A locator device for locating the centerline of a plurality of piano hinge segments without the use of hard tooling includes a target support element, a pair of targets supported on opposite ends of the target support element, and a locator element for locating the target support element relative to hinge pin holes so that the targets are equally spaced from the hinge pin holes. The targets may be reflective-type targets used in laser targeting systems, photogrammetry targets used in digital photogrammetry locating systems, or other known targets.
