Around 3.5-inch centre height, and 20 inches between centres, the U.N.D. was a precision bench lathe* distinguished from others of the same genre by a dividing attachment, complete with an indexing plate, built into the front face of its plain-bearing headstock. Only three surviving examples of the U.N.D. are known; one is fitted with a slide rest of the correct type from a late-model Cataract precision bench lathe while another has an example as fitted to the rather less expensive Goodell-Pratt. The latter machine, by the appearance of its many home-made accessories, had enjoyed a hard and productive life.
Unusually for a lathe of the late 19th and early 20th century, the 3-step flat-belt headstock pulley was overhung and, as the headstock spindle with a gear on its end fnished well inside it may originally have housed an epicyclic-type speed reduction unit. Another seldom-found fitting is a built-in headstock-mounted dividing attachment, the cover over the centre part of the spindle presumably guarding a worm wheel.
Unfortunately, with an absence of sales literature, it is impossible to tell anything of the maker's background - although it is confirmed that one of the three survivors came from a long-time employee the University Of Notre Dame and the lathe is likely to be one of a small batch assembled by students as part of a project. The university was (and still is) well known for its interest in things mechanical and in 1939 research into metallurgy and allied sciences was supported by the establishment of a fellowship in by the gift of $15,000 from Mr. J. J, O'Brien, owner of the nearby South Bend Lathe Works.
If you have a UND lathe the writer would be interested to hear from you.
