Hey Jim...

I have a primary coil already made and sitting in the shop but since 
the hurricane I have stopped working on the unit. If you are 
interested in it we can talk a bit more via email....   since you are 
aiming for 6KV this primary may be of use to you...  I dont remember 
the exact dimentions    but if you are somewhat interested I will 
make measurements of it and tell you more about it ( could even send 
pictures of it too)....    if you are really interested in the system 
that I had started, I have some Chenelac caps ( supposed to be really 
great caps) and a rotary spark gap available for a price to be haggled over....
