21. About This Machine Foreword The screw cutting engine lathe is the oldest and most important of machine tools and from it all other machine tools have been developed It was the lathe that made possible the building of the steamboat the locomotive the electric motor the automobile and all kinds of machinery used in industry Without the lathe our great industrial progress of the last century would have been impossible How To Run a Lathe 15th Edition South Bend Lathe The lathe represented in this manual is a modern day version of the screw cutting lathes that trace their roots back to the 1700 s which were themselves technological improvements of the bow lathe that can be traced back thousands of years to the ancient Egyptians Now almost 300 years later these modern screw cutting lathes are not just a piece of refined machinery but a culmination of human ingenuity and knowledge embodied into the design and synergy of thousands of interworking parts some of which represent the life s work and dreams of many inventors mechanical engineers and world class machinists including the likes of Leonardo da Vinci Henry Maudsley and the founders of South Bend Lathe John and Miles O Brien And now the torch is passed to you to take the oldest and most important type of machine tool and carry on the tradition As the operator of a South Bend Lathe you now join the ranks of some very famous and important custome
