My point exactly - Everyone should lob onto their gear regularly just to remind yourself . . .

We do it quite often - even on a DogFace though it's more like Russian Roullette there - the piece(s)
either hold and you feel a nice false sense of security or it blows and you realise you are ok . .

The weirdest times are contemplating jumping on dubious gear - the logic being that you must trust it if
you placed it - the reality though is that it is your last hope and you don't want to roll the dice . . .

On standard rock with good gear it should be easy and a great way to settle the mind from fear.

Having re-read this thread again I find that to be an interesting link.
Regarding cam test failure he had this to say; ...

Cams
• None of the cams met their rating. In two of the three cases, the failure mode was peculiar and undesirable (cable failure midspan, and axle shear).
• The Titan cam runner broke below rating, we tested with another piece of tied cord, it broke there again, then we tested without any webbing in the system and got the ball swage to fail at above the product rating.
These undesirable failure modes could be a result of age of the product, material selection, previous abuse, or a combination of all three.

Thats a great link- havent seen it before. And not just for the info on ukrainian gear- was interested to read the tests on belay loops. Often see people using home-made backup belay loops, so its interesting to get a few facts!

Hello Australian friends, I am a newbie here. Never been to Australia, I would sure like to visit sometime.
Anyway, I found this thread by doing a search on "Gear4Rocks" as they are advertising quite a bit on E-
Bay. Here in the US.
I have found this forum very informative, especially the links to Black Diamond, where they did the breaking
tests. Excellent info. I have a rack of about 25 cams (plus nuts and stuff) that I am narrowing down to about
20.
So I was selling my stuff on E-bay and I noticed this company "Gear4Rocks". Man they sure are selling a
lot of stuff on E-bay.
That is great that Ukraine is trying to better itself, I have always felt sorry for Ukraine with all that they have
gone through historically. What Stalin did to them was horrible.
But just looking at the pics on Ebay, the stuff does not look as "clean" as BD, Metolius, or Wildcountry.
Heck , you could always use it for aid climbing, and just place the good stuff where it counts.
I guess I am spoiled, but I want my gear to have good ergonomic design and handling, I don't need any
extra problems when I am free climbing on some thin crack, overhang 100 meters off the ground.

Wallwombat has found, due to his ownership of a full rack Ukrainian cams, no-one wants to climb trad with him anymore. You might be safer sticking to anything Ukrainian in a bottle:

BTW, I hadn't realised what Stalin did to the Ukraine until a few weeks ago when I went past the Ukrainian cultural centre (read: church) in Canberra. There is large memorial there to the seven million people (so says the memorial) who died in the famine called The Holomodor. http://en.wikipedia.org/wiki/Holodomor

Thanks for the info Mulchy. Not as exciting as I was hoping though. I thought this thread was being resurrected by WOmbat because one of his cams exploded when he slumped onto one.

I've got Czech Republic cams, and I'm slighly embarrassed by them. I keep seeking out partners who have BD cams.

I've got ball races threaded on manilla. What were you embarrassed about again?

I don't "slump" onto my cams!

No? But seriously, when you're running it out above one, aren't you thinking "will the Ukraine let me down right now?"

I've used them on Hammer and Sickle at Declaration Crag.

No. I'm generally thinking about the next placement and not falling off and stuff like that. No point messing my head up, thinking about whether a piece is going to fail or not.

There would have been no point buying them if I wasn't going to trust them.

... said he who made the exploding pvc tube chocks (and bicycle inner tube screamers?)!


BTW I reckon the super heavy duty O rings (approx 1 cm thickness-diameter), that can be found as gaskets for dunny plumbing fittings could be the better option for screamers...

You should have seen my aid rack when I was ten.

Thats not such a bad idea. SRT makes a shock absorbing sling much like a screamer but instead of the rows of stitching breaking a rubber ring elongates under a shock load.

Just making sure I've got this right in my head. Two biners through both a rubber ring and a sling. The sling will limit the expansion of the ring or catch in case of failure. Right?

Yep.

However in aid I have experimented with a giant O ring on thin gear, and still found some thin placements to rip.

How would the O ring help in an aid situation?

I guess it'd spread the load on the gear over a longer time as you move or weight the gear. Kind like suspension or dynamic rope but on a smaller scale, right?

Only problem with this i can think is that while screamers act by limiting the force to a set amount (2kN until its torn all the way?) rubber rings etc all act as springs, and from what i remember (several years since i've done physics, feel free to correct) is that as they stretch, each amount of stretch increases the force that is exerted at each end / to stretch further they need more tension which puts more force on the gear.
