An apparatus and method for aligning an internal combustion engine block to be bored by a vertically movable boring tool so that the center of rotation of a crankshaft to be mounted within the engine block is perpendicular to the direction of vertical movement of the tool.

Engine boring fixture

A damper for use with work arbors supported at only one end is disclosed which acts to reduce harmonic vibration and chatter as the arbor rotates and a cutting tool operates on the workpiece. The damper consists of a damping collar, with an interior radius greater than the exterior radius of an associated spacer, which freely rotates on that spacer such that the collar rotates independently of the work arbor at a speed of about 66% of the arbor's speed and acts to suppress undesirable chatter, and harmonic vibrations.
