No, I think you're right and we're saying the same thing. Now I'm really reaching here back to high school physics, but if I recall correctly, it takes about 20,000 volts to jump 1 centimeter. Can someone confirm or refute that? In any case, if it takes more volts to jump a longer distance, a larger gap would mean higher voltage before the spark would get across, and a smaller gap would mean lower voltage to get across. I think that means smaller gap=quicker spark=lower voltage=cooler fire and larger gap=slower spark=higher voltage=hotter fire. Am I missing something here? tx, bmc :) Ben McCafferty ben@volkscafe.com Volks Cafe 1823 Soquel Avenue Santa Cruz, CA 95062 831-426-1244 http://volkscafe.com
