    Re: Making an artificial horizon, and leveling thereof

    Being able to rotate a floating mirror 180* should get the job done. If I were to fabricate an artificial horizon using a standard flat mirror it would involve a shallow nested oversized square floating tray (in water or blue windshield cleaner fluid for below freezing) with a flat 4" x 4" mirror glued precisely at the center of the floating inner tray. Floating foam spacers on all four sides could be used to keep the inner tray sides from contacting the outer tray.
