Im Knots About Climbing

Yeah, your comments always make me laugh! like this one:
>(but I HAVE seen them loosen - in particular with very new thick/stiff sheafed ropes)..
Me too but only a single bowline NOT rethreaded, and only in work statics that are so stiif they are
more like cables, so they want to try and straighten out and don't bend very well, with short tails and
lots and lots of movement they can even come undone!!!!, but that's not what I'm talking about is it!?
I'm talking about the knot that's in the picture above, tied in a supple and flexible climbing rope, and I
also believe in checking/rechecking, this is not a magic cure all for beginers, just a really really safe
tie in thats easy and practical, your ranting comments like:
>a discipline of checking and rechecking a knot rather that teaching a magic knot that will cure the
>heathen beginners of all their ails...And moreover I think that the latter is more dangerous"
blah blah etc.
seem to make me feel that you are incapable of learning a new trick, in other words you are stuck in a
habit ritual that only lets you feel safe if you do things a certain way, and don't ever look outside your
box! at why you do that ,you've been told do it thus and so, you don't question that, merely repeat it
without really understanding why, but it makes you feel safe! thats ok, I got a little insight into your
mental workings with several key comments you made about "short safe sport routes", and "people
crazy enough to multi pitch", etc, so I get it I understand where you're comming from It's OK just relax
and breath, it will come more slowly for you, thats OK, take your time, when you're ready you will try.
PS. I'm not evangelical about my knot, I tie kids on 8's all day long, just trying to show you (those
willing to listen) something thats cool and works well, It's the whimsical crap that makes me think
you're stupid or slow or both, thats all! the bomb

NICE!
Ever the diplomat eh Bomb?

I'm still not convinced by the 'tie in one motion' thing. Sure, if you 'half-tie' the re-threaded bowline, you've got a single bowline - which should hold ok. But if a single bowline's ok, why didn't you just tie it in the first place?

It seems to me that the real benefit of the re-threading thing is that it stops the problem that you can have with a normal bowline being loaded across the bight (as discussed above).

Anyway - I'm sufficiently convinced that I've been tying in with one for a while now. But the way you go on about it Bomb anyone would think you had shares in it or something...

Some interesting thoughts here amongst the ribbing. I've never used a bowline because I believed that the forces at the knot where significantly higher. I have seen this tested with both the 8 and the bowline tied in line and then stretched to breaking. The Bowline always broke first and you could actually see the melting on the sheath.

But having said that I can see the idea behind the re-thread bowline as pictured. Good point about never having the risk of leaving the 8 on the end of the rope. I have never done this, but a few newer climbers with me have. Also, I'm not a climber that takes lots of whippers on a sport climb, but I am thinking of giving it a try. I can see where this would be a much easier knot to untie than an 8.

Reminds me of a guy I climbed with who had had some alpine training. He used to thread an un-knotted rope through twice and then tie half a double fisherman as the stopper with a 'decent' tail. The fisherman would then be slid up the rope to the harness bringing everything tight. Personally, I could never bring myself to use that one. Thinking about it, you could never trust to clip into the bight.

I would always teach an 8 to beginners. Just seems to be a good starting point.

Just a few thoughts.

thats how they do em at the gym i route set for pat- 2 biiners; 1 on an a.butterfly and the end one with a dbl fishermans. seems to do the trick but i cant imagine what the advantages are

I stand by those comments, if you stand by your comment about the bowline put under some wierd
pressure crap, cos that and concern about clipping the bite (god knows why you would do that but...)
are just stupid! and if you are being whimsical to me in your comments on purpose, then you are slow!

one length of sling is worth 22kn wrap it twice around, ie double it, and it's worth 44kn, do the math !

of course that can only happen if you are loading a section of the knot that cannot come under load in
the normal use of this tie in, you are again demonstrating your ignorance of the mechanics of the knot.

Glad to hear that you use it on short safe sport routes (although this makes me feel that you don't trust
it, and so only use it when you are close to the ground on "safe" sport climbs whatever that means?
And as I have said I DON'T CARE WHAT YOU TIE IN WITH and don't have shares in it!
But I can't help but try to educate you, as you clearly demonstrate that you don't know what you are
talking about! on a regular basis...the bomb

I have almost always tied in with a figure eight and a stopper knot. An easily recognised knot that makes it easy to confirm. (And I have never had to cut the rope because I couldn't undo it.) I have occasionaly tied in with a double bow-line. I certainly admire Bombers typing abilities including his excellent use of the caps shift key though I usually wouldn't bother reading the crap he writes.

1 Use what you're familiar with unless there's a good reason
2 Figure 8 is strong (~ 80% efficiency) easy to check, both on yourself and on other people. But if you simultaneously reach my magnificant build, and are taking a lot of falls, you will get strong fingers trying to untie it.
3 I believe that the rethreaded bowline (or bowline on bight) is a bit better than a standard bowline (which also put Adrian Coper, who taught me and Kim and Saxon and Mark baker etc climbing, in hospital). It is a bit more obvious if it's been mis-stied, it's stronger (>> 60% efficiency), and it doesn't need a stopper really.
4 Bowline is easy for tying off trees etc, use a double barrel stopper knot though.
5 Despite the low apparent strength of a bowline, ropes always break somewhere else.
6 One advantage of the figure 8 is that more rope is dargged through it in a fall, thus absorbing energy. This may be one of the reasons for preferring it to an overhand knot back in the hemp rope days
7 90% of the time I use a bowline on bight, generally with stopper, which is always untied by the time I top out. it gives me something to fiddle with when i get scared.

Just to clarify what you are saying Mike. The normal bowline put a few people in hospital, but most of the time you use a bowline on a bight. So you form a bight first and then make a bowline using the whole bight?

Um, not so sure that this is how forces work. If you have one sling that has a max force of 22Kn, then having two slings will distribute the loads between the two slings rather than increase the overall strength of the sling.

Isn't it like adding a teaspoon of sugar into your coffee? even if you add more or less coffee you still have the same amount of sugar -unless you start to drink it and then add more coffee...

BomberPro have you got a Dr Jekyll and Mr Hyde complex? You swing wildly between being amicable and being down-right obnoxious. Here you are calling everyone stupid and slow again! You're being abit hypocritical when you choose to quote from TV shows such as Ugly Betty.

I think the 'bow-line' on the bight Mike is referring to is Bomb's rethreaded bowline. I think it is called that because it can be tied on the bight (when you don't want it through your harness).

Bomb will probably educate me about this though and remind me I'm stupid in the process...

That may be Ronny, but a re-thread will be slightly different. A bowline on a bight will have both tails going through a double loop as it were and above the stopper knot you will have the end of the bight, which will be a loop. Maybe someone out there can find a picture or draw one if you know what I mean. I just tied one here in my office with a spare phone cable and it looks a lot different to the re-thread, but a whole lot quicker to tie than a re-thread figure eight.

if you can't tie a knot then just tie a lot!

The thing that I call a bowline on a bight is where you pass the tail around the rope then tie the bowline.
When pulled tight the rope will cinch up against whatever has been put in the loop created between the
knot and the rest of the rope. It's good for hauling soft things.

Having just consulted my copy of "A Fresh Approach to Knotting and Ropework (Charles Warner 1995)"
there are 31 variations on the bowline. I have decided that the Splayed Portuguese Bowline should be
adopted as the standard, as I got splayed in Portugal once and it was great fun, although some of you
may prefer the Cowboy Bowline, but then each to their own.

On the subject of figure 8’s. Just to be pedantic you are not going to get any security from a figure 8 knot
as it does not form a loop so therefore cannot attach to your harness. A double figure 8 on the other hand
does form a loop.

The double figure 8 does have a tendency to lock when loaded. To remedy this you can either start
climbing better so you don’t fall off so much, or alternatively try a figure 9 which adds one more turn to the
8 and can be a little easier to untie. Warner (1995) goes on to describe the Stevedore Loop which adds
further turns. “The Figure 9 Loop and the Stevedore Loop give grater security than the Figure 8 Loop”,
(Warner, 1995).

Who’d have thought that tying knots could be so much fun……lordy lordy lordy. You could probably tie on
with a clove hitch and still survive a decent lob. I encourage you to tie on with what ever floats your
pontoon, and remember if pain persists consult your Doctor.

I've confused everyone - I've been calling it a bowline on bight which is also a rethreaded bolwine. A double bowline to some people means you start by making a double loop for the rabbit to go through.

Why doesn't the maths work like that?

Doubling a sling will pretty much double the force it will hold. (To be technical there will be a slight reduction due to the turn radius). Similarly you could hang from a 'single' piece of cotton thread could hold your weight if you wrapped it back&forth between your tie in point and the hang point 1000 or so times.

Is that same or similar to a passback, which I use to help me unstick the knot after loading it with a flying 105kg.??

Thanks dodw - just what I needed. *you're* the best.

I think the re-threaded bowline is sometimes called a bowline on the bight because you can tie it like this: http://www.animatedknots.com/bowlinebight/index.php

You obviously can't tie it like this onto your harness, so you re-thread it.

No, I've ascertained it's not.

I use a figure-eight with a passback - end is passed through the knot again, with a bit of a loop - you can hook finger into this and pull to ease the knot after loading.

Anyone got anything bad to say about this?
