Lay out the spars on the ground with the center spar pointing away from the other two.
Begin with a clove hitch or timber hitch at the end of one of the side spars. Then, make six

to eight loose turns around all three spars and finish up with two frapping (binding) turns
between each spar. A clove hitch on the center bar completes the lashing.

Note: The sheer lashing (not illustrated)—which is used to secure parallel spars in bridges

and tables—is simply a two-legged version of the tripod lashing.
