9" Workshop Lathes

9" X 3' Model A Horizontal Drive

As early as 1914, South Bend Latheā„¢ manufactured standard industry 9 inch lathes.  In the early 20's, smaller lathes for students and apprentices were introduced, including a 9" Junior lathe, Catalog No. 22.  The hole through the spindle, horsepower, and other overall dimensions where the same as the Workshop model, and prices, in 1931, were around $300.

In 1935, the first Workshop lathe was presented in catalogs, along with the standard 9" Series O lathe, and the 9" Junior lathe.  It came equipped with a countershaft drive, standard change gears, and a manual apron.  Eventually, the Junior lathe line was dropped.  And by 1939, the first Workshop lathe became Model C, and South Bend Lathe (TM) added a Model A and Model B Workshop lathes with the following units:

Model A lathes have full quick change gear mechanism for threads and feeds; also automatic apron with friction clutch for operating power cross feeds, and power longitudinal feeds.

Model B lathes have independent change gear equipment for threads and feeds, also automatic apron with friction clutch for operating power cross feeds,
and power longitudinal feeds.

Model C lathes, which were manufactured for about four years before the introduction of the Model A and Model B, have independent change gear equipment, lead screw and half-nut power longitudinal feeds and hand cross feed.

Below is a list of South Bend 9 inch and 10K lathes still supported with replacement parts and parts list books.  The catalog number is a portion of the number located on the index plate on the gear box of the lathe. The code designation is included in the serial number, which is stamped between the flat- and v-ways on the tailstock end of the bed.
