Brett, Gerry,

Thanks for the suggestions. I took a bolt and temporarily placed it between
the two electrodes. Made about a 15% increase in number of streamers. I then
placed a 10" stainless steel bowel on top of the toroid. After some tuning I
managed to squeeze out about 10" streamers into the air.( Time to make
another gap and toroid) I made an observation that kind of puzzles me
though. On my other two Tesla Coils I can stretch the streamers out with a
grounded wire attached to a long pvc pipe. When this happens I only get one
bright, fat streamer. I could do this  with the small coil before the
modifications. Now the streamers can't be stretched much farther than they
extend into the air by themselves. When the streamer contacts the wire it
gets brighter but, won't stretch. I also have several more coming out from
all around the bowl. Seems like they are  not attracted to the ground wire
anymore. Any explanations for this?
