First, be sure there is a "dot" between the ted and the rosenberg. People
over 40 <grin> need close up specs to see it I guess.
While there was some carbonizing (about 1/2 inch diameter)on the surface of
the Plexi, I can get rid of most of it and its in a place where it generally
won't be seen (below the primary plane and above the cabinet platform) which
is precisely why I didn't see it either when it was happening and the lights
are always dim in the room area. The moral is check and double check and
again...and use a flashlight if need be.
I will take extra caremaking the splice. Thanks for the confirmation.
And as for the variac...no, I did not use it for two reasons:
1. I felt that the coil was operating correctly at 120V...and it was OK
until the insulation melted through. In this case, it was a ticking time
2. when I want to scare the onlookers, I can't say "Wait...the small sparks
get bigger" as I turn the variac dial up to 120. I have to hit them with MAX
output in order to casue excessive screaming and a strong desire to
Technically I can see your suggestion for variac use and I will place it in
the circuit until I am sure that all is calm, and all is bright (in the

2. sand off the enamel on the end of the broken wire...about 1/2 inch. File
the #22 smooth.
3. Do the same for a new piece of wire.
4. Tin both. >>

Glad to learn that I did not miss the birth of your coil. Sorry about the
writing hiatus, we drove up to the North shore Chicago suburbs to visit
relatives. Had to wear shoes up there.
IMHO, a splice at the ground end of the coil will be of no consequence,
neatly done and well soldered. I hope you are using a variac with AC Amp
to fire-up this beast. Did the welding arcover damage the nice plexiglass?
