Not the intended response and I am already satisfied with my anser now
so no need to reply with an answer.

But I did want to say your idea does sound cool.  Although I am not up
to the project.  But if this were to get someone to make such an animal
id like to hear about it.

this is an interesting topic.
there are examples of pancake coils out there. it looks to me like it
would
be a fascinating experiment
to wind a 1500 turn coil that's only 1" tall and 10" across, the hole
thing
could be cast in epoxy.
the pri coil could be below or around it also cast in the epoxy.
I like the idea of alternative coil designs. I think it would be fun to
make a small coil with super insulation and over power it to the max and

see if you could get your 50" sparks out of a 10" disk.

read you later
