As a matter of fact I do. I should have thought of that before.

Is this like Augat Unilayer?

I do not believe my engineering and math skills are adequate to design it,
but given the specs, I sure could _build_ it. If anyone is considering
this, please bore out the threads of the nut (if you use nuts) before
determining the saturation current. It will minimize mechanical wear on
the insulation. I may just go to the local fastener house and buy a box
of #2 nuts and build a mat of this just to hang on the wall. ;-)
