Vectran webbing tree straps.
Ive just stitched up my first pair of tree straps from high strength 25 mm/ 1" polyester sheathed Vectran core webbing.
The 1 metre strap weighs 27g and the 1.5 metre weighs 41g. There are lighter tree straps, but none this strength/durabilty to weight ratio.
The breaking strain on the webbing is 2200 kg, way more than needed but they should last forever. They have no stretch at all. The webbing is quite hard to cut with scissors too.
I reckon they could serve double use as tow ropes
Thanks to Albert Skye and his tree strap article on how to maximise the stitching strength, and Ikemouser's post on dyneema tree straps which spurred me on to source some high performance webbing.
Any comments/criticisms are welcome.
How much was the material to make these?
where from turn? I'm in the UK.
Update on straps;
7 Nights hanging on these straps have left me impressed with them.
There is no stretch at all-the height I hang my hammock initially is where it sits permanently. With dyneema whoopie slings and these straps, sitting in the hammock feels akin to sitting on a brick wall-there is no give at all.
I was careful to sit down slowly to avoid much dynamic loading.
The stitching shows no sign of stress-I must have done a reasonable job on it
I'm intrigued by your stitching.
From the pic it looks like there are MANY rows of stitching VIRTUALLY covering the material where it connects.
Does this amount of stitching weaken the project?
There are so many perforations to the material that the grabbing on is lessened.
Is my thinking wrong?
My stitching may not be optiimal-I was guided by Albert Skye's post on tree huggers and stitching webbing, but may have got the wrong end of the stick.
Saying that, the vectran core that delivers the strength is not webbing-its paralell fibres-like dyneema core rope..
I used a ball point needle to avoid cutting the vectran, and as its cut resistant, I didn't think many stitches would weaken it to a great degree. The number of stitches were calculated by the webbings b/s divided by the b/s of the polyester thread, plus 10% safety margin.
My Q was not a criticism,,,,just a q...
the job looks marvelous and the results speak for themselves../
Just the first time I'm seeing this sewing method...
Very cool and the weight sounds pretty awesome. Wonder where I could pick some of these things up in the US.
