Folks-
Recently there was a short thread about different types of connectors to
tap the primary coil. Well, I finally got around to taking a coupla pics of
my primary tap connector:

Very simple. I just took a small aluminum block, drilled it through for
the wire, drilled and tapped for setscrews to hold the wire, drilled a hole
for the primary coil's tubing (helps to drill from both sides at an angle to
match the curve of the primary near the tap point, but not necessary), and
drilled crosswise for the clamp bolt. I then sawed the block in two halves.
Tapped the wire side for the clamp bolt, counter-bored the other half for the
head of the clamp bolt so it wouldn't protrude. Rounded off all edges and
corners.
The set screws for the wire and the socket head cap screw for the clamp
are stainless steel. I was hoping that they would be ozone resistant, and
their higher resistance would mitigate inductive heating. Just make sure you use
anti-seize on the threads, since otherwise stainless and aluminum can get
quite sticky - and there's a lot of current pulsing through the thing...
