Railway mechanical engineer . ith those in thecylinder, care should be taken that the lug or bracket onthe back of the cylinders is about 34 in- above the face ofthe machine table, this is to allow for irregularity inmeasurements from the center of the cylinder to the faceof the bracket. This device can be constructed at a small cost, and itwill be found to save time in doing the work and give moreaccurate results. The principal advantage of this deviceis that the cylinders are always bored true with the face,and that the distance from center to center of the cylindersis also maintained. The

There is no necessity for resetting afterreboring one cylinder; simply draw the table to the othercenter line and change the heads on the boring bar. Whensetting up a c\linder, line up under the brackets on thecylinder and place a clamp on each end. This will holdthe work more rigidly. BALL BEARING PIPE CENTER BY E. A. M.
