A pendulous mirror supplies the horizontal reference in the MA-1 Kollsman artificial horizon sextant. The small mirror is mounted at the apex of a small cone and perpendicular to the axis of the cone. The rim of the cone is weighted and the cone is mounted on a needle bearing inside the apex of the cone, the whole is inside a liquid filled compartment for dampening. When we discussed a floating mirror in the past I suggested something similar with a weight like a keel hanging below the float holding the mirror so that the mirror would be leveled by the action of the keel not by the float. gl --- On Mon, 1/24/11, hch <h.halboth@yahoo.com> wrote:
