Splicing Guide - Heavy Duty Kernmantle Eye Splice



Before beginning splice, slide a piece of 1 x 5 clear shrink tube over the end of the rope to be spliced.


Step 1: Measure in from the bitter end of the rope a distance of 12 inches and mark; this is mark A. Next form the desired size eye and mark; this is mark B. With the eye formed, measure down a distance of 1 and mark both sides of the rope, this will be marks C & D.


Step 2: Approximately 5 or 6 feet down the body of the rope tie a knot and attach rope to a fixed point.

Step 3: Remove all core yarns from mark B as shown in figure below by sliding the cover back on the core to create slack, then bend rope at mark B and carefully remove the core yarns. Once all the core yarns have been removed, removed all the slack from the cover and mark where the core exits the rope, this is mark 1. Be sure not to cross or twist any of the core yarns.

NOTE: Be careful not to catch any of the sleeve yarns while removing the core.


Step 4: Taper the end of the core a distance of 2 and attach to a splicing fid (it is very important that the taper be nice and smooth and that the tape be wrapped very tightly). To taper, fan the ends of the core out and cut at a 45-degree angle. Once the splicing fid is attached insert the core into mark A of the sleeve and exit at mark B, as shown below. Be Sure not to cross or twist any of the core yarns.


Next take the exposed core yarns and separate them in half (i.e: if there are 11 core yarns then separate them into a bunch of 6 and a bunch of 5). When you get the core yarns separated, take the end of the core that has the splicing fid still attached and run it through the center of the separated yarns, as shown below, then bring the separated yarns back together.


Step 6: Now that you have the splicing fid running through the center of the core yarns, insert the fid back into mark A, but move towards the bitter end of the sleeve. Pull the fid out at mark C, as shown below.


Step 7: Take the end of core with the splicing fid still attached and enter to rope at mark D and exit a minimum of 6 inches down the body of the rope, as shown below.


Step 8: Work with the core and the sleeve to get all the marks to align. Once all the marks are aligned mark the core where it exits the rope. Pull core out as far as you can and cut at mark. Taper the core yarns that are left a distance of 2, remember a nice smooth taper. To taper, fan the ends of the core out and cut at a 45-degree angle.

When all the core yarns have been tapered, smooth sleeve out to bury core yarns back into rope. Cut the exposed sleeve back to mark C with hot knife. Whip the throat of the splice for a distance of use the appropriate labeling just under the whipped section. Slide shrink tube over the splice and use heat gun to secure shrink tube to rope.
