Hey Bart,
Your neighbors are brave, I ran my coil on Halloween night
downtown at my cousins house, I only had three people ask me anything
about it the whole night, running it in public for about 4 hours (on
and off of course, short 1-minute runs as people walked by on the
safety of the sidewalk) in front of just about every person who passed
by. I guess the people of Berwick Pa don't care about 5 foot
lightning bolts...

Hi All,
Yesterday, I went after cleaning up in the garage. My little 4.5"D coil
was full of dust and debris, so I cleaned it off. I decided to put some
of the pieces back together (NST was out). Anyway, after the cleanup and
remounting the NST, I decided to give it a little test run. Nothing!
Hmm... I remember I had a problem with the Terry Filter that I had yet
to dig into. So, I unhooked the Terry filter and gave the coil another
go. ZOOM!! Lot's of great sparks in the 5 foot range.
Unfortunately, I had my garage open. A couple guys working on a house
across the street showed up. After answering all their questions, I
decided to run it again for them. Well, you know how that goes. Ran it
for too long and too high of power. It ran great, they were thrilled.
But, it all ended right when I decided to shut it down (hand on the
variac just starting to turn it down). I didn't think much of it, but
today I decided to check it. The NST is dead for the 3rd time. Looks
like I'll be melting the wax out (it's filled with wax, so actually an
easy process at this point).
The Terry filter also includes the safety gap and I ran without it (took
a risk and got bit). With the Terry filter, I've ran this coil
non-stopped for 30 minutes without failure at 1.2KW with a static gap.
This time without the filter, it lasted only 3 minutes.
So, don't forget the Terry filter!
Just a reminder.
Bart
