 If you connected the inner turn of one coil to the outer turn of the other, 
you
 increased the self capacitance greatly.   How much, I don't know, but I seem 
to
 remember that a bifilar would helical coil has about four time the self
 capacitance as a single wire coil of the same dimension.

I think i recall reading, coil capacitance increases geometrically with size. 
A twelve inch coil would be several times the capacitance of a six inch coil. 
 i (dimly) remember that a 24 inch coil was discussed in Martain's book 
detailing some of Tesla's patents.
