Jack Gelfand Astronomy and Telescopes-Mirror
Bottom Mirror Clamp
There are slots in the bottom side of the box. The bottom mirror clamp
is a solid piece of pine which is screwed to the bottom inside of the
box. When traveling, the clamp is slid against the bottom front edge of the
mirror and the two screws are tightened to hold the mirror down.
A thin felt pad is glued to the wood so it does not scratch the mirror.
A closeup view of the web anchor is shown on
the next page.
