Rod,
I too have considered this idea (blast air through hollow electrode),
but
haven't tested it. I suspect that in many Tesla coils, the gap may
quench
BEFORE the spinning and fixed electrodes fully line up. The electrodes
may
get a chance to overlap only slightly before quenching occurs. The
result
may be that the air that is blasting through the center hole may never
get a
chance to contribute to the quenching; the spark will already be
quenched
before the spinning electrode comes into the path of the air. It may be
possible to drill the electrode center hole at an angle so that the air
exits
very close to the edge of the electrode -- this may help.
I have a theory, that in tightly coupled systems, such as a magnifier or
"tight k" classic coil, that it may be impossible to quench on the first
notch just by adding air; the amount of air that is needed, may stop the
gap
from firing at all. If air pressure is reduced to allow firing to
occur,
than the quench may again become sub-optimal. This is speculation on my
part. Perhaps someone will do the needed experiments.
