Conversion. Food machinery plant. This turret lathe was purchased second-hand from a nearby shoe factory to speed production on war subcontracts held by a New England plant which formerly turned out cube steak machinery. Edwin Becker is checking on a retooling job in progress which eventually fit the new lathe to thread three-and-a-quarter-inch hexagonal nuts. Becker is checking the measurements of the tool hole in the turret with those of the specially-built tap which will do the threading. Cube Steak Machine Company, Boston, Massachusetts
