Drilling machine, Hudson Motor Car Company factory

View of a man operating a converted machine used for drilling forced-feed lubrication holes in the crankshaft of a Hudson Invader engine at the Hudson Motor Car Company factory. Label on back: "From Hudson Motor Car Company. Immediate release. Conversion speed vital output. Here is initiative in quick conversion of existing machinery to get defense products rolling at Hudson Motor Car Company's main plant in Detroit. The goods must be delivered and instead of sitting back and waiting for some hard pressed machine tool manufacturer to make special purpose mac;hines, Hudson engineers built the new and special purpose machine, shown above, by using the parts of three standard machine types, namely, a former engine lathe bed, and two drill press heads with the addition of a specially built feature. The device is for deep hole drilling of the forced-feed lubrication oil holes through the webs and crank pin of the big crankshaft of the Hudson Invader engine. Two of the holes are in plain view. The operation involves drilling holes at an angle from each side of the shaft, to meet at center. Due to inability to secure rapid delivery of such special machinery in time to meet schedules, many such conversions must necessarily be effected to assure early delivery of these vitally needed engines to our armed forces for a second front. More than 750 machines were converted by the Hudson Company for the Invader job alone."
