Abstract: A process for making a product having a dimensionally critical aperture extending therethrough comprises placing a sized elongated pin in a predetermined position through a mold cavity. A body is cast in the mold cavity for use in a lost-wax process. The body is then reproduced in metal by the lost-wax process. The pin is carried along with the cast body so that the body constructed in metal bears the pin at the location of the intended aperture. The pin is thereafter dissolved from the metal body.
