    Neat! Is that a disk-brake rotor under the first-surface mirror?  Hewitt

    My a.h..   The first is made from a plastic cutting board and a second surface mirror.  Look at the back edge in the photo to see the second surface reflection.
    The second is 3/8 inch aluminum plate and if you again look at the back edge you can see the 'first-surface' difference.   The lines drawn on the mirror were suggested on Nav-list, to get the level placed and reversed consistently
