Fig. A—Profiling Front Ends of Main Rods, Using the Circular Feed vide a boring bar guide when taking heavy boring table saddle has a longitudinal travel of 44 in. from aposition with the center of the table 16 in. to the right ofthe spindle center to a point 28 in. to the left of the center. April, 1922 RAILWAY MECHANICAL ENGINEER 229 The cross feed is efltected by the movement of the spindlehousing on 8-in. ways with a spread of 46 in. over all. Thealinement of the housing is maintained by two gibs, one oneach way, and one clamp, bearing on the under side of thebedway, is provided on each side. The total travel of thehousing is 30 in.; the center of the spindle at the forwardlimit is one inch in front of the center of the table. Thespindle housing carries all of the speed and feed changes,with the gears located in two oil tight pockets in the spindle is 6 in. in diameter at the largest taper and hasa 10-in. flange. It is carried in a 10-in. quill which has ave
