The lathe may be used to do almost any work that other machine tools can do if supplied with the proper attachments. Drilling, grinding, milling and boring may be accurately performed by using various attachments to be described in proper sequence. We will first discuss the methods of doing simple jobs and then will show some methods pertaining to harder work. A number of lathe accessories that are inexpensive, yet very useful, are shown at Fig. 320. The spur center at A is used in wood turning, especially for long work. It is intended for use in the lathe spindle and not only supports the work but drives it as well when the spurs or lips are forced into the end of the piece to be turned. The screw center B is for turning large wood pieces that cannot be very well supported by both head and tail stock centers. The cup center C is used in connection with either of the others in wood turning and is generally used in the tail stock. When drilling with square shank drills and bits the special drill chuck at D will be found useful. The form shown is provided with a female thread to fit the lathe spindle nose. The drill or bit is clamped in place by a set screw. The drilling pad with V groove shown at E, sometimes called a crotch center, is very useful when drilling round bars as it supports these and centers them automatically. The drill pad shown at F is used in the tail stock (as is the crotch center E) as a support for any piece drilled, and is designed for use with flat stock.
