Roy: Your 19 year old solid stem Friends may themselves be worn out, forgetting about their slings. Just like a few of mine. The axles get worn and weakened, apparently. Your harness sounds rather - alpine. :)
Maybe we should have big ST parties at climbing test labs - BD, Trango, Fish, etc. Those who live nearby can bring a bunch of old stuff, and maybe some food and beer, and a sober technician can bust it all while we hoot and holler. Maybe some dogs and stuff, too. (Ron can bring his arsenal, and Junior.) I bet we'd learn a lot, not all of it amusing.
Russ, I got this old "Fish" wall swami, with some wear, I know you probably dont want everyone sending there old harnesses to you, but its yours so maybe some more interest. The belay loop is worn, and its about 10 years old and has done 11 walls. If interested I'll send it your way.
As for the belay back up on the leg loop, well essentially that back up is holding the brake strand into the breaked position so it probably is'nt holding that much weight, most of the weight and holding power is still at your belay device on your loop, the back up is really just a third hand to hold the break strand. Do you fell like your holding 300lb. when you rap? If your belay loop actually fails then well I guess its not much of a back up, but provided your loop is in good condition as well as your rap device than your leg loop should be fine.
If you are super worried about that, put your back up right on your belay loop and above your rap device. This however is then relying on the strength of your back up material since in an accident all your weight will be on that material. This is nice if you have to re-ascend the line for some reason.
Good point. However, there are some times when that backup could be loaded with more than 800 pounds. Those are circumstances where it would not be playing the role of just "backup break hand".
Examples would be:
Your belay loop breaks (highly unlikely)
You threaded only one strand of rope thru your biner when loading your ATC (possible)
You come unclipped from your belay device. (how on earth...)
Your belay device/biner breaks (incredibly unlikely, but has happened with fig 8 belay devices, if I remember properly)
Anyway, its possible, though it seems like in most cases it would be just a "backup break hand."
I have a first run, original model #2 freind (~78?) with it's cherry (tied) sling. I have fallen on it within the last calendar year, to no negative effect. Yeah, there was something newer backing it up.
I had assumed newer cordage would make it bomber, thoughts? In a way, I'd like to see how it would test out. But it's my oldest freind and I don't really want to wreck history.
Might trade slightly newer stuff ( I have I have 6 original 2,5's for example) to a testor, for brand new cams.
that's just the age of the slings and was mussy's color code upgrade proj suggestion that afternoon.
Some of those cams, well...
I got 'em from that Abalakov guy summer' of '64, (when I was in nursery school yah)
...Way before he showed the idea to Jello.
