scrawled the following:

Hi all,

I want to build up a magnetic core using a few hundred feet of 0.023"
diameter ER70-S6 MIG filler wire. To limit eddy current, I need to make
the wire non-conductive to low voltage (ca. 5.0V AC @ 60Hz) up to 100
degrees F (38 C).

Right now, I'm contemplating a monstrosity full of pulleys and motors,
to apply several coats of polyurethane liquid with intervening drying
stages.

I am aware of McMaster 8867K25 which is a 0.062" diameter vinyl insulated
mild steel wire. At only 249 feet per roll, I am concerned about the
need for splices, though.

How would you approach this particular challenge?

Buy from McM and splice, then cover the few (soldered) splices with
shrinkwrap. Trying to _evenly_ coat wire will haunt and taunt you to
your grave, Winnie.

For me, pragmatism is not enough. Nor is that fashionable word "consensus."

To me consensus seems to be the process of abandoning all beliefs,
principles, values and policies in search of something in which no one
believes, but to which no one objects; the process of avoiding the very
issues that have to be solved, merely because you cannot get agreement
on the way ahead. What great cause would have been fought and won under
the banner "I stand for consensus"?
--Margaret Thatcher (in a 1981 speech)

LJ sez: It's a good thing we have concensus on the case of Anthropogenic
Global Warming (kumbaya), isn't it?
