SAMSON SPLICING INSTRUCTIONS

Double Braid Class I End-For-End Splice

Class I Double Braids are made from any or all of the following

bers: olen, polyester, or nylon.

This splice can be performed on new and used rope. This is an
all-purpose splice technique designed for people who generally
splice used rope as frequently as new rope.

MEASURING AND MARKING

Tape the end of each rope with 1 thin layer of tape. Lay 2 ropes to be spliced side-by-side and measure 1 tubular d length
(or 2 wire d lengths) from end of each rope and make a mark. This is Point R (Reference).

step

1

From Point R measure 1 short d section length (as scribed on the d) then mark. This is Point X (where you should extract
core from inside cover.) Be sure both ropes are identically marked. Tie a slipknot approximately 5 d lengths from Point X.

Note: If you require the rope
with the nished splice to
be a certain overall ength,
refer to “Special Tips for
Splicing Double Braid
Class I”, on th last page
of these splice instructions.

EXTRACTING THE CORE

step

2

Bend rope sharply at Point X. With a pusher or any sharp tool, such as an ice pick, awl, or marlin spike, spread cover
strands to expose core. First pry, then pull core completely out of cover (shown in white) from Point X to the end of rope.
Put 1 layer only of tape on end of core (shown in gray.)

To assure correct positioning of Mark 1 do the following: holding the exposed core, slide cover as far back towards the

tightly tied slip knot as you can. Then, rmly smooth cover back from the slip knot towards taped end. Smooth again until

all cover slack is removed. Then, mark core where it comes out of cover. This is Mark 1. Do this to both ropes. (Fig. A)

Do not pull cover strands away from rope as this will distort cover unnecessarily.

Hold 1 core at Mark 1 and slide cover back to expose more core. (Fig. B)

From Mark 1, measure along

equal to the short section

MARKING THE COVER FOR TAPERING

Note nature of the cover braid. It is made up of strands. By inspection you can see that half the strands revolve
to the right around the rope and half revolve to the left.

Beginning at Point R and working toward the taped end of cover, count 8 consecutive pairs of cover strands
that revolve to the right (or left). Mark the 8th pair. This is Point T, which should go completely around cover.

Starting at Point T and working toward the cover’s taped end, count and mark every second right and left pair

of strands for a total of 6. Then, on the other rope starting at Point T, count and mark every second right and left
pair of strands for a total of 6. Make both ropes identical.

PERFORMING THE TAPER

Bring cover-tail down on side
of rope (minimum 2 times rope
circumference in inches) and lock
stitch (or tape) excess cover to
rope. After lock stitching, excess
cover should be whipped to the
neck of the rope with appropriate

whipping twine. Start whipping at

the throat of the eye moving toward
tail using Whipping Method 2.
