I tapped the primary at 10 turns (instead of 6.75) and got these wave forms:

I expanded them and got this for the primary current:

I got this for the secondary current:

I then raised the secondary 1.75 inches with the nice standoffs Marc sent me with the coil tapped back at 6.75 turns again:

And I got these primary and secondary current waveforms:

I expanded them and got this for the primary current:

http://hot-streamer.com/temp/TerryCW/2001-5-28/CSVFFT02.gif

I got this for the secondary base current:
