The method of preparing the wire rope for these sockets is the same whether hoops or rivets are used. First put a strong wire whipping on the rope at about the length of the socket from the rope-end. Untwist the wires of the part left over and straighten them out (see Fig. 195); then bend them sharply back, one or two at a time, over the whipping and over the rope. If the rope has a wire core in the centre, the wires forming it should be bent back the same as the outside wires; but if the core is of hemp, it must be cut off close to the whipping. After hammering snug and close, all these wires have to be cut to a different length, so as to form a tapered bulb corresponding to the tapered cavity inside the socket. Cut the longest wires an inch or two shorter than the length of the socket, measuring from A to B (Fig. 193), and gradually make the other wires shorter and shorter all the way towards the end. These wires must now be tightly and closely served with soft copper wire or spun yarn, using the serving-mallet already described in this chapter. For common work spun yarn is used, and for the best class of work soft copper wire.
