In my last pioneering project we built a simple swing
In this instructable we're going to use exactly the same knots, numbers of poles and methods to build a monkey bridge. Like the last one we're using the same tree and concreted metal fence posts to anchor. You could use three-two-ones however to anchor it down.
You will need:
Six poles (3.5+) in length
Rope - we used numerous lengths:
- 6x6 foot lengths for lashings.
- 3x loooonnnngggg lengths for the handrails and one thick bit for walking on
- lots of small 2.5-3ft lengths to join the foot rail to the hand rails.
Step 1: Prototyping
Step 2: Laying out the A-Frames & lashing
Step 3: Roping the hand holds and footrail
Hand holds are loosely tied to the top of the a-frames using something simple like a cloves hitch. These can be tightened later, especially if you have a handy ladder.
The foot rope just lays on the a-frame. This has to be very tight so it's the last to be lashed.
Step 4: Tightening up and A-frame position
It's important to make sure that the a-frames are at an angle leaning towards your anchors. When we stress the foot rope this'll pull them up, but they shouldn't be totally vertical as seen below.
The foot rope has to be tight. When you step on it, it's going to sag, so you need it VERY tight.
Step 5: Joining up footrope to handrails
Step 6: Enjoy!
We sent our lot up in order of approximate weight so the foot rope wasn't too stretched which will happen the more people use it. You can keep tightening it up, just make sure you don't release it when someones on it ;0)
