CNC Hotwire Attachment

That's a completely different application, but if I was still into RC, I'd have to consider it.

I came across this site for calculating the requirements for any given gauge and length of nichrome wire.

Pretty easy to use. My wire is about 0.008" diameter and 12" from contact to contact. For a temperature of 480F, I'll need 0.747 A at 8 volts. Kind of hard to get an accurate voltage out of a transformer run from a dimmer.

If you can't get one, make one.
