Subject: Gap Cleaning
I cleaned my RQ gap a couple of days ago. I just slid some
sandpaper between the gaps and gave them a good rubbing. When I
fired up the coil Sunday night, I couldn't believe the difference.
My little 450VA coil was a crackling, hissing beast! The 8"
spherical discharge terminal sprouted many writhing, multi-branched
The 8" sphere normally requires a single thumbtack to produce a
reliable, single-spark breakout. After the gap cleaning, I noticed
that the spark from the thumbtack was very intense, and many faint
little streamers were coming off other parts of the ball. Puzzled, I
removed the tack altogether (which normally extinguishes my sparks).
To my amazement, the coil put on such a violent display that I was
intimidated to be closed up in my little one-car garage with it
If there's a point to this story I guess it's: keep your gaps
Or maybe: Minor tweaking can yield great improvement.
