ABSTRACT:
A tool for precisely sizing wax ring pre-forms used by jewelers and goldsmiths in the manufacture of hand carved jewelry which is readily adjustable to the desired ring size and which is then hand operated to scrape the wax preform to the desired diametral dimension and required depth to obtain a wax ring pattern for the ring to be fashioned. The wax ring pattern having the correct ring size is then separated from the wax ring pre-form stock for further crafting by the goldsmith to shape the exterior of the ring to its desired configuration.
