Mitch, Sorry I can't help out with a source, but I can offer some health tips:
> through the smokebox. I've seen > Teflon and silicon insulated wire advertised as high temperature tolerant. You should not expose any thing made of Teflon to direct flame. It produces a poisonus gas that will make you very unhappy. Through the smokebox would be about the worst place imaginable to have Teflon. I'd suggest running it through some brass tubing -- just big enough to get the wire through -- and along the boiler jacket. This is prototypical and keeps the Teflon and fire away from each other. regards, -vance- Vance Bass Albuquerque, New Mexico, USA Small-scale live steam resources: http://www.nmia.com/~vrbass
