This is one of the more popular ways of mounting low friction rings. However, by using a thimble or low-friction ring to create a turning radius that is three times the diameter of the rope, a 1/8-inch line can be used to create a loop of the of the same strength that will only be 10 inches long. Because an eye splice requires a minimum 50:1 bury length (70:1 is better), the minimum practical length of a strop is about 110 rope diameters, or about 20 inches for 3/16-inch line. The most common application of this splice is not to make a line longer, but rather to make a loop. Note that the tail bury must still be 50-70 diameters long and that it must be tapered the same as the long bury splice ( End-to-end Splice Position is important when both ends of a line are loaded.ĭespite its drawbacks, a Brummel splice looks neat and we often use this method. It can be difficult to position the Brummel lock accurately. But this lock will not be enough without being followed by a long bury. In a Brummel splice the line is woven through the weave of the Dyneema rather that passed up the center of the core. As soon as there are a few ounces of pressure, the outer sleeve of the splice clamps down on the buried section, locking it in place. It doesn’t carry any load, it only serves to prevent the tail from slipping out under zero load. In a long bury splice, the stitching is buried deep in the splice. The popular notion is that the Brummel splice is more resistant to chafe, but that is false, as witnessed by the fact that commercial splicing of Dyneema lifting cables use a long bury splice with stitching. Though it looks strong, remember that it is no stronger than the long bury splice, and it does not reduce the need for the long bury. (Remember how you escape from the Chinese finger trap by releasing tension and sliding it gently off your fingers?) Samson shows the full procedure: ( Brummel SpliceĪ variation on the long bury splice, the Brummel provides an alternative to lock stitching. The Animated knots demonstration ( does not show the lock-stitching step-about 4 inches of low-tension big stitches with heavy whipping twine-which is vital to the stability of the knot when not under tension. The taper at the tail avoids an abrupt direction change at the most highly stressed part of the splice and adds about 20 percent to the strength of the splice. The harder the inside line is pulled, the more tightly the outside braid contracts. Like all double braid splices, the strength in the long bury splice is like that in a woven paper finger trap. Eye splices are particularly useful for terminating lines and mounting low friction rings. Key features, such as opening the braid to insert the fid, the long bury, and tapering the end are constants through all 12-strand HMPE splices. The most common splice, as well as the easiest to learn, the eye splice forms a foundation for all of the other splices. You will need a sharp knife and scissors to work with HMPE and they will dull quickly. In the field we’ve used a ballpoint pen, a cooking skewer, and a bit of wire, but that is no way to learn. Splicing always introduces a little construction slack in the line, so the line will stretch back to the desired length over time or after hard loading settles it.Ĭommercial fids make the job easier, but in our demonstrations we are using a cut-off hollow aluminum knitting needle (the angle of the cut is important, and polish it smooth). Every time you bury one line inside another, the rope is shortened an inch or two allow for it. Leave your tails longer than they need to be to start you can always trim them. You can lock-stitch with heavy polyester whipping twine, but you can also pull out a single strand of the rope you are splicing. Work slowly to start snagging a strand inside a rope can ruin a splice.īunching up the cover makes extracting the core, inserting a fid, moving the fid, and sliding the cover easier. Use contrasting colors when practical this makes differentiating between core and cover easier. It is stiff and makes learning difficult. There are only three basic splices, and they are all related.ĭon’t learn to splice with old rope. Even Dyneema lines with a polyester cover, such as New England Ropes Endurabraid, are relatively simple to splice typically 12-strand core is spliced, and the cover is just buried. Fortunately, 12-strand, hollow-braid ropes, like Amsteel, are very easy to splice.
