Claim 0:
1. An apparatus for concentric alignment of cylindrical components comprising:
an object having at least one outside cylindrical surface and at least one alignment target;
an inner aligning component having at least one outside cylindrical surface having an axis and at least one inside cylindrical bore having an axis parallel, but not coincident (eccentric), with the axis of the outside cylindrical surface;
an outer aligning component having at least one outside cylindrical surface having an axis and at least one inside cylindrical bore having an axis parallel, but not coincident (eccentric), with the axis of the outside cylindrical surface, wherein
the at least one cylindrical surface of the object is adapted to fit rotatably into the at least one inside cylindrical bore of the inner aligning component,
the at least one outside cylindrical surface of the inner aligning component is adapted to fit rotatably into the at least one inside cylindrical bore of the outer aligning component, and
the alignment target is oriented in an aligned position relative to the outside cylindrical surface of the outer aligning component by rotating at least one of the object, the inner aligning component, and the outer aligning component.
