Quoting RussellMc : > If you used Nichrome and brought the ends out to a cooler location > you'd not have the problems that Bob mentions. Was trying to tweak what I have already, and not redesign/rebuild =20 (which I don't have the time for right now). Since what I have is =20 already/mostly done, and I have no other purpose for those parts, at =20 this point I will probably just try to overdrive it a bit, and if it =20 fails I'll prob just buy an existing extruder head kit.
