I'm not smoking anything.

I have obtained several pieces of highly polished marble.  One piece will
become a reference slab for machine work and other measurements I may need
to take that need a mechanically flat surface.  The others will become the
basis of a new Focault tester.  Think it will work?

The second idea is a little stranger.

I have read about many different spider vane materials, from mild steel to
guitar strings to brass to a single thick post.  I may take the guitar
string idea a step further with the use of .75" width, .5 mil VCR
tape.  It's mylar and very strong.  I'm wondering if this material will
work to support a diagonal or Cassegrainian mirror in a smallish (8"
to 14") telescope?  Has anyone tried this?
