The method comprises forming four like, and interfitting molds, with cavities therein, and closing all the molds together in envelopment of a cruciform element. The element, preferably, carries bearings on opposite ends of the pins or shafts thereof. Casting material, such as high tensile bronze is introduced into the molds cavities to cast the end product therein, onto the cruciform element and bearings. The method has particular application and utility in the casting of assemblies of articulatable components, such as universal joints, and the like, in that it affords the fabrication of such assemblies, complete, in a single casting operation. The casting means comprises a mold which is interfittable with others thereof for use in the practice of the above-noted method.
