  • Screw Sizes For Original AO Pilot

    Does anyone know the exact screw sizes for the original 70's AO Pilot frames?
    Takes two different sizes.
    Total of four screws.
    And possibly a source for a hobbyist rebuilding a frame?
    Thanks

    Start with a 1.2 and if it slips through move up from there to 1.3 etc., until one tightens with no resistance!!!

    I think they were 1.3 eyewire and 1.4 temple.

    Check Hilco's catalog for various length as well.

      They would have pre-dated the use in the US of metric sizes I seem to remember that the larger (temple) screw would be the equalivant of 1.37mm.
