I'm skeptical about this, the friction of 700-1000 tight turns of magnet 
wire could make this very difficult if not impossible to slide off.  I 
think you're right about having some kind of film between the tube and 
the wire, so that the varnish is not adhering to the tube, but I think 
the tube should still be cardboard.  The soak until soggy method sounds 
more promising to me than fighting the friction.
