Lubing carabiners

[SoonerFan]

I don't have a clue, but... 5300#.

 

[wiley_p]

What a trip. We weren't even close. First one broke sat 2658, second one broke at 2143. Sounded weird too, not the sharp crack that aluminum biners make usually. a real soft sound like a french fry snapping in half.

3800# failure with deformation starting at 2000#

:edit doesn't matter Dave posted while I was.

 

[sotc]

Wowzers, definitely affected

 

[pete mctree]

That's a shock indeed. Have you got some pics Dave?

 

[wiley_p]

I'm looking for my camera now. I'll get some pics then load them when I get home. The computer in the rigging room don't have a sd slot.

 

[SouthSoundTree]

Cool. Worth testing.

30 kN marked on them-- 30 x 225=6750 pounds rated.

I was gonna say 2400.5

 

[SoonerFan]

Jack, you are a genious. Your guess was EXACTLY half way between the two.

I'm impressed.

 

[CurSedVoyce]

I was gonna guess about 1/2 rating... slept in.... I'm a slacker.
Can't wait to see the pics.

Sean - have you got any more of those krabs ?(similar age & usage would be amazing) Would be nice to get a control test. Will pay for the tests & krabs etc if that's an issue.
I have been cleaning krabs by gentle boiling in water for years & the results are of great interst/importance

 

[Burnham]

That's for sure.

Pete, do you keep them off the bottom of the pot?

 

[pete mctree]

I always throw in bits of broken ceramic to keep it off the bottom Burnham & keep the temp as low as possible. I want the bubbling action to clean not superheat the krabs . I am re-thinking my methods as I type

 

[Burnham]

I used a small trivet the last time I cleaned a batch...I like the idea of using the steamer basket that Stephen pictured, and I have a couple in the kitchen. A metal colander in a large pot would do as well.

With the basket, one could heat the water to just under a boil, then turn it off and dunk the biners in and out repeatedly. That would agitate the water to assist cleaning, but not be so hot.

 

[SouthSoundTree]

I don't know what brand of 'biners those were. I looked on Wesspur and Sherrilltree's websites, but without luck in IDing them. I would have almost 100% have gotten them from one of those two sources, only having tried out TreeStuff recently. I suspect that those were purchased 2-3 years ago.

Sean: We're up here in pitch country... WD40...

 

[MasterBlaster]

Bubbling action?

Hydrogen peroxide?

 

[Tucker943]

Why not?

 

[MasterBlaster]

It bubbles like a mofo and is room temperature.

 

[Tucker943]

I'm game.

 

[stig]

Just hang them in the jacuzzi!

 

[sotc]

Thats what I was thinking, wear your whole harness in the hot tub

 

[Porkbrick]

now the wife is going to be REALLY confused! rope in the washing machine, biners in the sauce pan, saws everywhere, and now harnesses in the hot tub!

A word of warning on cleaning chemicals for aluminum alloys, magnesium and Titanium.

Caustic chemicals, heat and loose hydrogen molecules can lead to hydrogen embrittlement.
If heat is involved, dish soap is all I would want to use.
