Abstract
A bore centering apparatus includes an elongated level having a laser beam generator at one end insertably received into the center of a centering cone placed within a hole in a wall. Adjustment of the level is made by turnbuckles which adjustably connect the level to the front face of the wall into which the centering cone is placed. The laser beam generator transmits a beam through the centering cone along its central longitudinal axis and therefore is coincident with the central longitudinal axis of the hole so that the beam terminates at a remote or spaced-apart intended target. Offset lines in degrees are carried on the external surface of the centering cone so that layout directions can be derived quickly. A protractor plate may be incorporated into the assembly at the base of the centering cone to set the desired degree of offset. By combining a 45 degree or 30 degree offset mark on the bore cone, the bore assembly is tilted accordingly to show compound angle layouts or directions of mechanical runs.
