This is a post that came about because someone decided to chop down a tree. On a recent Sea Cadet training weekend we ended up with one instructor (Jess), one hammock and one tree – my friend Dave and myself had bagged the other trees for our hammocks :-). Not an ideal situation for Jess you could say.
We could not camp elsewhere and there was nothing in the way of available natural material to help us (we were on a military camp). Thankfully my friends Alan and Dave spotted some old poles (used for team building exercises) at the back of of a building. So Dave with Jess as his assistant in true Seacadet style, set out to apply their seamanship talents to our problem.
The Shear Lashing
They collected some assorted pieces of rope and a couple of cadets to help out. The poles were quite long and thick so they decided to tie the poles together about two thirds of the way along their length. The poles were tied together using a shear lashing (I will be using Grog’s Knots to help describe how they did this).
To start the shear lashing they attached the rope to one pole using a timber hitch and then wrapped the rope a number of times around both poles (this is known as wrapping). To make this easier the poles were raised slightly of the ground and the cadets helped to pass the masses of ropes around the poles.
Once the wrappings were completed the lashing was tightened by being frapped (nothing to do with Facebook). Frapping is the nautical term to describe the tightening of a rope or cable. Dave did this by completing a number of turns around the centre of the lashing and pulling it all in tight.
To finish the lashing off he secured it with a clove hitch to the pole without the timber hitch. There was plenty of rope left over as well to help with anchoring the shear legs down.
Though the poles were large they were surprisingly light so they were soon standing vertical. A spare piece of rigging line was looped over the pole with the timber hitch on it and with the spare rope from the shear lashing the legs were securely anchored by wrapping both ropes around base of a solid fence post.
Both ropes were then tied off around the shear lashing on the poles to make it all secure.
If you do not have a handy anchor like our fence post you can make your own. In the past I have had shear legs and tripods for hammocks anchored safely with three large wooden stakes.
If you cannot drive your shear legs into the ground I would advise you to tie them together near the bottom so that they do not inadvertently splay out. Dave used the last of the lashing rope (it was a rather long piece of old climbing rope) to do this.
Finally, to finish the set up the shear legs were tied securely to our single tree using a top line. This top line as well as securing the shear legs was to act as a line to hang Jess’s tarp off.
Testing & Set Up
I did a bit of testing after we had hung the hammock. I figured if it took my weight then Jess would have no problems. The top line went slightly slack when the system took my weight so that was re-tightened while I was in the hammock.
After that it was a simple case of rigging the tarp and Jess setting up home for the night.
This was a great solution from Dave to our missing tree problem and took less than an hour to complete. Jess slept the whole night soundly in her impromptu sleep system and I was chuffed that I managed to capture most of the stages in its construction.
