ABSTRACT:
A plastic deformation is imparted to each of a sequence of load determining elements with the amount of deformation matching each element to a corresponding one of a sequence of element receiving workpieces to compensate for dimensional variation between the workpieces. A first fixture portion is abutted to a first workpiece portion and a second fixture portion is abutted to a second workpiece portion to provide a dimension defining separation between the fixture portions which is a function of a variable dimension of the abutted workpiece. The load determining or spacing element is then deformed the amount required for the particular abutted workpiece and the sequence of steps repeated to provide a plurality of matched elements and workpieces. The amount of element deformation may be such that the elements are under a like compression when assembled in each workpiece, thereby preloading the workpieces by consistent amounts or the deformation of the load determining elements may be sufficient that each workpiece has a small amount of free movement after assembly of the elements within the workpieces.
