There is scarcely any limit to the number of styles and sizes of chucks which can be used for wood turning. For elementary work only a few are required.

The screw chuck, as shown in Fig. 268, is the one most often used. The spur chuck (Fig. 275) is very handy for some work. Other styles, except the wooden cup chucks which are often used as shown in Figs. 165, 168, 169, and 227, may be dispensed with for all ordinary work. The cup chucks are very simple appliances, being merely blocks of wood, secured to a face-plate, and hollowed out to receive the work.
