RE: toroid for my coil.

The 4x30 toroid will definitely work; you may just get multiple shorted
streamers rather than the longest possible single streamer.  Mostly a
personal preference thing.

I will be using a 15/60 NST a cap size of about .016 mfd and I have
finally
decided to go the static spark gap route for this coil and attack the
SRSG
later if I get the bug. (thanx everyone for the info there may be a
round 2)

I was going to use a toroid of 4" minor dia and about 18" major dai.
I happened to buy some flexible duct from McMaster carr and it is 4 1/8"

dia but the smallest I can roll this stuff is like a 30" outer dia.
would
this be out of the question for my toroid size?  I would still be at eh
4"
minor dia so the voltage breakout would be the same (I think)  but I am
a
bit confused as to how to figure out if there will be enough joules
produced to use a toroid of this size.  Seems there is no exact way of
figuring this out as a definite.  So thought I would ask the experienced

ones what they thought.

I like this ducting and really want to use it.  But if there is no way
it
will work with this coil ill have to figure something else out.
