Deadfall Deflector Print E-mail
Written by BOD   
As we all know deadfall can be deadly and is a real hazard in forests. Some years ago a large branch about 30 feet long and as thick as a man’s body fell on a friend of mine breaking his spine and knocking him out. He is now a paraplegic. I have had medium stuff fall near me a few times and had a small 18 inch long stick land on my head a few days ago which was painful but not injurious.

For some time I have been putting up what I half-jokingly call my “Deadfall deflector”.

This is a 5-7mm braided nylon utility line which goes over and around the area my hammock is strung up. It starts with a slip knot (falconer’s or Buntline) then is clove hitched or otherwise hitched around each succeeding tree and then tensioned off. The larger rope diameter makes it easier to undo later. The line is useful for other things as well and I have used it for river crossings and once for a classic abseil down a short steep stretch. Usually I use the 7mm line.

The diagram shows a bird’s eye view set up for a Hennessey.

deadfalldeflector.jpgThe trees available vary and you can arrange it anyway you like depending on tree availability and which are the “at risk” sides. The invariable is the line over and parallel to the hammock ridge line (which I some times double).

Some people are amused by it and some say it is a blot on the wilderness as I clip, tie or drape shirts, trousers, bags, water bottles knives etc off it. However, I find it convenient as it keeps stuff off the ground and easily accessible.

But does it work? I’ve always wondered. I found out a few days ago.

I had tied my hammock onto 2 healthy looking 15 –18 foot saplings 4 inches or so in diameter. Unknown to me the interior of one had been damaged and only an inch of good wood remained.. During the night I heard a crack and knew I was in trouble somehow. The hammock started to fall and I expected the usual painful winding thump I associate with structural failure in the cheap hammocks I’ve used in the past.

Surprisingly, I landed on the ground, unwinded and quite gently. After negotiating a pitch black slow exit so as not to damage the hammock I inspected the scene. The tree at the foot end had fallen straight in my direction, as one would expect, but had been caught by one of the cross lines which, being nylon, had good stretch. The tree came to a halt at about 40 degrees. I definitely would have hurt if it had landed on the hammock and me. A real RoadRunner - Wile E. Coyote scene.

Sure, this system won’t stop a 50 metre tree or an enormous limb like that which crippled my friend, or help with a branch that falls like a spear into me, but it is now proven as far as I am concerned. And it may slow down the momentum of some stuff enough to lessen the extent of your injuries. It could be deployed over a dome tent quite easily too. In this case I was using the 5mm line

I wonder what sort of systems you use and your experiences with deadfall. This could be useful to those members new to camping outdoors.

do you have any photographs of this? I'd be interested to see it!

thumb_bushmoot20071.jpgBushMoot, the best event of the year - from 1st -5th August 2008 at Merthyr Mawr in South Wales. 

The Moot is now Full

Tickets for the full event have sold out, sorry if you've missed the opportunity but there will be plenty more Moots in the future.  We want it to be a great experience for everyone which means keeping the numbers limited.

Day visitors are more than welcome but we're no longer taking bookings through the shop so you'll have to sign in and pay at the event.  The day rate for the event is £20 payable at reception - Camping spaces are no longer available.

Fish Trap (01.04.2008)
thumb_fishtrap9.jpgI used Hazel wood. Choose the thin long shoots of wood which i would think are a couple of years old. If you don't catch anything at first don't worry. It may just be a case of changing a few things.
Birch Tar - How to collect it (23.02.2008)

Wild Wine (Part 8) (28.11.2007)
thumb_wildwine6.jpgNow we could bung a label on (which should always say they type of wine and when it was bottled). I suggest you cross-reference to a book of recipes and notes so that when you get a cracking wine you can recreate it. We are going to add a little something to the presentation of the wine by putting a foil cap over the neck. First we drop a foil cap (available for a couple of pence from a wine shop) over the bottle neck.
Wild Wine (Part 7) (26.11.2007)
thumb_wildwine1.jpgRight, we now have clean, fined and filtered wine. We pour it into clean (yes and sterilised) bottles with a funnel. We need to cork it. Its possible to put corks in with a mallet. I use a corking gun and waxed corks that do not need to be soaked (plain corks do)

thumb_wildwine1.jpgWell, the finings have worked – the wine is beautifully clear.

Paracord Bracelet Tutorial (23.04.2007)
thumb_paracordbracelet16.jpgAs soon as I'd finished my Paracord Bracelet, I'd decided to write a tutorial on making one. A good thing considering the majority of the responses since I posted it were asking me how to do it! Here goes.. You will need approximately 3 metres of paracord with the ends already sealed/melted, and something to make a temporary knot - a twist tie or piece of string should suffice.

How to Sharpen an Axe (09.07.2007)
thumb_axesharpening21.jpgI have been asked a number of times recently to provide some advice of guidance on the best way to sharpen an axe. Whilst I am always happy to provide input, I thought that it might be worthwhile to put together a tutorial on the basic techniques. The techniques used in here are intended to provide not only a sharp axe but also a safe and efficient axe.

Fire By Friction - Using a fire-kit made with stone tools (31.05.2007)
thumb_firefrictionwhitcombe2.jpgThe whole kit took less than three hours to finally pull together — though that really overlooks by far the most time-consuming aspect, the preparation of materials. In fact, preparation has two components, actually. The first is the selection of materials. The second is the actual preparation.
