Abstract
A foundry core is disclosed for molding a cast blank machinable to produce a crosshead piston head member. The core shapes an exterior surface region of the blank section corresponding to the ring belt in the machined product. The core-shaped exterior surface provides a readily accessible reference for accurately positioning the core during subsequent machining operations.
