Re: Tesla coil on Ebay; 80-300' lightning?

Not very well. Larger secondary diameters are needed. Given turn requirements to meet inductance's needed, 8" is too small to be practical. You would end up trying to wind a 6.5" diameter coil and it would have to be helical adding to the difficulty with coupling, placement, and mechanical winding. Either external or internal is electrically/magnetically equivalent, but practicality is best external with that small of a coil. 

Take care,

Hmmm, would a internal pri work with a smaller coil , say 8" dia. ????
