They had both spent their early working years at the Stanley Works; Miles worked for Thomas Edison for a time, and then the two of them studied engineering at Purdue University.After working for several years around Indiana, they founded their own firm to build a machinist lathe whose design they had been refining for many years.After that date, a new numbering system added a three letter code to indicate 1) the swing, 2) the gear and apron combination and the location of the drive, and 3) the spindle hole size, type of swing, and special features. It has quick change gears, friction feed apron, and underneath motor drive, a large spindle hole, and standard swing.The number 7 is the model number, which is changed when modifications are made to the machine that do not change its overall characteristics.Jacobs chuck, some countershaft pulleys, and a interesting little Skinner 4 jaw chuck. Here is one of a 11 inch out of a Sears 1914 catalog that shows how the lathe was setup.The 10 and the 11 used many of the same parts and looked the same." DT , The plain brass bearings have been re-honed and re-shimmed. The castings have been sandblasted, painted a neutral machine gray, all rust removed, polished and re-assembled with all the original parts of the core machine.
is stamped on the tailstock end of the bed between the flat- and v-ways.
Such items might have been Examples include the top of the leadscrew hanger bearing bracket, the changewheel bracket, the leadscrew, on the concealed surface of the rack where it abuts against the bed and on the inside of the apron, etc.
The serial number is stamped on the tailstock end of the bed between the flat- and v-ways.
Until a change of policy in 1947 - and a production total of approximately 186,500 lathes - South Bend used a simple sequential numbering system, but after that Serials were broken down between different types of lathe with numbers assigned sequentially within a group.
Adding the highest number seen in each category post-1947 to pre-1947, gives a total production of just a over 330,000; however, by the 1970s, South Bend's range was very limited and most of the lathes produced during the last 30 years of the 20th century were the eternally-popular model 10K - a direct descendent of the original 9-inch lathe of the 1030s.
This would originally have been treadle powered but was converted to a bench machine.
