FW: Damage to the Secondary


I know the feeling.   When I moved, my 12"x60" secondary fell out of the
back of the wagon and went down the highway end over end.   I almost had a
heart attack.   It got a dozen turns scraped off one end.   I have not yet
run it again to see if it will be a problem.   I have recoated it with

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.

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?
