[kch] Although I've not done it, I feel intuitively that simultaneously
winding fishing line & wire is something I don't want to tackle. I'm
contemplating the winding-on first of a cotton twine to form a spiral
track, with winding-pitch larger than the wire diameter. After
stabilizing that with, perhaps, a very thin varnish or "water seal"
preparation, I would then wind the wire over the twine. Comments,
anyone?

[kch] To the provider of the $.02 (Is it Mike H?): You make a very good
point. Better to fill that space with a solid non-conductor. Porcelain
would be nice. But more seriously, doing essentially as you suggest.
But then, what does one do about inadvertent carbon-tracking? More
comments, anyone?
