Centering Tool
A small, steel point used for accurately locating centers. Fig. 58 illustrates the O. K. centering tool, which is made to fit any tailstock spindle or taper chuck. This tool is inserted in the tailstock spindle and the work to be centered is placed in a chuck or is cemented up on a cement plate. The work is now rotated and the tailstock advanced and the tool will cut an exact center, providing the work in the headstock is central. This tool will be found useful in determining centers when pivoting staffs and in drilling generally.
