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. In one embodiment, a spindle is milled on the end of the stem. The spindle is milled through the use of a centering tool that slides over the stem and a hollow mill that is rotated by a hand-held power tool, such as an electric drill, which hollow mill is aligned with the longitudinal axis of the stem by the centering tool as the milling operation is carried out. An adaptor, made from a rod having substantially the same diameter as the stem, has a receiving hole bored in one end thereof into which the spindle is inserted. At least one pin is then passed transversely through both the adaptor and the spindle so as to lock rotation of one to rotation of the other, and to prevent the adaptor from disengaging the spindle. The other end of the adaptor has a spline thereon that matches a keyway of the plumbing trim that is to be used. In another embodiment, an axial hole is drilled in the end of the stem into which a spindle of a second type of adaptor may be inserted. The spindle of the adaptor is lockingly engaged with the stem by at least one transverse pin that passes through both the stem and spindle. The other end of the second type of adaptor has a spline thereon that matches a keyway of the plumbing trim that is to be used.
