Ok I still would like input on all the questions!!  :)
But I woke up this morning with what I thought might be the answer to
part of my question.  Funny how the mind works stuff out while you are
asleep and it's the only thing on your mind when your eyes pop open.
Its kinda cool sometimes like being your own computer.  Throw in the
data, go to sleep, and poof an analisys comes out.  Ok never mind the
rambling, was just kinda cool to wake up that way again.

Is the major current in the primary of the TC due to in major part a
simple play with ohms law?  You have charged MC to a large voltage and
now are discharging it into a very small resistance the primary.  If
there is more at work id like to know what you all have to say,

Thank you very much for the replies on the toroid size question.  I will

have to digest more of that after I tackle a two fold question that was
brought up as a result of your replies.

Question 1:
I was planning on 36" arcs based on the formula I found somewhere
[]
where k is a value taken from a chart based on secondary dia.  in my
case
was .85.
1800 watts  (2 nst's 15KV 60mA ea. Totaling 1800 watts)

is this figure way off?
The formula given to me in the toroid replies was
spark length (inches) = 1.7*sqrt input power (wallplug watts)

Which is the correct formula to use for an approx.?
If I was going to drop to a single 15Kv 60Ma NST could I expect to
generate
3 foot arcs?

Question 2:
I would like to keep the discussion on cap selection limited to NST's
since
that's what I intend to use and to keep from getting too much info for
my
tiny little brain all at once.

I understand the idea of resonant rise in the nst.  Or at least enough
to
see what you mean.
The question is will the LTR cap (lower reactance) draw more current
from
my NST? Say a 15 60.
I was under the impression they were current limited and no more than
the
rated 60mA would be drawn.  Resonant rise plays a role in this?

Someone said that the current in the primary circuit can be in the
hundreds
of amps?  If so where in the -at-#$-at-#-at-~! Does it come from?

Ok maybe I opened a can of worms but id like to know what is happening
and
why the current can be so high and still not hurt the nst and where all
this high current comes from.

Thanx again
