Oh... Well, there's nothing special about the primary wire either. The
connection to the caps is a fat red wire, with 1 or 2 mm of stranded wire in
the middle. The primary coil is around 22 gauge wire, nothing special. It
starts getting slightly warm after 20 seconds.

The topload, I mentioned, is the remainder of wire coming off the secondary.
It's roughly 6 inches long, wound around a 3/8" dowel rod as a form, coming
out to 7 or 8 turns. It seems to give the same results as the original copper
tube topload (1/2" pipe, ~2" diameter)

However, although people are telling me this thing is in fact in tune, I still
get absolutely no sparks exceeding 3 inches - ever. Do I need to connect the
bottom of the secondary to a spike hammered into the ground? Do I need to use
a "real" topload?
