LONG AND SHORT SPLICES (MULTI-STRAND BENDS)
2646. A FOUR-STRAND OVER-AND-UNDER SPLICE. In the illustra-
tion, for the sake of compactness, the splice is shown tucked
only once at the left and twice at the right. The technique is the
same as already described. But as four-strand rope is not so firm as
three-strand rope, each strand should be tucked at least twice full,
then once one half, and once one quarter. The last tuck in any FOUR-
2.646
STRAND SPLICE should always be under two strands whether the
splice is long, short, backhanded, or over-and-under.
2647. An alternative way of sticking a SHORT SPLICE. This makes
a splice that is scarcely distinguishable from the ordinary SHORT
SPLICE. It is tucked as in the diagram alongside, which illustrates two
opposing strands. The others are tucked the same way, and after all
are tucked once they are spliced regularly over one and under one
as in ~ 2635 or ~ 2638.
The ordinary OVER-AND-UNDER SHORT SPLICE, tucked once only,
2.641
each way, is often used in the straps of single blocks. Thicker blocks
will require more tucks, so that the length of the splice equals the
thickness of the block. The sharp angle of the shell, at the bosom, 2648
adds to the security of the splice and often the ends are trimmed
short. But on smart ships the straps are wormed and the splices
teased, parceled and served or grafted over.
2648. The RIGGER'S SHORT SPLICE. Opposite strands are half
knotted together and then are tucked over and under once in each
direction, as shown by the arrow in the diagram. The splice belongs
on the strap of a single block. For a double block it would be tucked
twice each way and the ends cut off short.
2649. This is the SAILOR'S BACKHANDED SHORT SPLICE, which is
often confused with the SAILMAKER'S SHORT SPLICE. It is, however,
made with a different technique and has several structural differ-
ences.
After crotching the ropes, the ends are half knotted as in the
RIGGER'S SHORT SPLICE (~2648), and then each of the six strands is
backed once in turn. They are not backed, however, as the sailmaker
backs them (~2632). The sailor backs them in his own way. Each
strand is tucked for'U.'ard over one and under two, instead of over 264~
one tmd lender one, which is the usual sailor's splice. In three-strand
rope this is structurally the same as a sailmaker's backhanded tuck,
and in four-strand rope the splice is not attempted. All six strands
are tucked in turn four times, the three straAds of each end being
kept "a-tier," not "run down" one at a time as the sailmaker does it.
The tucks are taken twice full, once three quarters, once one half and
once one quarter. The splice is put into boltrope and is appreciably
longer than an ordinary SHORT SPLICE.
2650. The sailor enters his fid for the BACKHANDED SPLICE either at
right angles to the rope or else pointed a little to the left. The strand
1
end, which should be whipped, is thrust through end first as shown
by the arrow.
2651. The first mention of SAIL MAKER'S SPLICES is by Kipping
(1847), who says "Left-handed splices are best for roping straight."
He does not describe the "LEFT-HANDED" SPLICE, and earlier works
on sail making give only the OVER-AND-UNDER SPLICE. This illustra- 265""1
tion is given here to show the structural difference between the
SAILMAKER'S SPLICE and the RIGGER'S SPLICE (~2648). The former
is backed once either way, which gives four bights as shown here,
while the latter is half knotted, which gives two bights only. Each
time all the ends are tucked a total of four bights is added.
