Yes. The additional insulation can be helpful on larger, higher powered
coils so that they can better withstand higher volts/turn stress or
mechanical damage via moving/handling. The greater thickness of
insulation means that you'll get fewer turns/inch (it's sort of like
using a space-wound coil), and significantly lower inductance for the
same winding length. Again, for larger coils (with larger coilform
diameters) this is not a problem and is often desirable.

Thinner insulation allows closer turn-turn spacing, allowing you to
maximize inductance for a given winding length.

Check the archives at http://www.velocity-dot-net/~djb/files.shtml and check
out crazycap.gif, cap.txt, capacitr.txt, and capinfo.txt.

No problem! Unfortunately, I know of no single book that pulls it all
together (as yet). Books/booklets that do exist reflect current coiling
knowledge/wisdom at the time they were written, or reflect more generic
electrical engineering topics not specific to Tesla coiling. 

Also, there have recently been significant strides made in
understanding, simulating, and experimentally verifying the operation of
various portions of these systems by a number of people on this list.
For example, Terry Fritz has developed certain remote high voltage and
current measurement techniques, and has compared experimental versus
predicted results from simulation models. His very well-written articles
delve into the theory and operation of various elements in the system.
Check out some his work at

Finally, if you still have questions, ask the members on this list! 

Safe coiling to you!
