The parts of the lathe, when equipped for metal spinning, which differ from corresponding parts when the lathe is used for metal turning, are the headstock, faceplate, tool-rest and tail center. The dog which is so commonly used in the metal work ing Shop to hold work from slipping in the lathe as it revolves is never used in metal spinning. The ordinary center screw faceplate or outside screw faceplate used in wood-turning is screwed onto the headstock spindle. Upon the faceplate is screwed a block of hard wood, usually hard maple; this is turned with wood-turning tools to the shape de sired for the first form in the process of spinning. The circular disk of metal which is to be spun is centrally placed against this turned form and held in place by the tail center which is brought in con tact with it. Prior to the time when spinning be gins, the circular disk of metal is held in place by friction between the wooden form fastened to the faceplate, over which the metal is to be spun, and the tail center. The process of Spinning will be de scribed later.
