U.N.D. Lathe


Around 3.5-inch centre height, and 20 inches between centres, the U.N.D. was a precision bench lathe* distinguished by a dividing attachment, complete with indexing plate, built into the front face of its plain-bearing headstock. Only two surviving examples are known with the one shown fitted with a Goodell-Pratt compound slide and, by the appearance of its many home-made accessories, has enjoyed a hard and productive life. Unusually for a lathe of the late 19th and early 20th century, the 3-step headstock pulley is overhung and, as the headstock spindle finishes well inside and has a gear on its end, may well have originally contained an epicyclic reduction gear to obtain low speeds. 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 two survivors came from a long-time employee the University Of Notre Dame and the lathe might well have been one of a small batch assembled by students as part of a project. The university was well known for its interest in things mechanical and in 1939 research at the university was supported by the establishment of a fellowship in metallurgy and allied sciences 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.

The over-hung 3-step headstock pulley may originally, judging by the gear on the end of the spindle, have contained an epicyclic reduction gear

Goodell-Pratt compound slide rest

No mistaking the manufacturer's name - the letters U.N.D. were cast into the front face of the bed.
