I have a new 6"x28" secondary, where one turn was slightly loose and
ever-so-slightly higher than the rest of the turns.  I noticed that when the
coupling is just marginally too high, that raised turn is where racing
sparks want to start.

			I wound a 4"x22" secondary the other day with 26
gauge wire, and started
		coating it with polyurenane.  At some time during this long
process, the
		form fell over and screwed up a big chunk of wire.  (It
landed on a sharp
		car-jack edge.)  None of the wire was severed or anything,
but it was
		pushed up and squished. About a half an inch of wire was
ruined about in
		the middle of the secondary.  Now after I threw a fit, I
went and wound
		another one.  Since I have access to a mechanical lathe that
totally
		automates the process, I can wind an entire 4x22" coil in
under 10 minutes.
		:)  (That oughtta' get some envy from fellow coilers who
have to do it with
		a crank jig or even by hand. :)   So anyway,  my question
was,  just out of
		curiosity, what would happen exactly if I purposely used the
damaged coil
		in my Tesla coil system?
