Abstract
An improved adaptor capable of coupling a theodolite target with respect to an aperture extending through tooling, the adaptor comprising a cylindrical disk having an exterior surface of a size to be received within the aperture of the tooling, the disk having an interior surface formed as an opening to define a space in which a theodolite target is to be received, the disk having a hole in the interior surface extending radially with respect to the axis of the disk, the hole being of a size to receive the cylindrical base of the theodolite target to be received, a threaded aperture extending through the disk into the hole, and a set screw mounted in the threaded aperture for fixedly securing the theodolite target in position in the disk for viewing from either or both sides of the tooling.
