Dear Gents,
Want cheap HV wire? Get some surplus RG-8 or RG-213 coax. Strip
off the outer vinyl jacket & copper braid (this is easy with a razor or a
box cutter). The inner 13-gauge stranded copper conductor is covered with
a thick sheath of clear polyethylene--great for HV work. This wire
is a bit stiff, however.
