Abstract
A method of providing an internal circumferential shoulder in a cylindrical passageway including the steps of forming an enlarged internal diameter groove in the passageway, machining an integral unitary circumferential shoulder blank of external dimensions conforming to the groove, cutting the shoulder blank into at least segments, each segment having opposed end surfaces that match the end surfaces of adjacent segments, the opposed end surfaces of one segment being defined by parallel, spaced-apart planes forming a key segment, positioning the shoulder segments into the groove, the key segment being inserted last and securing the key segment within the groove.
