Bottle vs. Constrictor
« on: July 05, 2011, 01:53:55 AM »
What is different about the uses of these two knots?
I know they are tied differently, and I can think of a couple areas where the constrictor would be more useful but, is there an area where the bottle knot would be better?

It seems the constrictor can hold tighter than the bottle in my limited experience, but with the bottle you get a handle.

Is that the only advantage of the bottle knot over the constrictor?

The Jug Sling Hitch (ABOK #1142) fills a niche for jug/bottle openings.  The Jug Sling makes a nicely balanced system for toting a jug/bottle.  I use this knot often for carrying water bottles.  It forms a death grip on the bottle that provides more security and more confidence than does the Constrictor.  Sure, you could use a Constrictor if you can't memorize the Jug Sling.  However, for the specific purpose of hanging a jug/bottle with balance and security, the Jug Sling is far superior.

Generally, the Jug Sling is superior where one needs a balanced knot on a convex surface.  The business portion of the Jug Sling is balanced across opposing sides.  The business portion of the Constrictor is unbalanced on one side.  As another example of when I would use the Jug Sling is if I'm hoisting a barrel/bucket.  Instead of using a Barrel Hitch (which I don't like), I'd tie a Jug Sling if the barrel/bucket has any kind of lip on it.

   Could you, please, explain this ? When the Constrictor is used as a binder, it is equally "balanced" on both sides, is nt it ?

I think he may be using the loop and the free ends to support the load of the bottle hitch instead of just the loop, which would balance things out.

I think.....

I think you're just being difficult...

The Jug Sling has crossing patterns on each side of the object (e.g., lip of bottle).  The Constrictor does not have such balance; its crossing pattern is on one side of the object.

The constrictor hitch seems to hold more force than the bottle knot, but it does not have the convenience of a "handle."
That is the only functional difference I can discern.


I was also confused by what you meant about the knot being balanced.

LOL... Nobody here sees how the Jug Sling has crossing patterns on both sides, while the Constrictor has crossing patterns only on one side?

I see that.  I just thought you where talking about balancing the load.  Like to hold it level or something.

   Sorry, knot4u, I am NOT difficult...not at all !  :) I just didin t get it. I see what you mean now, thanks.
This is not a knot.

constrictor knot is just two seconds away from a bottle knot  :)

Nice vid TY!
.
If it helps, what i see is >>
Constrictor used classically for round binding as so named:
has an internal radial/dispersed all around source force (radial swell) outward to the radial arcs that control the mechanism.
>>of yes equal force all around then thru rope
Constrictor used as Hitch tho by contrast is different mechanic by above measure:
has an external focused LINEAR source force input into the controlling arcs by contrast
>>would NOT have equal, but logarithmically receding force from SPart(Standing Part) input tracing to BE(Bitter End) thru those arcs
>>focused linear input force(harder to control) converted to dispersed radial(easier to control) at loss of conversion(capitalized on)
>>Can work, but also can spill open jug as pulls from 1 side/unbalanced
>>full force on single leg of support rope
(source of force type of Binding internal dispersed radial or as Hitch of external focused linear force input determine this equal or receding force thru arcs)
.
Jug Sling similar Constrictor in Hitch usage, but with dual opposing inputs of then pairs that serve to balance across to COMMAND jug to carry more upright
>>and not just from a 1D across jug hang of 2 inputs in a line, but rather lends to an even more stably sitting 2D platform hang from more of a square
more balanced forces thru arcs receding to center of radials from handle input pairs to same;
but at co$t of dropping initial locking input tension to radials from handles to 25%.
>>less force on rope handles don't demand quite as strong a rope then, tho in trade vs. single leg of support of Constrictor as Hitch.
.
Right tool for right job,
Constrictor simpler tie,  hitch carries skinnier and no spill anyway if screw on cap for pepsi bottle etc. to keep out nasties.
Jug Sling needs wider clearance than single leg hang, cuz upright from 2 points to hang from to do that.
>>but by that measure more proper for wider 20gallon actual jug, carried now more balanced across pole between 2people than if handles drawn together (less capacity now) more problematic balance i think.
.
Because of the wide carried 20gallon open top imagery
>>prefer original Jug Sling naming convention to convey the differences here.
>>our more common usage on pop bottle of today, does not convey the nuances as well to me.
.
Stiffer line may not seat as well after conversion in Hitch usages,
but don't have any choice in Binding usages against actual swell w/o conversions.
Thinner rope gives denser same force in smaller place type grab i think;
especially as center of rope less likely to extend beyond jug shoulder.
Jug Sling is one that can give that easier with less rope tensile needed/thinner rope more likely ok.

Wow. That really is an outstanding how-to video.

I happened to have a jar rinsed out on the counter ready for recycling and of course I have cordage to hand at all times, and I literally tied it in one viewing without having to pause or go back.

And thank you for just showing "how to".

Even before YouTube became intolerably laced with ads before during and after every video, the "creators" had got incredibly pretentious, treating their trivial offerings as if they were Hollywood epics, with little branding intros, previews, and heaven help up - even "credits" at the end, all for less than a minute of actual content. Meaning someone like me living in the country and paying big dollars for meagre MBs had to download 50mb to get 1/2 mb of useful information.

Sorry, rant over.

Seriously though, this video should be mandatory viewing for all video creators: Concise, precise, useful, usable and comprehensible.

Well done!

There is one small proviso - hardly worth mentioning really: It's hard to use this technique if the cord is wet and slippery.

So ...

Wait for it ...

I hope no one was alarmed by my last post about damp cordage.

If you've already tied your jug sling with wet cord, don't untie it! Just hang it out of direct sunlight in an airy place where it can gradually dry. The main thing though is to leave it undisturbed. Until it's completely dry, don't brush against it or jostle it in any way.

In other words, "Don't knock it till you've dried it".
