Hey, 
would it be crazy to do two rotary spark gaps?  I mean, since I already have a
6" bench grinder with two rotating axles, can i use them both?  Or should i
only use one?  Also, does anyone have plans for a suction/blast gap that isnt a
richard quick style gap?  I just fired my tesla coil up for the first time
today, getting about 18" streamers in all directions, 22" to a grounded copper
tube, and all I am using is a simple two-bolts-spark-gap.  I am very surprised
this coil even worked, its on black pvc! 
Thanks, 
Dan
