                                                               will find it worthwhile for greatly reducing setup
                                                               time and effort while improving splice quality.
                                                                  The third basic ingredient is a spike. For this
                                                               size wire, a Snap-On scratch awl (#7ASA) is perfect,
                                                               once you file a flat, rounded tip on it (Figure 6-19).
                                                                  You’ll also need some nippers to trim the splice,
                                                               a mallet (see Figure 6-37)—preferably of hardwood,
                                                               brass, or lead—to fair it, a bit of seizing wire, and
                                                               safety goggles. One more item: an unlaying stick
                                                               (shown in Figure 6-21B). It’s a stick with a braided

                                                               making it easier to enter the spike into the wire.

                                                               Setting Up
                                                               The first step in making a splice is to put a wire
                                                               seizing on the wire rope near the rope’s end (Figure
                                                               6-20). It will keep the wire from unlaying too far
                                                               and will make it easier for you to put an even strain
                                                               on all strands. The formula for the seizing position
