Glenn,
Regardless of whether you had the base of the free coil grounded or not,
it will resonate at its characterisitc wavelegth as a 1/4, 1/2, and or
3/4 wavelengths.
Where the 6" coil's spark hit was a nodal point on the 4" where a high
voltage appeared out of phase with the 6" coil's arc. The two added
together and a nice long arc which stayed connected was the result. The
arcs found one another at the ideal summing point for the two systems.
