Patent ID: 6915582

Claim:
A method of aligning at least two pieces of machinery so that centerlines of rotating shafts of each piece are in-line, comprising: a) rotating a first shaft on a first unit, the first unit including a laser holder assembly for projecting a light source around a centerline of the first shaft; b) projecting the light source from the laser holder assembly to a target on a second unit, the second unit having a second shaft; c) adjusting a position of the second unit horizontally and vertically to align a center point of the target with a center of the circle produced by the light source; d) reversing the position of the laser holder assembly on the first unit and the target on the second unit; e) rotating the second shaft on the second unit so that the laser holder assembly on the second unit projects the light source in a circle around the centerline of the second unit to a target on the first unit; and f) adjusting an angular position of the second unit to align the center point of the target with the center of the circle produced by the light source emitting from the second shaft.
