A few years ago I, er… a friend of mine, put up a rope swing in a nearby park. It's in a large eucalyptus, about 25 metres high, and is much loved by many local kids – and parents.
Originaly I just used super cheap polypropylene rope (I think it was polypropylene, it was that cheap, hard, twisted stuff sold in hardware stores for general utility) with an eye splice forming a slip-knot around the branch. The splice has held up well, but the rope started to deteriorate to the point where it is fraying, so I had to cut it down.
Since then I've been seeing kids and parents turn up to the "swing tree", look up at the cut-off end of the rope and walk away in disappointment. And it's Summer holiday time here, so I need to replace it.
So, can anyone recommend what sort for rope I should use? Selection criteria are:
- Durability - It's out in the weather all day long, Winter (mild, never freezes) and Summer (can be blazing hot)
- Enough strength to support an adult swinging from it; and lastly,
- affordability - While it doesn't have to be super cheap, it could get cut down by the council or some grump (I did have a problem with it getting cut off at head height by some unknown person for a while, there's a few grumpy old Boo Radleys around), so I'm not going to use proper climbing rope or anything.
Also, any suggestions for better ways to attach it to the branch would be good. I'm thinking this time of having a stopper knot below the loop, so that it doesn't cinch on the branch, and maybe adding a sleeve of some flexible tubing to avoid rubbing on the tree.
