2102. Shear leg lashing is much like seizing, but is on a much larger

scale. Start with a CLOVE HITCH around one leg, then pass a series 01

round turns, eight or nine, rather loosely. Put them on just tightly

enough so that the several frapping turns which are to be added will

heave the round turns closely together between the two legs. The

lashing is finished off with a CLOVE HITCH around the second leg.

Nail cheeks to the posts when practicable.

2103. A pole or post for a scaffolding. A tall pole is built up with

a series of parallel poles. The joints are evenly staggered. The bigger

2'02. 2.101- firs are at the bottom of the pole and the butt of an upper fir rests

on the head of a lower one. There is a lashing above and below each

joint, consisting of four to eight turns. These are first made hand

taut and then are hove taut with a marlingspike. After this they are

wedged, the wedge always being driven downward from above.

turns. Several frapping turns are added with the two ends, which are

then reef knotted together. When the shears are opened the lashing

• one of the rope ends being expended in each interval. These crossing

lOS- 101 turns may be finished off with any of the three knots shown in the

previous chapter at the bottom of page 327. In the tripod shown

here the center leg is lashed in a direction opposite the two side legs.

When the tripod is erected the feet may have to be made fast to

each other to prevent spreading.

2."0 2106. A good way to pass pole lashings (jfi 2103) is to tie as pic-

tured here, and then tighten one turn at a time with a marlingspike.

This is discussed as KNOT jfi 1240.

2107. A lashing that is passed the same as jfi 2105 but the odd leg

is laid parallel with the other two instead of opposite. If the lashing

is made too taut it will be necessary to stake out the feet.

2108. To support the tackle of a shears take a round turn with

a heavy strap as pictured, and hook the tackle to this.

2109. Frapping turns in a lashing are similar to the crossing turns

in a seizing. Around large spars frapping turns give great leverage

and often provide all the power that is necessary to tighten the lash-

2110. A shears requires the support of a single guy which may be

led to a mast, a tree, or a distant stake. If led to a stake, the guy is

sometimes braced with a pole in the manner that a clothes pole is

~'ll elevated. If erected on deck, the feet of the shears will require nailed

cleats to prevent shifting.

2111. To suspend a tackle block under a tripod, put a BALE SLING

HITCH over the top of the pols of the center leg and w~Jc it well

down on the pole.
