Hi All,

The black UHMW that I bought turned out to be highly conductive.  I can 
light a LED to half brightness with two AA cells and a 4" strip of the 
stuff.  It seems that there are two varieties, conducting and non 
conducting.  I am going to look into it's use as a variac brush, as it 
should glide over the windings easier than graphite.  The only bad part is 
the $900 I spent on the stuff, and the almost finished primary form.
