Jeweling
The act of fitting in jewels for pivots to run in, to diminish wear of the acting parts. Sapphires and rubies are used in the better class of work, while in cheaper watches garnets are substituted. In escapement holes, where endstones are used, as in Fig. 181, the jewel in a loose setting is fitted into a recessed hole, and upon it the end-stone, also set in metal, is laid, and the whole secured by two small screws. In cheaper movements the jewel is rubbed in, as shown in Fig. 180.
