How To…. Build a Classic Aures Campfire Crane

The final part of the Aures Crane Trilogy – The Classic.

I call this one the Classic as it is the design laid out in the book Camp-Lore and Woodcraft. The author Daniel Beard called it a rustic crane fashioned along similar lines as the iron cranes found commonly over 100 years ago over open fireplaces.

The crane is named after Victor Aures, a Scout Master from Buffalo, NY. I found a good article on this from an issue of the Boy’s Life from 1915.

The Classic Aures Campfire Crane

You do not see the classic crane often since it requires a specific configuration of angles on the forks and it’s all too easy to cut through the thin layer of bark and sap wood needed to form the loop on one end.

Measuring

I stumbled upon a good piece of hazel recently with a strong main fork and the necessary secondary fork at right angles to the main one.

The basic parts & measuring up

I had a good pole that I was going to use as the upright and measured the top limb for trimming. I estimated with my eye the amount of wood I would need on the top limb to form the loop (I call this section the tail before it is formed into a loop).

Trimming the excess

Trimming

After sawing off the excess I started the slow process of removing all the excess wood on the tail. It is easy to remove the wood at first but try and remove it evenly as you work.

I tend to work from the end of the tail and work up the crane towards the fork. This helps in reducing the chance of chunking through the wood and destroying the crane.

In the pictures below I have worked my way down to the pith and then just passed it. I forced myself at this stage to take my time and work methodically.

Important to trim evenly from bottom to top

Eventually I could make the wood bend slightly (it was only a couple of centimetres wide now). I scared myself when the bark cracked but that is OK – it is the sapwood that needs to bend.

When bending down the wood do it slowly and do not try and force it.

Trimming and flexing

I finally had just a thin piece of sap wood left that could be bent a bit more but not fully. To help this process along I used the tip area of my knife to cut out some more of the wood without making it any thinner than a couple of centimetres.

To help the bending process I left the crane in a stream to soak up some water. If you have the tools to steam bend wood the job would be much easier.

Last few scrapes and softening

Once the tail was very pliable I flattened an area where the tail would be whipped to the crane then marked the tail and the main body of the crane with a pencil so that I retained the size of loop I wanted while I whipped it.

Whipping

In the book Camp-Lore and Woodcraft, Beard’s drawing shows the tail being tied off with strips of bark. I will use bark when the crane has fully seasoned (it will shrink in the process) but for now I whipped it with some old paracord. I whipped it twice with different cord as that is what I had to hand.

Whipping the wrap

The loop should be big enough for your upright and positioned so that when the crane is hung on it and braced on the fork, the pot arm is level and pointing slightly upwards.

Hangs well

The Pot Arm

I then went to work on the pot arm, carving out little notches so that I could adjust the position of the pot easily along its length.

I also put my usual dimple on the end for hanging another adjustable pot hanger off it.

I took the crane out on a Bushcraft course with the Royal Marine’s Cadets and it was soon in action.

It is very easy to move the crane up and down with light pots (I advise removing heavy a pot from the crane before adjusting the height then replacing it).

The crane also swings easily away from the fire. If you do not trust the loop to hold a heavy pot, you can back it up with a loop of cord.

The Three

I really enjoyed making these three Aures Cranes and hope to see a few more over fires at Bushcraft meets in the future.

That is it for me on the Aures Crane (I am sure you can come up with some more variations on this), however in the course of my research I discovered a Single Pole Crane – that is next on the list.

How To…. Build a Double French Windlass Cooking Rig

A few years ago at the BCUK Bushmoot in South Wales I ran a class looking at different campfire cooking set ups. As well as showing the students my set ups I had asked them to bring along examples of their own if they could. One that caught my eye was from my friend Steve Mesquite Harrall. It consisted of two forked uprights and a top bar that could be turned to raise or lower a pot that was suspended beneath it on a piece of string.

Steve had learned this from Wayland of Ravenlore Bushcraft and there is a good picture of the set up on Wayland’s Ravenlore site – Hang up your Billy. Wayland told me he’d got the idea from a book by the French adventurer Nicolas Vanier called ‘North’. The rig did not have a name and it was Wayland who used the term French Windlass (Windlass meaning to ‘haul or lift’). I have just added the ‘Double’ so I can cook with more than one pot.

I really liked this rig when I first saw it but soon felt the need to be able to adjust the height of more than one pot at a time. You do not easily find two decent poles with a double fork in the right place to do this so I had to come up with another idea. The solution in the end was so simple that I had to laugh at my own stupidity for not thinking of it quicker – just make a new fork by splitting the pole above the natural fork.

Double French Windlass Cooking Rig

The basic parts I used were one small piece of wood to make a pile driver (I’ve heard this called an El Salvadorean pile driver) to create holes for the uprights, two forked uprights and two poles to act as spars.

I trimmed a point on the piece I was going to turn into my pile driver first. I used a small round of wood to act as a work surface and kept my axe work to the far side of the round for safety.

The basic parts and the start of the El Salvadorean pile driver

Once the point was finished I put a chamfer on the top of the pile driver by cutting out little pieces of wood all around it. Doing this helps stop the pile driver from splitting as you hammer it into the ground to create your hole.

Carving the pile driver

As the pieces I picked for the uprights were fairly thick I had plenty of wood to split to create my second fork. You need to ensure that the split you create is on the same plane as the natural fork.

To batton safely, make sure the bottom of the upright is secure and hold the axe so that the blade is at right angles to your body. I used the pile driver as a batton to create the split. Once the split reached the level of the natural fork I stopped.

Battoning out the second fork

To stop the split going any further I whipped some twine around the upright at the base of the split. To keep the fork open you will need to add a wedge and the whipping will stop the split travelling down the upright when it is inserted.

A little whipping

I took one of the spars and carved a triangular end to it – the thin end of this will be the wedge to hold open the split in which the spar will sit.

Carving the wedge

I used the pile driver to batton the wedge down into the new fork until it reached the whipping. Then it was a case of just trimming the wedge to finish.

Inserting and trimming the wedge

I felt that my fork needed to be a little bit wider still so with my knife I cut out some wood from inside the fork. Once that was done it was a case of giving the upright a pointed end and trimming off any knobbly/sharp pieces from it.

Widening the fork, pointing and trimming

The second upright was produced in the exact same manner and they were soon both ready to go.

Finished uprights

The rig works on the principle that the weight of the pot locks the spar into the forks on the uprights. To make this work you need to carve triangular-shaped ends to your spars (Wayland likens this to a prism shape on his blog). I ensured that the points of the triangles at each end of the spars matched up with each other. Take your time with this and before each cut ensure they are lined up.

Carved triangular shaped ends on both spars

The ground where I was testing this out was at the back of our garden in an area that was about to be weeded and planted so it was a little soft but even so if I had just hammered the upright into the ground it would have split the top fork. The pile driver came into its own here as I was able to really hammer it into the ground (try and make your pile driver slightly smaller in diameter to the upright to get a snug fit) and create a hole for the upright.

Use the pile driver to create a hole for the first upright

Once the first upright was in I gauged the distance to where I needed to put the other upright in using one of the spars and repeated the process starting with the pile driver and then gently tapping in the upright.

Gently tap in the first upright and repeat the process for the second upright

Check your alignment is correct by lining up the forks and place both spars into their forks. I tested the spars were locked in place by trying to turn them gently. No need to force them as the weight of your pots will lock them down further.

I took this shot to show you how the spars fit into the forks. All very basic but works surprisingly well.

Locked in

To suspend the pots I used some old string and tied it on with a clove hitch  and then a couple of overhand knots to finish. I did not make them overly tight because I wanted to be able to release them easily  to re-position them. Once that was done I attached the hooks. Use whatever knots you are comfortable with but make sure they and your string will hold the weight of your pots when full.

If you are worried that the string will burn then dampen it with some water (avoid string that will melt easily). I have never had the string burn through as when I am cooking I do not let flames grow big enough to go near it. Also when starting your fire ensure that the spars are not in place so that the initial flames do not burn the string.

Once you are cooking it is very easy to lift and rotate one of the spars to raise or lower a pot by winding or unwinding the string. As we were boiling some water in the Dutch oven I got my daughter to help me but if the pot is light enough then you can do this easily by yourself.

To adjust the height lift the spar and turn it a few times

I also use another style of pot hook quite often (I learnt this from one of Ray Mears’s videos) which involves the use of a lark’s foot knot. All you need is a small loop of string that is able to go around the spar and through itself to leave a smaller loop to insert a traditional adjustable pot hook. To raise the pot all you need to do is loosen the lark’s foot and re-position it on another hook.

This is the set up from various angles so you can see how all works in more detail.

I am glad I finished this little project as it has been on my list of things to do for a while now. It is a great set up that does not take long to do and it’s an easy way to cook foods that requires different temperatures at different stages.
