Hi John...

an afterthought just occured...

to reduce the over all size of the primary ....

run the first several turns ( inside ones) either helical or at a steep
angled conical and the rest
at the flat pattern

see HTTP://members.telocity-dot-com/~bigfoo39/

and look at the design under Tesla Coiling, pictures of the BIGPIG coil
