Conversion. Food machinery plant. John J. Morris used to cut steel disc covers with this universal milling machine. These disc covers were part of the cube steak machines which are the normal products of the New England plant where he is employed. Today, however, Morris used the same machine retooled for subcontract work--the cutting of large hexagonal nuts for a government arsenal. For cube steak machinery there was only one milling wheel, instead of the two shown above. "Hexing a nut" is a very simple job with a machine designed to shape the nut in a single operation, but such a machine is not available and time is short. Morris, therefore, shifts the round steel stock three times, cutting two sides at a time. Cube Steak Machine Company, Boston, Massachusetts
