I found a place to buy a sample of Kapton tape for $10 shipping. It'll
be here soon. A 1.5 inch roll would have been $35 plus shipping, and I
don't intend to make more benders.

I am still kind of interested in milling the element grooves round
instead of V. That, and some high-temp epoxy, would take stress off
the tape.

We'll see how it shapes up.
