Abstract: A snap ring removal tool is adapted for removing a split snap ring from a cylindrical shaft. The tool has a receptacle at the end of a handle for holding the shaft lengthwise and ring-engaging means connected to the handle for engaging the snap ring at points on opposite sides of the split in the ring. Urging the ring-engaging means transversely toward the shaft pushes the ring off of the shaft. In one embodiment, the tool comprises a unitary pry bar-like member having a head portion which is laterally offset from a handle portion. The head portion has a longitudinal slot extending toward the handle a short distance to define a shaft receptacle between two parallel legs. A U-shaped shaft guide depends from the ends of the legs. The ring-engaging means is defined by the ends of the legs. A second embodiment is a pliers-like tool which includes two intersecting elongated members pivotally connected together at their intersection.

Abstract: Undulatory rails on a track can be oriented in any given direction by placing the track on a turntable. A wheeled carriage rides to or fro on the track and carries a router. The router bit rises and falls in response to the particular profile of the rails and cuts recesses in an underlying workpiece having shapes dependent on rail contour, bit size and shape and extent of carriage travel. Turntable indexing capabilities facilitate the reproducibility of complex decorative patterns sculptured in the workpiece.
