Less than half a turnof II is enough either to fasten or loosen the Bpindle; and it is worthy of note that this deviceclamps the spindle as nearly as possible to the point of thrust, and never exerts any influence to throw it out of line or centre or to spring it. The centres/ and P are fitted to a conical or taper hole in the re-spective spindles. Some kinds of work cannot be turnedbetween the lathe-centres, but require to be chucked, thatis, fastened by means of bolts and nuts and plates of ironto the face-plate of the lathe, or else to a table or frameprovided especially for the pmpose. In Fig 257Y, C is theface-plate upon which work may be chucked. When, in-Btead of a face-plate, an equivalent is used containing mov-able jaws or other attached devices for holding the work,the term chuck-plate or chuck is used instead of details of the slide-rest construction are shown in Fig. 2580, in whi
