SHEER LASHING-

SHEER LASHING-

or sheer legs, where the spars are opened to form an inverted ‘V’.

Line up the ends of the spars

• Start with a timber hitch or clove hitch round one spar
• Continue with 8 to 10 turns round both spars – these turns should be neat and firm but not too tight.
• Do three frapping turns and finish with a clove hitch on the second spar  (a) and (b).

The lashing tightens as the sheer legs are opened which is why the first turns round the spars should not be too tight or it will not be possible to open the legs as required  (C).

Introduction

A sheer lashing is often sued to bind adjacent poles together. It is also a good way to reinforce a broken or weak pole. The frapping turns used to tighten the lashing may be omitted and replaced with wedges inserted between the poles.

A loose Sheer Lashing made around the ends of two poles will allow the poles to be opened out and used as an A-frame. It can also be used to form a tripod just like the Figure-of-eight lashing.

Step by Step Guide

• Lay out the poles. For most lashings you will want to lay the poles side by side with the butt ends aligned (thicker ends).
• Tie a clove hitch around one of the outside poles and secure the standing part by wrapping it around the running part (or trap it under the first turns).
• Note: If you only lashing two poles together or are using the lashing to ‘extend’ a pole it may be better to simply tie the clove hitch around both poles and pull tight. Be sure to leave a long end on the Clove Hitch for the last step.
• Pass the rope around the poles to form a first turn.
• Pulling each turn tight made a series of turns until the lashing is at least as long as the combined diameters of the two poles (usually a set of 4 to 6 turns will be sufficient).
• Tighten the lashing with a frapping turn by taking the rope down between two poles at one end of the turns. This should be difficult to do if the turns have been pulled tightly (as they should be). Bring the rope back up between the poles at the other end of the lashing and pull tight. Repeat 2 or 3 times.
• Start the second set of frapping turns by taking the rope around the centre pole and frapping. Take the second set of frapping turns in the opposite direction to the first set.
• Repeat for any additional poles.
• Pass the rope once more between the poles then around one pole and tuck it under itself to form a half hitch. Pull this tight and make a second half hitch forming a clove hitch by taking the rope around the same pole and tucking it under itself.
• Once the final Clove Hitch is tied be sure to leave a ‘long end’.
