Get a metal strip tape measure. Start with the factory cut end. Measure 
back, then mark all around the circumference. Score the mark with a 
light saw fitted with a metal cutting blade (hack saw). Once the groove
is scored, cut with a rough cut saw of any type. 

Another option is taking the work to a local craftsman, machine, or
plastics shop. For a couple of $ they will square cut the piece.

This one is accomplished with pure time. It is not easy, and neither
is coil building. Wait until you wrestle a 100 foot length of 1/2 or 
3/4 inch tubing into a 15 turn flat spiral. It takes not days... but
weeks or even months before the conductor is "trained".

I could have (should have?) warned you about this. This material is
much too thin. You need to look at "tupperware" like thicknesses in 
your dielectric... (was that a hint or what?).
