Paul,

While the quality of that wire sounds somewhat unacceptable, i dont
think it will be a problem for a TC secondary.  Just make sure you
varnish it well when you are done.  Ive wound some coils with very
cheap wire (insulation flakes off after a few bends) and still managed
to push those coils very hard and never experienced any failure in the
winding or anything like that.
