A number of short bushings such as that shown at A in Fig. 4 were to be refinished on the outside. The bushings were of various diameters ranging from 2 1/4 to 4 inches, while the lengths varied from 1 1/2 to 3 inches. The pieces were held on arbors B, in collet jaws C. A split sleeve D was expanded inside the work by the action of collar E and nut F. The body of the tool G was secured to the dovetailed face of the turret by gib H. The tool-slide J is a steel casting dovetailed at P and fitted with an adjustable taper gib to take up the wear. The cutting tool K is placed in a slot in the slide and is secured by the screws shown. The screw L is journaled in a lug at the upper end of the slide and enters a steel nut M in the body of the tool. Radial adjustment is obtained through this screw by means of the handwheel N. The rim of the wheel is graduated and the pointer 0 permits accurate readings to be made. This tool is very good indeed for light work, and accurate results can be obtained by its use. When two tools are used, a tie-rod Q assists in making the combination more rigid.
