ATM Re: cheap and easy to build temp mirror holder

["Thomas A Simmons" <tasimmons@raytheon.com>]

Materials needed: 3/4 inch plywood, painted flat black, and protractor or a
piece
of wood with 3 holes (pencil and nail), scribe a zone just outside of your
mirror diameter.
Use 3 screws and place it such that the screws with some shrink sleeve will
just barely
touch the glass. These are there just to keep the mirror from falling, so
Richard's  clips
aren't needed, unless you point the mirror to the ground. From Walmart,
Home Depot, Ace
(etc) get a package of rubber feet (about 1/8 inch in height by 1/2 round).
Assuming
you already figured out the "best" support points using Plop, attach to the
plywood.
There you go, now you can take the mirror and star test to your hearts
content.
