cam slinging

Recommended Posts

why do you all discuss having cams re-sling by various gear shops or by the manufacturer? couldn't you just tie slings through the cams yourself?

you could tie them yourself, but many people don't like a bulky knot on there.

They're discussing sewn slings (Spectra or Dyneema typically).

(for the sake of newbs) tieing spectra or dyneema is a very bad thing. the material is slippery and will not hold the knot. using nylon webbing just isn't as strong. Besides, knots lower the breaking strength anyway.

Best to do it the right way.

Let's not inadvertantly cause concern through a misunderstanding. Nylon is not as strong as SpectraDyneema. Knots do reduce the strength of the rope/sling/whatever.

 

Now for the key statement: Nylon when knotted properly is plenty strong for climbing.

 

The main reason you wouldn't want to tie your own cam slings is the bulky knot and the tendency of knots to come untied. If you don't mind the bulk or checking the knot frequently, you should be fine.

Quite correct, thanks for the clarity.

This applies to NYLON ONLY. You should never knot spectra or dyneema. But, since I've never personally tested this theory, maybe someone braver than me should try it! hellno3d.gif

I've heard that you can knot thin (mammut 8mm) spectra using a 2x fishermans, but im not about to start cutting up mine to try it. anyone done this?

A well tied beer knot in nylon is fairly low profile, and nearly as strong as a sewn sling. Beer is good. bigdrink.gif

you'd want to make that a triple fisherman's for spectra / dyneema, I think.
