Nope. All of the good stuff, with the exception of one spark gap
project, was archived. I started keeping records about the time
interest my FIDO postings was taking off, and I stopped when
interest fell off. Now I post here of course. You should have
just about everything.

Well, my wire charts show that number #21 AWG copper magnet wire
has a diameter of about .0285 inches. = about .7239 inches, so
the size sounds ideal. If the coil form, and completed coil, are
both properly sealed and you fire with the proper discharger I
see no reason why it should not work fine. On bare wire coils the
double Formvar coated wire has visibly less corona losses.
