I suspect you are correct. I have been meaning to ask,  what to construct the 
main support colum out of. I do have a pourable ceramic material. Also in one 
of Tesla's older designs, and newer ones also, he had a metal core for the 
primary, the secondary was wound on non-conductive material. (in one eariler 
case, a wooden pole was suported by a metal pipe if the diagram is accurate.) 

 The oil actually keeps the coil cool by damping
molecular movement.

I recently read this, interesting how this works. 

I like this coil so much I'm going to wind another one.  This time I'll use
finer wire if I can get some.

Finer wire to produce more turns?
