RE: [TCML] Sucker Gap

["Jim Mora" <wavetuner@xxxxxxxxx>]

Sorry Gary,

My bad, I was referring to the dual NST's. The leaf blower was on a separate
switch but its dial was up all the way for a clear "ripping" sound from the
gap and my best sparks - maybe something to do with hyperbaric pressure or
blowing clear of the hot ions? There is a lot more air variable at play in
the open like that. Anybody want to tackle the Bernoulli effects here ;-^)

Did you actually see a benefit to super-charging the leaf blower at 140VAC?
(!)  With my sucker gap, I found no improvement in performance above 24VAC
to the vacuum cleaner motor.  Certainly louder (from the screaming motor),
but no longer sparks.
