    Has anyone tried to use a mirror and bubble level as Richard Hubbard
    described in his book "Boater's Bowditch"?  He describes using a thick glass
    mirror with a plywood back and thumb screws for leveling.  What is the down
    side of this and what kind of errors would you expect?  Is the error all in
    the level or are there others?  Thanks.
