James,

That is a good idea indeed. Thank you.

- And I wound the grid coil onto a ring 1/2" wide, which I cut from a  
8" coupling piece. Between the ring and the 8" form I placed some 
small plastic parts which hold the ring in place but would allow 
easy shifting for tweaking. Got the idea?

- Here the inner plastic insulation is nearly 1/2" thick and I got arcs 
for all that.

- This is a very impressing system, James. I am very surprised that 
you got so long arcs out of a single MOT. Congratulations!
