work as well. http://www.electronickits.com/kit/co...or/CKMX033.htm
Also while searching since last night I came upon this site http://hotwirefoamcutterinfo.com/Hot...y/Welcome.html and he has used a tattoo power supply to run the hot wire.
Thank you for the link, I think I have enough info I can get this under way.
I'm new to all this but I use an old pc power supply (12v wire) on my hot wire plastic bender...should work on a cutter too
