GERMAN FORMING LATHE FITTED FOR MAKING BICYCLE HUBS. The machine weighs about 4 tons, and admits a 3-inch bar. Its peculiar feature is the massive cylindrical bed around which the tool-holder oscillates. As shown above, four tools are in operation— a borer, one broad-roughing, one finishing, and one parting tool. It will turn out an ordinary cycle hub from the rough bar in about minutes. Made by Pittler, of Leipzig. from the Article THE REVOLUTION IN MACHINE-SHOP PRACTICE. By Henry Roland. Part II THE DEVELOPMENT OF THE AUTOMATIC SCREW MACHINE. from The Engineering Magazine Devoted to Indu
