I have several ways that I connect to a weatherstrip primary. Here is a
photo of my HUGE coil and connections to the primary.
It might not be clear, so here is a zoomed in photo.
That is what I call a big clip-lead. I make them up with 10 gauge speaker
wire (very flexible) and those flat-headed little clamps from the hardware
The clamps are soldered to the wire.
In case you haven't noticed, I use these to interconnect most of my coils.
I call it modular design. Hehe. My coils are always spread around as
parts/modules that I hook up as I see fit, using those big clip-leads.
Can't get myself to put it all into one box.
Sometimes I have hooked up from below the primary and had the wire hanging
I even use these clips to connect up to a pole pig, that I have run up to
60A at 240V.
Now I'm not saying that these are an ideal solution. In fact, the burn
marks I have on my primary are due to the less than perfect connections
sometimes made with these clip leads (sometimes I put polyethylene spacers
between the clip and the other primary turns). But I like the flexibility,
and don't mind a little extra excitement.
I did get 9 foot sparks at 7500 Watts with this setup. Some people thought
it was a good performance.
Still don't like it? How about this? This is what I used for my DRSSTC
The spring-bronze is solderable. If you get some copper or brass strips,
you can solder them to various tap points on the primary, and bolt wire onto
Anyway, this is what I have done. It should be enough to get you going.
