Each jaw (30) of a set of jaw assemblies for a chuck is shaped to provide a locating tongue (13) and a threaded hole to accept a bolt (25). An adapter block (40) has a bottom surface (18) shaped to provide three intersecting slots (17), any one of which slots is engageable by the tongue (13) of the jaw (30). The adapter block (40) is hexagonal and the bolt (25) secures the adapter block (40) to the jaw (30) in one of six different orientations. In use in a chuck, the adapter blocks grip the workpieces. Recesses (19, 20 and 21) of different shapes can be machined in the adapter blocks (40) to allow different shapes of workpieces to be held. |
