Well, way back when, you could not get decent resistor wires, resistor plugs were erratic, and I had a lot of radio equipment on my Jeep.
My father's M38A1 had copper braid shielded wires, shielded spark plugs, and a metal top magneto.
Of course, being the civilian version, mine was not shielded.
Went to a friend's shop, and we figured a way to copper plate a set of plug boots. Then I took some mil-spec RG-8, and made myself a set of plug wires using those boots with the braid solder tacked to the boots.
Cranked it up, and it ran great. Had some ignition noise, but not much, and I figured I could track it down later.
The copper plating had cracked on the boots, so I was planning on some kind of shell I could put over them.
Left the shop, started down the road. Lost the first cylinder about a block away. Spun around and headed back.
Coasted in on, I think, two cylinders.
So much for that idea........
I had deliberately used the kind with the hard green plastic dielectric, figuring it would hold up better than the foam, but it arced through anyway.....
