3-Strand Tuck Splice
Class 1 3-strand ropes are made from any or all of
the following fibers: Olefin, Polyester, Nylon
Although the 3-strand splice is the most common splice,
and simple to perform, technique is important to preserve splice strength.
Take care that the tucks lie neatly; rope strength can be lost if the
strands are twisted incorrectly.
Tools Required:
Fid; tape or whipping twine;
marking pen, scissors or a sharp knife; hot knife or heat source; ruler.
Getting Started: From one end of the rope, count
back 16 crowns. Tape this section. unlay the rope up to the tape then tape
the end of each strand. Form the eye and tape the standing part of the
rope. To avoid a twist in the eye of the finished splice, untwist the rope
one-half turn between the pieces of tape.
STEP
1 ... TUCKING THE FIRST STRAND
With a fid or your finger, raise a
strand just below the tape on the standing part of the rope and insert the
middle working strand under the fid and pull the strand through. Mark the first
tucked strand with a single hash mark; numbering the working strands will
help you keep track of the tucking process.
STEP 2 ... TUCKING THE SECOND STRAND
Using the fid to separate strands, tuck the next working strand over the
strand you just tucked under and under the strand just below it. Mark this
strand with a double hash mark.
STEP 3 ... TUCKING THE THIRD STRAND
Turn the entire piece over. There is one
working strand left to tuck and there is one strand left in the standing
part of the rope that does not have a working strand under it. Insert the
fid to separate the strands and make this
tuck, continuing to work counter to the lay or twist of the rope. Mark
this strand with a triple hash mark.
The first round of tucks is complete. Tighten if necessary by pulling on the strand ends.
When you tuck,
take care to use all three strands in each round and that you tuck under a
strand in the standing part of the rope and not under one of your working
strands.
STEP 4 ... FINISHING THE SPLICE
Perform four more complete tucks.
Tighten tucks if necessary. Both the front and the back of the splice
should resemble the illustrations shown.
