To simplify instructions, the core was extracted and returned around the outside perimeter of the eye immediately, (see below) so a splicer could see an "eye" and a "methods patent" was born.

McGrew's "Rule of Thumb" Double Braid Eye Splicing Without Marks

Most of the drawings are from the Super Snake methods patent, and the additional helpful drawings are copyrighted. Copying for private use is permitted, commercial use requires "credits."
     1. A 45 degree cut as shown will remove any melted yarns that might snag, and taper the jacket and core with a single cut.
     2. Measure 24 times the rope's Dia (example: 12" on a ½" rope). Extract two yarns from the side of the jacket to serve as Mark A. Once coated with bee's wax, they serve as sail twine, and will be in the right place to stitch the crossover when it is formed, and again at the eye's throat when the splice is completed.

     4. On the right is a tricky labor saver. Keep the point of the awl through the loop of the core as it is extracted, and measure down eight x Dia. (4" on ½" rope) and place a common safety pin as shown. When you are ready to make the crossover, it will be easy to find.

      (Note): Not all braided rope expands and shortens at the same "rate" when the crossover is buried. Old rope requires a few extra tricks. The distance to the safety pin is only an educated guess of the distance needed to shorten the core the proper distance before the eye is laid. Sometimes when splicing used rope, it is easier to move the core the full length of the rope being spliced. You can expand the jacket and bury the crossover much easier. Milking the jacket away from the buried crossover to match its tension to the core is easier than it sounds, and it lets you cut the core off "last not first."
