View of workers operating combination radial arm router and drill at the Hudson Motor Car Company, Aircraft Division. Label on back: "Huge machines speed Hudson warplane production. This huge machine in the Aircraft Division of the Hudson Motor Car Company is known as a combination radial arm router and drill and is used to cut out or route and pre-drill aircraft metal sheets in multiple. Sheets to be cut are stacked on the table and as many templates or patterns as possible nested together on top of the sheets which allows the machine to cut out the various shaped patterns from many sheets of metal in one operation. The drilling of multiple sheets is accomplished by the drilling radial arm at the extreme right. This machine, which eliminates the necessity for blanking dies, is typical of the new devices now in use by Hudson to speed up defense production of aircraft." Handwritten on back: "Conversion."
