I hope it helped.

There is a difference between good performance and excellent
performance. Nine times out of ten, good solid performance is
quite acceptable.

See the post coming up in Chip's group about the "SEAGATE QUENCH
GAP". This sounds like the most practical approach I have seen in
many months.

Don't use the quench gap. Quench gaps are highly application
specific and will not provide the best spark on many 1/4 wave
systems. Quench gaps are used where there is no light or noise
permitted from gap system (stage coil for instance). They are
probably the best gaps to use on wireless power/transmitter
systems because the tank circuit rings for a long time resulting
in a smoother wave train.

In a spark producing 1/4 wave coil, like most of us are building/
firing, you want a sharper switching gap system. In my experience 
the beginning neon coiler is best off with a simple cylinder
static gap. They are pretty quiet, don't produce a lot of glaring
arc light, and have considerable room for customizing with
baffled ducting for instance to further decrease the noise factor
and remove toxic arc gasses at the same time.
