Diagonal lashing

Diagonal lashing is a type of lashing used to bind spars together. It is usually applied to cross-bracing, but may by used on any poles that cross each other at a °45° to 90° angle, and poles that do not initially touch. Large structures may be built with a combination of square lashing and diagonal lashing.

Bailing twine has sufficient strength for most lashing applications and rope may be used for joining larger poles.

Diagonal lashing steps (see image at right);

1. Begin with a timber hitch
2. Make three turns in each direction.
3. Make two frapping turns, tightening the joint as much a possible.
4. Make two half hitches
5. Cinch the half hitches into a clove hitch

A lashing stick can be used to safely tighten the joint.
