[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?
