Bert,

I wasn't trying to imply that you were over K'd with the conical 
primary, just that at the top voltages you are going to see with this 
spectacular coil you could probably use some extra room to ground 
which would be provided by a flat spiral primary.

I didn't know that you were using the actual legendary Nemesis primary. 
If I had I would _never_ have suggested running a steamroller over 
it!   I hope Richard Hull will forgive me.  : )

Have fun!
