Fig. 2554. G, cast-iron frame to sup-port upper end of boring-shaft. Fig. 2555 shows the stand or bedindicated by letter C, Fig. 2551, onwhich the cylinder rests which is to bebored out. Fig. 2556 shows a guide, indicated byD, Fig. 2551, which is placed upon topof cylinder, and serves as guide for bor-ing-bar. The boring-bar is then con-nected to the revolving-plate, as shown. 204 LATHE. in B and E, Fig. 2551, and turns with it. The boring-head which holds the cutters is shown at G, and isconnected with two screws nearly the whole length of boring-bar, set in grooves and moving with the bar,and shown by dotted lines, which screws regulate the descent or feed, as it is termed, of the boring-head
