Cam thumb loop repair and sling replacement questions.

I recent bought a yellow alien that's had some prior use; it's fine mechanically but the rubber/plastic that covers the thumb loop has seen better days, and the sling is pretty tattered. Here's a picture of it:



I can push the plastic back together and it covers the cable fine, so I was wondering if I could just tape it up with electric tape or duct tape or some such thing. Is that good enough or not safe? Is there a better way to do it that isn't expensive/a pain in the ass?

As for the sling, I've seen other people who have replaced their sling with webbing; that's fine but I was wondering if I could use some 8mm perlon chord or something similar. Just trying to work with what I already have and not have to send it out for a new sling. I may do that eventually, but right now I'm trying to save cash.

Thanks in advance for any advice. I can also take some more photos if necessary. Cheers!

Thanks for the link Max, pretty informative. I wasn't thinking about using dyneema/spectra to resling it, more along the lines of regular nylon tubular webbing.

tie a water knot and then back up the tails by sewing them heavily with regular thread, that way it can't come untied and kill you.

Yeah seriously. Just wanted to check if people had any tips. It's definitely gonna end up jerry-rigged.

wrap it in electricians tape or something, or just use it for aid. that's probably the safest short of throwing it away.

The (urethane, I think?) tubing is obviously toast. Bare cable + spectra webbing = quick failure.

If you really want this cam to be usable, reliable, and not prone to catastrophic failure, try and find an old thumbloop from a 1st generation Camalot Junior. And then tie a new sling around this...

Just use a carabiner or quick draw, like an old school camalot

that was my first thought. Nuts have bare cables.

I have a gold alien with similar situation I just paid $70 for from a guy on MP. The cut is not all the way down to cable though. Is there anyone out there that can replace the plastic/urethane around the thumbloop without undoing swage?

if you want to fix the cable tube...you could try getting some tubing at home depot and replace it....slice it in half, place on cable, then heat the two ends back together cover in tape.

I will give that a shot. Thanks.

you also might try some plasti-dip you could just cut off the old cover and dip it in the plasti-dip bada-bing I think it'd be more durable and better than using heat shrink tubing.

Plasti dip? I might just give it a shot. I just put a lighter to the small cut at the base of the thumbloop and melted it closed. Maybe I can just plast dip the old plastic to seal it up. Then tape it up.?

I appreciate all the help. I guess I can hit Home Depot up tomorrow and look for tubing and plasti dip. I don't imagine it's possible to put the tubing on like the original. Too bad. Next time I will ask for pics though I guess it may have happened while being shipped as the seller said, "I never saw a cut". Thanks to all and still open to any new ideas.

If you don't care for a biner, you could always put a short sling with a rated Petzl Mallion on there. IME plastidip is softer than the nylon tubing used on Aliens. That said, the BD folded-over sling thing is because their wires are thinner than usual and the extra layer prevents the wire from cutting the sling. Also of note is there are a couple off-brands I recall seeing that have what looks to be loops simply with plastidip between the wire and sling. ANDE brand, possibly out of Italy? Got a couple in the gear box and can dig them out if needed.

But as for replacing the tube without undoing the swage? Not likely. Lots of bending in the loop when loaded, which means any cut&glue solution is likely out, and tape brings up the whole what's-in-the-adhesive-and-it's-effect-on-the-sling question. Hate to say it, but you should retire it. IME the tube splits like that when heavily loaded (6 or 7 kN) and is probably due for retirement. Do the lobes have flat spots?

He said that?

That sort of damage comes from loading the piece. It didn't happen in shipping. I'd ask for at least half your money back.

Exactly. Any shipping damage would be on the outside of the loop, not on the inside. That cam was definitely loaded.

How about a quicklink on there? That way, you don't get confused when re-racking & taking the biner off. Just pop a QL on, screw it shut & go for it?

The lobes have seen some use. They are a bit flat around area that touches rock when cammed. My guess is somebody whipped on it pretty hard;) Does anyone think Fixe will be making any larger sizes in the future?

This is first time I've been burned on MP. Live and learn! Thanks Aric and everyone else.A bit off topic but I have an alien dated 12/05 without the dimple of death. Who should I go to for a pull test?
