(No longer) quick rotary question..



>>>>>>>
Chip,

This is called "flaming" or "follow around" and is usually a sign of over 
coupling.  It just says "uncouple me or get rid of this gap".  One 
solution is to separate the electrodes a bit more.  A better one is to 
include a tappable series gap in series with the rotary.  You could lower 
the input voltage or uncouple the coil.  The cheesiest solution would be 
to back the electrodes off in your rotary.  The condition is a serious 
sign of faulty operation of a system.  Ideally, the rotary arcs sould be 
small, snow white pin points of light that are stable and don't oscillate 
about on the contacts.

Hope this helps a bit.

By uncoupling the coil, you do mean raising it a bit to take it somewhat
out of the primary's field, correct?  I also have a series gap that I can 
fix up a little to make it suitable for the higher power use.

The over coupling probably explains why my coil's performance isn't as
good as the best it was with the neons and air blast gap.

I'll try these things as soon as I make sure that my power cabinet won't
go flambe.
