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

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
