Spectra Loop Splice




Below, a simple splice is illustrated on 1/8" single braid spectra rope. There are other, more complicated but secure methods of eye splices. Some will not allow splicing of both ends of the rope as this example does. Whipping of the splice is required to ensure that the splice doesn't work its way out.

Tools required:

  • Sharp scissors, razor blade or knife
  • Fid: solid rod of appropriate diameter and length ( 3/32" Ti rod used in example)
  • Fiber tape: cut width wise to allow for overlapping circumference of rope

Step 1: Lay Rope and Fid Longitudinally at One Side of Fiber Tape. Allow a Gap Between Ends.

Step 2: Oll Fid and Rope Up in Fiber Tape

Step 3: Open Weave of Rope and Push Fid Through From One Side Through the Other

Step 4: Pass Fid Through Rope Again From the Other Side

Step 5: Open Weave of Rope on One Side, Close to Where the Fid Tail Has Come Through. Carefully Feed Fid Down Interior of Rope for a Few Inches and Then Let Fid Exit Center of Rope.

Step 6: Pull Fid Tail Until Eye Remains and the Section of Rope Covering the Tail Is Bunched

Step 7: Cut Fid Tail and Stagger Lengths of Individual Strands of Tail. This Allows for a Smooth Taper in Splice

Step 8: Milk Cover Over Tail Until Tail Disappears Into Rope and Rope and Splice Are Tight

Step 9: Use Waxed Whipping Twine to Set Splice. Notice Tail of Twine at Left and Loop at Right

Step 10: Tightly Wind Twine Around Splice Working Towards Loop (from Left to Right)

Step 11: When Sufficient Whipping Is in Place to Cover Splice, Cut the Twine Free From the Spool Leaving About 6" of a Tail. Feed This New Tail Through the Loop at Right.

Step 12: While Holding the Tail at Right, Pull the Tail on the Left Until the Loop Disappears Under the Whipping Coil and Is Pulled Almost All the Way Through. in Photo Above the Loop Has Yet to Disappear.

Step 13: The Loop Is Now Inside the Whipping Coil. by Pulling Tightly on Both Tails, the Whipping Coil Gets Tighter on the Rope Splice As Well As on the Tails. Keep the Loop Centered Under the Coil (from Left to Right)

Step 14: Cut Tails of Whipping Close to the Whipping Coil. This Whipping Is Completed, But in This Example, the Whipping Doesn't Cover the Splice Nicely - DUH!! (For Ease of Photography Proper Placement of Whipping Was Ignored)

Step 15: In This Photo, Whipping Was Redone, With Proper Placement Over Splice in Rope

    While this is likely to hold for anything you might use it for, the
    proper knot for 12 braid hollow core line (like Spectra) is the Brummel
    splice. In the knot you use, the tail could conceivably work its way
    out by reversing the steps you use. The Brummel passes through the line
    twice (as this one does) but once by the head, and once by the tail.
    Thus it is not reversible. This means you need a free head and tail,
    but there is a way of doing it (really clever) by everting the pass
    throughs and then re-verting them to make the proper knot. There is an
    animation at Greg's knots:


    Done this way it doesn't need a whipping (not such a bad boy) but a good whipping does look pretty classy...

    Thanks for showing the tricks about a wire fid and the nice whipping demonstration.

    p.s. I realize this is an ancient post, but the link above may be valuable to someone...

    If whipping twine is not available, one might use waxed dental floss. As mentioned elsewhere this is a well done "Instructable" and appreciated

    thanks. this instuct has given me all th steps that I was missing, for this step i do remember that you should mark every fifth(5) strand along one side and use that placement to make your reducing cuts. This will make the tail longer but you will have a smoother splice and the original strenght of the line will be regained. (please correct me if i have remembered this incorrrectly.

    "milk" as in milking a cow...work the cover downward from the loop to bring the exposed tails into the cover.

     No it's not actually, I got it off some other site. You do realize that for every picture on the internet, there is probably 100 other copies of it.

    dude its like platting if u no how to plat u can splice i was tought at a young age of 13 forget now but i picked up how to do it in like 10 mins serch on the net im sure it wil tell u how to do it honestly ild rather tie a knot then worrie bout doing this u only really use eyes for boating and that eye looks to small if u ask me with my boating back ground

    I need to know how to braid a loop in the end of three strand twisted nylon rope. (3/4" dia. rope)

    I don't think this will work with my 2 inch line. I guess I will have to keep doing it the other way.


    11 years ago on Introduction

    instead of using a fid, you can get some wire(I don't know the exact name of the type of wire, but it is thick and will stay good and tight if you bend it over) so bend the wire over and tighten the bend with some pliers so that it is very very tight. then feed it through the place where you want to bring the rope through, then slide the very end of the rope so that the wire pinches it. make sure it is good and tight. you can then pull the rope through. no need for tape or anything

    to 'milk the cover over the tail', I took it to mean dragging and pulling the cover until the tail disappears inside.

    I love this instructable and as someone else mentioned, the photos are fantastic. Whenever I'd seen this loop on the end of a rope, I always assumed it was a complicated weaving process using about 7 pairs of hands or specialist tools. Thanks for introducing me to this "fid" thing :)

    I"ve always wanted to know how to do this, thanks! I love this website,

    On a related topic...does anyone know how to tie an electicians loop? It might also be called a monkey ladder. It's hard for me to describe but it looks like a series of loops where the current loop nestles into the previous loop. And you pull it on one end,and the entire loops comes apart without tangling.
