I am also very curious as to winding a second layer over the first.  The
length of wire of the outer layer would be slightly longer than the
first,
but then again, at the frequencies we are working with, the phase
difference, i.e., voltage difference between adjacent turns would be
negligible.  Has anyone tried this?  I'm interested because I'm thinking
about doing this very thing on a magnifier secondary driver coil.

In desperation, Bert hastily built a Tesla coil out of parts torn from a
toaster, a microwave oven, and his wife's hair dryer. . .
