Re: [TCML] Strike rings - to use or not to use



That is an absolutely gorgeous looking coil.

I like the idea of using conductive UHMW - where do you find it? I'm stunned that the resistance is that low. Most carbon-impregnated plastics are fairly resistive.

Hi All,

Here is my design that I came up with in 2004. It uses 3/4" UHMW PE and has the primary machined into the the top. The black strike rail is conductive UHMW and measures 8 Ohms from end to end, and is grounded in the center of the rail. The acyrlic cover prevents things from falling into the primary, yet it is fully tapable from below. The secondary is a 4.5:1 aspect 6" of 24 ga wire with a 24" toroid.

I have only had the coil in operation for first light at Cheesehead 2004. On the trip home the secondary rubbed on something and damaged the secondary, and I've never rebuilt. I need to get sparking again!

Hi Kurt,

That's a very nice acrylic setup! I like how you've made the disc part of your support structure.

I also use an acrylic disc over my 4.5"diam. coils primary. It's not pretty like yours. I simply set it down on top of the runners. Seems like some of us are doing much of the same things these days.

Take care,
Bart
