With the latest daisy scare rearing its ugly head again, I did a couple of tests that you might find interesting. I guess the only real questions I have now are:
1. Should we even be making daisy chains with just a small loop at the end?
2. Should we be only making daisy chains that a clove-able end loop?
3. Should we only make daisy chains with the yet to be named "insert".
4. Please advise....

Nice idea on the insert Fish.
Why can't you just use runner-strength bartacks for every pocket
on the thing? Cost? Weight? Too stiff? Dumb idea? Please advise.

Say Russ, I'm not really up to speed on this issue/thang. Why
is clipping the end loop like the first photo the Bad Business?
I thought the thing to avoid was accidentally clipping only one
of the bar tacks between loops, which puts you out of the system
when it blows. Otherwise with all of the pockets blown you should
still have one big loop with a six someodd bar tack keeping it
together.
Like I said, pardon my ignorance. I always have enjoyed your
tech weenie stuff. And don't forget those beers I bought you
years ago on Paypal. Ha! The photo illustrations rock, btw.

C'mon Fet... don't go all "Chicken Little" on us. Daisy
chains, when used properly, have tons of uses, including in and
around the anchor. If you know what they can and can't do, your
chances of survival are higher, but I hardly see stiffs stacked
at the base of routes like cord wood from daisy failure. YMMV.

Nice idea Russ.
If you take a short piece of webbing, pass it through the last
loop of a standard daisy and bartack it closed into a loop so
that it floats free like a link of chain, you've got a full strength
loop at the end that won't get loaded funny or pop open.
Makes for an easy way to retrofit existing daisies.

But, as Russ pointed out,

Couldn't we just use two 'biners and call it a day?
We're discussing a way to prevent improper use of equipment from
killing us, rather than discussing the proper use of said equipment.
Unless every manufacturer of daisies changed their design, a
new "specialized" daisy developed by one manufacturer
still doesn't stop people from using other daisies incorrectly.
This doesn't seem the best way to go IMO, especially since the
solution is so simple.
The flaw is not in the design, but in the use.

Thanks for all the work Russ on the daisy chain, BUTT.... I've
been using the daisy chain gig for over 14 years (I used to do
alot of climing with a 3 person team and switching ropes, arguing
over who got the next pitch was easier). But the daisy chain
is for convenience people, to easily adjust a semi hanging stance
at belays and feeding T/R's. Why doesn't everybody tie in to
the anchor point with the rope, remember that colorful thing
you've been trusting your life with up until the Belay?. Tie
a Freakin backup knot on your lead line, clip your daisy correctly
to allow a semi comfortable stance and let Darwin take it's course
on the rest of the idiot nation that has to be protected from
themselves.
Leave the Fish alone to test shoes and perfect the perfect econo

Mark ya dolt!!! That is just the point. For that split second
where you are into the anchor with just your daisy, and you get
light headed and untie from the rope for an unknown reason, then
you decide to clip the haul line from your ass into the bottom
of your belay loop along with the daisy chain, and then your
partner uses his belay knife to free the 400lb haul bag from
the lower anchor prematurely, and it goes all the way to the
end of the 600ft static line... THAT IS WHY WE NEED A BOMBER
DAISY SYSTEM!!!!!!!!!!!!!!!

Unless you're worried about the whole loop breaking (i.e. the
full-strength sling bar tacking that makes it one big loop) why
is a clove hitch any better than jsut using a girth hitch? This
takes up quite a bit less of the sling...
Re: Daisy Death revisited
Apr 27, 2006, 06:37pm PST
Author: Russ Walling
A girth hitch would be fine, but,..... if your girth hitch is
not cinched up real tight it has the potential to walk up the
biner and then when you load it, it unclips itself. Just did
it myself as a test.
addendum: I was goofing around with this some more and if the
girth is not real tight, you can wiggle the biner around enough
to get the biner to come out of the hitch and fall to the ground.
Remote chances at best, but it is repeatable in the lab.

Russ, if you are still working on this fool-proof daisy for anchoring,
I'd recommend reading this thread.
Daisy chain question.
http://www.rockclimbing.com/topic/111061
Here is a quote from Largo, in turn quoted from an earlier RC
thread:
Largo wrote: pg 5 of sliding x thread
Quote:
"That's why a person should never tie into the anchor with
a tech cord/web daisy. A daisy made out of anything but nylon
is a serious liability because it can cause shock loading (as
seen in the recent Rock and Ice expose). You ALWAYS tie into
the anchor master point with the climbing rope. NO exceptions."
Jim at Sterling has been drop testing daisies, etc. Defineatly
stay away from spectra/dyneema. Here are some select quotes from
sterlingjim regarding some very high force tests:
"Spectra daisies or slings should never be your sole connection
to the anchor and probably should not be your primary. It's not
the force of your partner falling in any scenario that's the
problem. The problem is you falling directly on the anchor while
attached with a very static 'umbilical'. How could this happen
if you're hanging on the sling? Suppose you step up for some
reason to adjust something or fiddle stuff around then fall backwards
and BAM! You may break the sling, you may break your back, you
may crush your kidneys. A whole bunch of unpleasant things may
happen. Of course it's entirely dependent on how long the fall
is but static materials care very little about fall factors they
only care about force and how quickly it is applied.
Here is a sample of the tests:
11/16" nylon, impact force 18.4kN, held
1" nylon, impact force 21.11kN, held
1/2" Spectra, impact force, 20.02kN, failed
5/8" Spectra, impact force, 19.2kN, failed
10mm Dyneema, impact force, 18.9kN, failed
The impacts listed were the highest recorded out of five drops
on each. All nylon slings held. All Spectra and Dyneema slings
failed. All slings had a minimum rating of 22kN. A fresh sling
was used for every single drop. It should be noted that even
the nylon slings recorded very high impacts, high enough to threaten
the anchor and certainly high enough to cause serious personal
injury."
He also tested the Metolious PAS:
"OK, standard disclaimer: this is a very severe test and
should not be considered conclusive in any way.
the results:
They died quick and painless.
Sample #1) 21.5 kN at 0.014 sec. broke
Sample #2) 21.7 kN at 0.018 sec. broke
FF just under 2, probably about 1.9. Mass 80kg. Drop distance
48"+/- 2"
So, it looks like good old nylon slings maybe the best thing
we currently have to anchor with, if you can't use the rope.
With a nylon daisy you are looking at possibly ripping out body
weight pockets and ending up with a compromised sling due to
all the ripped out bar tacks.
-The sky IS falling, or is that just cord wood, or perhaps parts
of alien spaceships.

Personally I like cald's design (above) with reinforcment tucked
inside the next to last pocket. simple, clean, probably cheap
to manufacture. Having the extra piece tacked on the end like
Russ's makes me nervous.
But I have a feeling that now that this is a public issue and
the risks are well known any manufacturer who doesn't change
their design is going to get their butt sued if a dad with 5
kids blows out of his daisy and decks. Current designs really
are defective to my mind.
Of course there is always a work-around, clove hitch or two biners
but hey, sh#t happens and not everyone reads supertopo. Why do
we wear seat belts.
Personally I rarely belay off of only a daisy but I've probably
done it, and probably shortened up by clipping a pocket. I also
use daisys for jugging and again shorten up by clipping pocket.
Glad I never had the opportunity to shock-load the system.

I vote for no more dasies with small loop ends- you can't hitch
them and there are many unawares that will only use one biner
to shorten and not twist the daisy.
Also, maybe in the tags for purchae there should be instructions
on the best ways to use and the worst ways to misuse.

Years ago I tied a simple Overhand knot in the last loop of the
daisy to prevent the death scenerio, this made the last pocket
smaller. This was a Spectera Daisy, which has it's own problems,
and the knot ended up being fairly small but has served me well.
Any reason why this can't be the solution going forward rather
than many stitches and bits of webbing?
First daisy I ever owned was a big ol sling of 1" tubular
with a heap of overhand (doubled) knots in the sling creating
pockets. Far from Sexy, but safe just the same.
Any tests with that config Russ?

Yeah, most of the time, you're never going to be able to replicate
these falls that tests show break runners. It's highly unlikely
to take a factor-two fall directly onto a completely static anchor.
That said, I would prefer a dynamic link between myself and an
anchor, as my *body* would probably break before the runner did.
I'm wondering why no one has looked into a kernmantle constructed
anchor system modeled after rope and dynamic to significantly
lessen impact forces.
Probably too expensive to R&D.
I stick with the contention that your best safety practice is
not to fall off the rock.

Seems folks have been sporting the Daisy-of-Death™ for quite

The Death-Loop scenario has held sway over climbers for decades;

Dudes,
Am I understanding that throwing an overhand in the last loop
will prevent the magic trick? And although this works we are
trying to come up with a better solution? This is how I have
my daisy rigged as it made sense to me, but I had to flip the
damn thing around because it is a BD and the end loop was too
small for this. So, the end loop is really the harness end and
vice versa.
Also, and yell at me if this has been said, rather than adding
a loop as the above suggestions stated with dual bar tacks and
what not; couldn't you just make the last bartack full strength?
That way you would have one bomb-ass pocket at the end of the
chain, and if the others blow your still set. Right? I guess
what I am saying is that I see how the "insert" is
cool, but if you are going to start making them like that, why
not just bartack the last tack to the max?

Author: Burns
Mack is right, we're overthinking this.
Several pretty simple solutions (that don't involve buying new
gear) have been presented:
An overhand in the last loop
A clove hitch in the last loop
Shortening your daisy with a second biner, leaving the anchor
end biner through only the end loop at all times.
Shortening your daisy with a spare biner from the harness end,
like you do with your fifi.
There's probably a few more, I prefer the fourth option as I
found the clove hitch to be a pain the the crapper when I wanted
to flip the biner, hadn't tried the overhand yet, but I don't
think my loops are big enough. Second biner on the end of the
line seems like a pain. Also, I have a misty nylon daisy that
has a pretty small end loop, so when I tried out the clove hitch
option, I just flipped the whole rig around so the girth-hitch
loop became the end loop since it was bigger. Still don't like
the clove option though.
Of course, none of those are idiotproof like a special for-idiots
daisy would be...
Edit: If you did produce a daisy with the extra bar tacking,
etc, you could call it the FID (For Idiots Daisy), kinda like
the metolius PAS.

OK so here is my 2 cents worth. Why do any of those options (other
than full strength bar tacking all pockets)? I have never liked
or been comfortable with girth hitching or clove hitching or
over hand knotting one material to another particularily when
they are of differing dimensions. IMHO the easiest answer is
to just attach your daisy to your harness with a locking carabiner.
No knots no fuss full strength.

Russ, I did read it all and I thought most were in agreement

That is what I was refering to. Modifications to the biz end

Most likely is far and away an improper clip in the middle of
the chain. I've read your posts a few times now and I'm just
not getting what you are saying. If you watch the BD video, that
is the scenario we are trying to get around. Your attachment
point to the harness, be it girth hitching, locking biner or
8 wraps of duct tape has nothing to do with the failure scenario
in the BD video.
Re: Daisy Death revisited

Author: ADK
The issue is when you double clip two pockets. Lets say you have
a locking biner attached to the end loop in your daisy and you
decide you want to be a little closer to the anchor. So you clip
another loop of the daisy into the locking biner to hoist yourself
a little closer. If the stiching blows out between the pockets,
and you havent put a twist in the chain before clipping the second
loop, youre going for a long ride.
When Im free climbing, I tie in with the rope. When Im aid climbing
I tie in with the rope and adjust height with the daisy in the
dangerous method but I have a backup always.

Author: philo
Russ I know what you are saying and I agree. I am only saying
that friction of nylon on nylon is a very real risk probably
more so than a pocket blowing out from shock loading an improperly
adjusted daisy. BUT, the constant wear and tear at the cinched
tie-in is a potential and usually un-noticed failure point. You
don't lower someone by running the rope only through a piece
of webbing. That should be obvious. But what probably isn't so
clear is how much damage occurs little by little to regularly
loaded girthed or cinched webbing material. My original post
was just to say that by eliminating that weakness
you inherently improve the safety of the system. Manufactures
clearly state that girth hitching or clove hitching webbing redices
the inherent strength by 50%. Why compromise the system before
it even gets put to the test? I hope this clarifys my earlier
(somewhat off topic post).
For the record I use a daisy as a personal safety teather only
never for critical uses like anchoring.
Also for the record your wall gear has always been the greatest!
Thanx.
