Abstract

A wax ring pattern machining tool which enables a goldsmith to create a precision machined wax ring pattern for subsequent casting in precious metal by the lost wax process. The machining operations on the ring pattern are carried out while the pattern is still a part of a wax ring preform tube. The machining tool may be employed to create circumferential grooves or channels on the exterior of the ring pattern or to reduce the diameter of the ring tube or otherwise shape it circumferentially. An indexing function is provided for securing the tool in a fixed radial position, permitting the use of a faceting tool for creating flat or beveled surfaces on the exterior of ring. Upon completion of the exterior design of the pattern, the tool is employed to size the ring and separate the ring pattern from the ring tube preform.
