Abstract
A method and means for adapting a stem of a plumbing valve for use with plumbing trim of a type for which the plumbing valve stem was not originally designed to be used. A bore is drilled into the end of the stem using a conventional hand-held power drill and a special centering tool that provides a first guide hole in alignment with the longitudinal axis of the stem. A transverse hole is also drilled into the stem in alignment with a second guide hole provided by the centering tool. An adaptor, made from a rod having substantially the same diameter as the stem, has a shaft at one end thereof for insertion into the bore drilled into said stem. At least one pin is then passed transversely through both the shaft of the adaptor and the trim to lock rotation of one to rotation of the other, and to prevent the adaptor from disengaging the stem. The other end of the adaptor has a spline thereon that matches a keyway of the plumbing trim that is to be used.
