Chip,
Congrats on a lovely rotary break. Don't expect it to look so pretty
for long though, I expect the UV will start to fog the clear
plexyglass in time. You will also get some coating on the inside
from vaporized contact material mixing with breakdown products of the
internal atmosphere. It must be quiet. The majority of the sound
you would hear I suspect will be the whine off the streamer(s). That
is truly a 3-dimensional acoustical treat! I especially enjoy the
doppler effects of that sound outdoors as the streamer does its
intoxicating dance.
Nice streamer pictures. I'll be your friend Dave was impressed too!
Now you need a bigger garage!
regards,

[ The inside is already fogging. I believe that it must be due to the
electrodes corroding/vaporizing. Yes, the gap is pretty quiet. I
didn't go to any lengths to balance the thing, and it still runs very
smoothly with vibration only at a certain RPM (that's resonance for us
coilers) -- Chip]
