Coil questions
Hello:
I am currently building a vacume tube Tesla coil and was refered here by
Richard Quick. Perhaps you could answer a couple of questions for me:
1.) Who makes #601 red insulating varnish, where can I pruchase it and are
there other/better ways to inuslate a coil once wrapped and lock down its
turns to keep them from vibrating and/or loosening durring use (which I
imagine is not a wonderful thing).
2.) Richard Quick (who seems to be very knowledgeable about these things)
seems to like the Noon computer program for calculating the basics of coil
design. He, and others, however, also say that the shape of the primary
[inverted conical helix, and flat pancake] and the resulting improved
coupling charactoristics and uniform excitation of the secondary will "blow
away other designs by producing bigger sparks with much less input power."
In using the Noon software, however, I noticed that the softwares'
calculated output voltage for any Tesla coil secondary is directly related to
(and only to) the input power (wattage) of the driving supply. This seems to
indicate to me that either Mr. Quick or Mr. Noon is incorrect. (I suspect
that Mr. Quick has the right idea). If this is so, how would one modify the
answer supplied by the Noon software so that it might more accurately
represent the output voltage of a properly coupled and uniformly driven coil
set? And by the way, what formula is the Noon software using to calculate
the output voltage of the Tesla coil secondary and what criteria is it based
upon (the standard conical helix primary?)?
