On another note, I've trashed 5 sets of coils so far, first set were contact, all the rest have been spaced. I'm putting all 40 watts to them and barely hitting 300deg according to the DNA. Last pair I made were on a 4mm fine threaded bolt, winds up with an inside diameter of a little more than 3mm, 10 wraps, came out to like .24...I took one back out and ran in single coil, and finally got to 320 deg temp set at 24ish watts, but it started tasting bad and getting too hot for me. Gonna scrap all of it up til now and try again later today going back to contact coils. 10 spaced in a CEO Fog is too much. I also haven't been dry firing new wire. Going to try that too, just enough to make it glow a little n make sure there's no hotspots. Messing around last night with it I dry fired the first set of spaced coils at 40w, my atty turned into a lightbulb, wire cooled off and it had yellow flakes on it, and it lost ALL springyness and turned into a cracker lol. I kind of figured it'd pop, but oh well, it was neat to see
