Square Lashing
Square Lashing
Used when lashing two spars or staves together at, or near, right angles to
each other.
A square lashing is started with a clove hitch around the leg, immediately
under where the cross piece is to be. Twist the short, free end of the clove
hitch around the main part of the rope and begin laying the turns as in Fig. i.
When laying the turns, the rope goes on the outside of the previous turn around
the cross piece and on the inside of the previous turn around the leg. Keep the
tope taut. Three or four turns are necessary before you begin the flapping. Fig.
ii.
Make two or three 'flapping' turns between the spars and strain them tightly
as in Fig. iii.
Finish the lashing with a clove hitch around the end of a cross piece as
shown in Fig. iv.
Remember: Start with a clove. wrap it thrice. frap it twice and end with a
clove.
Japanese Square Lashing
Japanese Square Lashing
This is used as an alternative to the square lashing for light spars and
staves.
Fig. 1. Take the middle of the lashing rope round a spar;
Fig.2. Using both ends together (rope doubled) lay 3 turns as in ordinary square lashing;
Fig.3. Take one end across the diagonal and behind the crossed spar;
Fig.4. The other rope now doubles back in front of the vertical spar;
Fig.5. The
ends are now going in opposite directions to make frapping turns;
Fig.6. Finish the lashing with a reef knot across a spar.
Diagonal Lashing
Diagonal Lashing
A diagonal lashing is used to 'spring' two spars together.
This lashing is started with a 'timber hitch' around the two spars at the
point where they cross, so binding them together. Fig. i.
Take three turns around the spars, following the lay of the timber hitch,
making sure that the turns lie beside each other, not on top of one another.
Fig, ii.
Lay three more turns, this time crosswise over the previous turns and strain
to tighten. Make two frapping turns between the two spars, around the lashing
turns. Fig. iii.
Strain the frapping turns tightly and finish the lashing with a clove hitch
around any convenient spar. Fig. iv.
Filipino Diagonal Lashing
Filipino Diagonal Lashing
This is used as an alternative to the usual diagonal lashing for light spars
and staves.
Fig. 1: Start with the middle of the rope and pass the ends through the loop;
Fig. 2: Lay three turns around both spars and then three more turns at right
angles;
Fig. 3: Split the two ends of the rope and make flapping turns between the
spars;
Fig. 4: The two ends, now going in opposite directions, are pulled tight;
Fig.5. Finish off the lashing with a reef knot across one of the spars.
Sheer Lashing
A sheer lashing is used when constructing sheer legs. Start with a clove
hitch around one of the spars then lay the spars together and lash with seven or
eight turns laid side by side. The lashings should be fairly loose to allow
frapping turns to go in between the spars. Make at least two frapping turns and
pull tight. Finish with a clove hitch on the opposite spar you started with.
Another type of sheer lashing is used when you want to lash two spars
together into a long one. When lashing two spars together in this fashion, the
ends of the spars must overlap each other by at least a third of their total
length. Two sheer lashings are used this time, without any frapping turns, at
each end of the overlapping spars. Start with a clove hitch around both spars,
bind tightly with seven or eight turns and finish with another clove hitch.
Sheer Legs
This is one method of lashing three poles together to form a tripod.
Three spars are laid side by side and loosely lashed with a figure of eight
lashing (not a true description). The lashing is started with a clove hitch
around one of the outside spars followed by six or eight loose turns over and
under the other spars. The lashing is finished with frapping turns between each
pair of spars and a final clove hitch.
The three legs are then opened out to form an equilateral triangle at the
base. To complete the tripod, three extra spars should be square lashed across
the butts a foot or so above the base.
Sheer Legs
This is the other method of making sheer legs (favored by most pioneers).
Lay out the spars with the tip of one pointing in one direction, and with the
other two, one at either side, pointing the opposite way. Continue as for the
previous example.
"Gyn" or Tripod Lashing
Conventional
Start with a Clove Hitch on one spar and end with another Clove Hitch on the
spar opposite.
Alternative "Gyn" Lashing
This is exactly the same principle as the Sail-maker's Whipping.
Hold Fasts
Ropes under strain must be anchored securely.
Usually formed from PICKETS; these should be 4 feet long and 3 inches
diameter, driven into the ground:
Log and Picket Holdfasts are for lighter soil. (Takes strain of 12 cwts for
each pair of pickets).
Deadman
Holdfast is a semi permanent anchorage or for stony and sandy soils. Log buried
in ground at depth of not less than 3 feet. Ramp must be dug for hawser
(preferably of wire rope).
3 - 2 - 1 Holdfast will take 2 tons - heavy soil(?).
Natural Holdfasts (trees, etc.) are obviously best. Protect with sacking,
make round turn with separate rope, attach tackle by slipping hook of block
through both loops. If using a strop, used ends should form Larkshead and not
slipped one through the other.
