Jim,
It is never a bother to answer questions on this list. That is what it is
all about. You can make small coils run using the 5kV and 7.5kV NST's, but
they won't power one as large as your 8 inch pvc. I would suggest winding a
coil on the 4 inch form, using about 1000 turns or limiting the length of the
windings to about 20 inches(depending on the wire gauge). The most likely
choice of wire gauge to use would be 24AWG for your first coil. The 7.5kV
neon should get you an output of about 10 - 12 inch streamers as a guess.
Hope this helps.
Mike
