Re-slinging cams... gear nerd question

Postby mspeverill » Wed May 04, 2011 11:53 am

So... re-slinging cams with techcord. Triple fishermens... to avoid having a big clunky loop, I tied the triple fishermens around the other portion of the loop. Now it's less clunky and a looks more like a dog bone.

will this result in certain death for the user? should I stick to the normal tri-fish with a loop? any better advice on how to re-sling other then send them away and pay lots of money?

Ouff ya I agree with Choss if you want us to understand you'll need to post a pic.

I use webbing with a water knot one of my old manky cam.

If i was to change all the slings on all of my cams I would definitely get them re-slung.
5$ a cam is not a lot of money considering how much of a b*tch it would be to have slings with knots. Ragged mountain in North Conway offers this service. Most cam manufacturers will also offer a re-slinging service.

Also I don't know what kind of cams you have, but some cams with thumb loops must use larger style webbing because using smaller dyneema and cordelette would pinch the thumb loop.

Here is a link to it

a normal triple fishermans gives you a loop

they ran a portion of the loop through the fishermans

so now instead of an O, they have something like a dogbone on a draw - like the shape of an 8 or an hour glass

don't know the strength variability though

Plenty strong. I bet the axle would fail before the techcord.

It may depend on the type of stem/sling attachment. Wire looped stems generally have a double layer to prevent the wire from slicing through in high loads. See Dom's link.

I'm picturing Roger's old style camalot stems when I said techcord is appropriate like this one:

I've seen the DMM tests on mastercam-style thumb loops where thin cord cuts through the wire as a mode of failure. I'll agree that wider webbing is a better choice for reslinging cams with thumb loops like these ones:

Ditto Dom's post. Cut to the chase and get them professionally re-slung. Had some of mine done at Ragged in North Conway and they did a good job and you can choose whatever length sling you want. $5 a cam. Tech cord will cost prob at least half of that. Do read the article on the BD website...worth a read.
Safety third!!!
