could hot glue be used to secure each baffle inside the pipe? I have 
a ton of plastic hot glue rods, is silicon a better alternative?

Thanks,

2 to 3X sec coil length is producing a tremendous amount of stress on
a coil.  Good HV engineering would require some prudence in initial
design especially if an experimenter is doing it from scratch.  My
intent was to intice him to use baffles to prevent problems.

I know sometimes one can get away with up to 2 X coil length spark
discharges, but it's pushing common sense to not use baffles.  As I
said, the time spent repairing the coil could be saved by spending an
extra 15 minutes installing baffles when the coil is initially constructed.

I actually had a friend who drove a 65 Mustang 289 engine for over
90,000 miles and never changed the oil once.  He always said, "Hey
--- it' still running!"   I just shook my head and smiled --- and
wished him well on long trips after dark.  I never did see him walking!
