Hi Everyone!

	I just ran my coil, and for the first time was able to get some
meaningful information about it.  For the first time it ran perfectly
(no caps blowing up, or secondary breakdown).  Anyway, I've been
noticing that the first spark the coil spits out is always the longest. 
I tried varying the speed of the vacuum blower on my gap, and found that
the coil runs best when the blower is wide open at the full 240 volts.

	Could I benefit from a rotary gap?  Building one would be tough, but I
have several motors that could be modified to make a SRSG.  I could also
modify one of my vacuum blowers (they run at 20,000-30,000 RPM) for an
ARSG.  Has anyone tried to use a Dremel rotary tool as an ARSG sparkgap
motor?

	Also, could my metalized polypropylene caps be reducing spark output by
much?  I know they are not very good for TC use, but after tripling the
runtime on my coil from 5 minutes to 15 minutes I haven't lost another
cap yet :-).

	Will polyester film caps work in an MMC?  If so, how well?

Thanks,

Winston
