HAL:

Notice how the sparks are emitting at 45 to 50 degrees from the 
horizontal plane?

This indicates your spinner is not sufficiently elevated above the 
electrostatic protection plane of the toroid.  The toroid is 
partially shielding the spinner and causing the sparks to emit 
slightly upward from the sharp edges on the spinner.

If you elevate the spinner with a longer brass rod, perhaps another 
18-20 inches higher, the sparks will emit in a near horizontal 
plane.  This will produce more thrust and hence greater torque, which 
should result in your spinner achieving high velocity.  As you 
experiment with elevations the goal is to have nearly horizontal 
streamer emissions.  This produces maximum rotational torque on the 
spinner and usually highest possible velocity.

Interesting design.  Good luck with your nice looking coil.
