ABSTRACT:
An instrument for determining the alignment of two objects includes a support in the form of a cylindrical body having a longitudinal axis. The support has means on one end for releasably mounting the support in an opening in one of the objects being aligned. The support fits into a recess in a housing which can rotate about the longitudinal axis of the support. A gauge carrier is pivotally mounted on the housing. A gauge is mounted on the gauge carrier and has a finger pivotally mounted thereon and projecting therefrom. The gauge is adapted to detect pivotal movement of the finger. The finger is adapted to contact the other object and as the housing is rotated about the support will pivot toward or away from the longitudinal axis if the other object is not in alignment with the one object. The pivotal movement of the finger is detected by the gauge.
