The particulars are on one of our earlier videos.  I can't remember all 
the details.  The coil went in the dumpster years ago now.  I do remember 
I wound it on 1" PVC 8" long and then placed it in a 1-3/4" i.d. clear 
acrylic tube and filled with mineral oil. I did buy a formal spun 4" 
toroid for the thing though.  The rest is just the usual tesla coil stuff 
from there.  

To us, all coils are transient and the only reason we build 'em is to run 
'em, learn what we need, destroy them, and build the next, only to see it 
destroyed, etc.  There is no such thing as a sacred coil.  If there were, 
we would be knee deep in the damned things!  I have to go back to my own 
videos to figure out what I did sometimes.  We have wound a bunch of 'em.
