ABSTRACT:
A method of making an investment or lost foam casting assembly of a first part movable with respect to a second part includes making first and second separate wax or foam patterns of portions of the first part. Then, a third wax or foam pattern of the second part is made. Next, ceramic core pieces are made. At least one of the core pieces is mounted on the first pattern to form a subassembly. The subassembly is combined with the third pattern so that the core pieces maintain a separation between the third pattern and the first pattern. The first and second patterns are bonded together to trap the subassembly and to form a complete casting assembly.
