 Reinhard:

I agree that don't want to heat the walls of my house with the wiring, but
why waste all those perfectly good electrons heating a pot of oil?-)
Obviously, if it works it works, but I'd still wind it with the biggest
wire I could (within reason). Bigger should do no harm, except possibly to
your wallet..and I'd rather not have to do it all over if the first try
went up in smoke.

still scrounging for parts (and time) in Chicagoland  to build a bigger
coil
