. Model making; including workshop practice, design and construction of models, a practical treatise for the amateur and professional . Fig. 21—Wooden follower for metal spinning as a face-plate, etc., and in addition overcome the resist-ance to the spinning operation. With a countershaftconnected up so as to run at 450 to 600 , we haveonly to effect a drive of the spindle by pulleys in theratio of 4 :1 to get from 1,800 to 2,400 , no accountbeing taken of the slippage of the belt. There are three or four differences in the lathe asused for metal spinning from the lathe as used for ordi-nary metal turning. These differences affect the head-stock, face-plate, the tool rest and the tail center. The*^dog is not employed. The ordinary center-screw, face-plate or outside scrcAV face-plate used in wood turningis screwed onto the headstock spindle. A block of hardwood, , hard maple, is screwed onto the face-plate andthen turned to the form corresponding to the shape thatis to be assumed by the work at its first stage. The tailcenter is used to hold against it the circular disc of sheet Lathes and Lathe Work
