I once read a nylon fishing line could be wound on a secondary coil
along with an enamel coated copper wire. Give the finished coil 1
coat of polyurthane and let it dry. Unwind and remove the nylon
fishing line then give the coil another coat of polyurthane. There
is an optimum spacing for each wire size and coil design. The extra
spacing will increase the voltage rating of the secondary coil. I
think if you do so research and do the math you can probably
calculate the best Q of a given coil. Not sure how much noticable
improvement you will actually be able to see in the performance of
that coil. The extra voltage rating might be helpful in high power
coils and not so helpful in small low power coils.
