I actually made a vaporizor using a ceramic bulb like that. Hooked it up to a rheostat. Hit pretty good, i still got it around here somewhere.
Colocowboy, I'm a sheetmetal worker now...although not really on the HVAC side, we have done it. We do more of industrial fabrication. We build tanks, handrail, guards, platforms, ladders etc. I actually went to an Apprenticeship National competition in Las Vegas a year ago. Out of the 80 boys that whipped ass back home, I placed 4th. It was a 3 day competition...Won a welder, a weeks stay in Vegas (Ceasars palace- me and ol lady), 800 dollars. Hell of a time!
