In our blockading guide we cover many ways of defending territory. This page goes into more detail about setting up scaffolds which can be used to effectively block roads or small throughways such as factory entrances.
For your basic Tripod, acquire: 3 scaff-poles, about 25 feet long
2 swivelling scaff-clips
Rope (cheap blue poly-prop available from the local hardware shop is fine)Spanner to tighten scaff clip
A Spanner is needed for the nuts on the clips. You also need a fairly large (high if indoors) space for fixing them, experimenting and practising.
It's tricky to get the clips fitted on so that the poles can be held parallel (for carrying etc.) and at the same time be in the right position to erect as a tripod.
The main assembly is formed by securing two poles in an 'A' Shape and using a third to prop the two up.
The securing clip for the third pole has to be about a foot below the 'A ' shape clip, this allows the main poles to close over it in the folded position.
This clip should be mounted at roughly 120 degrees in relation to the main clip in order to swivel open correctly.
With a little experimentation you will find where to place the clips so that the poles lie parallel for transport yet are easily opened into a tripod.
You will probably need at least 5 people to erect a tripod made with steel poles:
At least one strong person to lift each of the two main legs by walking down beneath it from apex to base;
one person to do the same with the third leg and at a crucial moment, to swing this leg out and to prop up the 'A';
and one person with their foot braced against the base of each main pole to stop it skidding forward.
With aluminium poles the job is easier, demanding only 3 people.
Once the tripod is erected, at least one person must shin up the pole at the speed of light in order to be out of reach at the top.
A simple circumference rope tying the poles together about three feet from the top can be fixed prior to erection if desired and used to take the weight of up to three people.
A simple hammock sling is more comfortable and stylish. It's made out of a length of strong light material, such as rip stop nylon, knotted at either end, with the two ends of a short rope tied securely just inside these knots. The rope can be slung over your shoulders as you shin up the poles, and when you reach the top simply slipped over the poles making your stay much more comfortable.
For extra stability and a convivial number at the top, three short horizontal poles with clips can be used as braces. Leave each short pole dangling from one of its clips until the tripod is up, then do up the second clip.
Before climbing remember to take the spanner - you may not have a second chance to get up with it.
A climbing harness and slings make this job easier.
This augmented tripod will be heavier and may require a greater number of people to lift it.
A tripod lacking these bars can be stabilised using a circumference rope linking the legs a couple of feet above the ground. This will secure against collapse due to accidental slippage, but not against attack. Car exhaust clips are useful to stop the ropes riding up.
