Jerry,

IIR, there was a discussion in an article from some very old publication
about the hose clamp idea, called the Prince Albert. It was reported that
the Prince Albert works only with a perforated mirror.

I got the idea while reading "Kinematic Design in the 21st Century" by Izzy
A. Kidder (third edition published by Phantom Books).

Jerry,

Where did the hose clamp method come from? Bernard Schmidt's original method
for producing an asphere by deforming surfaces and polishing a sphere used a
vacuum and annular support.
