      Univertical Miller USA
      If you have a Univertical the writer would
      be interested to hear from you

      Although from the illustration it might be thought that the "Univertical" was a floor-standing machine, it was actually small enough - just 37 inches high and with an 11 inch by 18 inch base - to be bench mounted, and was advertised as such by its makers, J. D. Duffy & Son of Detroit. The design for the miller appears to have been bought, in 1938, by Charlie T. Walker (the father of the present president) who then founded a company named the Univertical Foundry and Machine Co. - after "Uni" for universal and "vertical" for vertical milling machine. With the start of World War Two the company, like thousands of other smaller engineering concerns, diversified into strategically important areas including manufacture of the rotating bands used on heavy munitions and artillery shells, forgings for aircraft bomb attachments, brass plumbing fittings, copper hammers and the first nickel balls and nickel bars for the plating industry.  Today the Univertical Company still thrives, continues to supply the Department for Defense and makes state-of-the-art anodes and chemicals for the plating industry,
      Power came from a 1/4 hp motor was mounted on what can only be described as a minimalist (if effective) structure - a single bar, spigoted into an adjustable bracket that wrapped around the upper part of the head and passed through a casting bolted to the side of the motor. Four rather fast speeds were provided that spanned 850 to 3400 rpm. The spindle ran in 1-inch diameter ball bearings, arranged to take both axial and radial loads, but had no form of feed, all alterations to the depth of cut being made by adjusting the height of the screw-elevated knee. The "throat" of the machine, the distance from the centre of the cutter to the inside face of the column, was 6.5 inches.
      Measuring 4.875" x 24" - unusually long for such a small machine - the  table, with 2 T slots, and had a very useful 17 inches of longitudinal travel - and a remarkable 7 inches of cross movement; the knee could be raised through a  distance of 10 inches. One hopes that the three gib-strip adjustment screws provided on the saddle were enough in number to support the table against heavier cuts and to allow a proper adjustment to be made to the sliding fit.
      Priced in the early 1950s at $495 complete with motor the Univertical weighed 350 lbs

      Despite having the appearance of a full-size floor-standing machine
      the Univertical was intended for bench mounting

      The head could be swung 90 degrees in either direction.
