Swabish

[BigJohn]

Here is a look at a 16 strand swabish I just made up for friend. I haven't seen anyone use one before.

This is to replace the one offered by New England wich is made from 1/2 double braid that herniates at the eye. 16 couldn't do that since there is nother in the eye of the splice. I know a who puts a little something in because he likes it to stay round and not flatten out.

I heard that there is more strength when it is flattened like in webbing.

I climbed with one like that but a little shorter. This was the first closed ended hitch i used several years ago. it has a little to much surface friction for my likeings.

i think that 16 strand has a core to not let it flatten out to maintain so much strength/material per inch, also flow around limbs better, with less friction, from less footprint on the limb.

When a line arcs around a curve the inside curve fibres are relaxed and not carrying/pulling load; while the outside fibers are teensed and the load is leveraged on them(same as offside holding fibre in hinge). Having almost zero distortion of shape, flat rope (webbing) loses much less strenght in a bight/turn, as there is no internal arc getting much less leveraged load than an outside arc (cuz webbing is flat).

So i can see a case for saying that the flatness won't affect strength, but i question the 16strand application, as the engineering of the line i beleive was so that it doesn't go flat, and stretch out. i've called Samson before on a similar deal to this. They warned against it; don't know if that is jsut to reduce liability etc.; but i jsut stuck with their advice.

i have taken the center out of a double braid, the outer tube does have unique characteristics for friction hitches. I backed out, as i was delving where i might not should. i had worries of strength, and heat build up on thinner 'line' with more friction contact. Guess i jest chickened out!

Bigjon, how does 1/2" arborist climbing line work for a prussic cord?
Is it more better than thinner cord most guys are using?

 

[Tim Gardner]

1/2" 16 strand works great for my VT hitch.

 

[John Paul Sanborn]

WOW that looks way too bulky for me, the reason i went to 5/16 is because 3/8 was too big. Ther knots are too much in the way.

 

[Tim Gardner]

How do your knots get in the way John?

The 16 strand is the smoothest runing cord with the least amount of resistance when pulling out slack that I have used so far. Also, I don't get the wear like I do with double braid.

 

[Tim Gardner]

BTW JPS, dosen't that 5/16 tress cord get way too hot on descent? I have burned the tips of my fingers a few times not to mention a few tress cords.

 

[Tim Gardner]

Here is a picture of the 1/2" and 5/16" hitches side by side. Yes I know that is a nonlocking biner with the 5/16" tress cord on it but it is just for the picture. I used two CMI micro pulleys because I have only one Petzl micro but you get the point. Not a whole lot of difference in size when you compare how the 1/2" works vs. the 5/16". Maybe a week from now I will find another hitch to keep my interest.

 

[John Paul Sanborn]

IMO there is s significant differenace in bulk there.

But then I sat potatoe and you say whatever you please, since this is America and discent is one of the courner stones of the Republic.

Well at least until last year, then i digress.

My cord lasts me a few weeks, at around a buck a peice, I'm ok with that. What is a little blister with all the nicks and scrapes I get on a regular work day. Most of my burns are from touching the climbing line on decscent. On long raps, I may use my Piranah over the friction hitch.

 

[Tim Gardner]

JPS, what krab did you find to work with the Piranah? While at the rock climbing store I tried the biners recomemned on the box the 8 cam in but neither one of them fit. Did you have to remove the black plastic insert? How does the Piranah work compared to a standard 8?

Presently i am running out some 3/8 dbl. braid from the collection; taking aim at the suggestions for chords after that.

i Presently am tying 3 ring anchor hitches back to the host line (kinda like barrel/fisherman's only with the stacked rings standing straight up?) on each leg of a knut hitch, that sits sqarely on the anchor hitches with no slack making a tight stack, giving better more immediate self tending, when pulling down and not just to the side. Probably drop to 2 rings for more compactness, been making 3 for years. Kinda think i like the stack of rings to stand tall, not squashed and wide (anchor/barrel). i make one witht he tail barely ssticking out the end, thighten and dress to the long end, then superset, by pulling the tail out for the length of the ~1 1/2" of tape, to furhter set/tighten (anchor/barrel).

i don't untie the anchor hitches, in fact am experimenting with a plastic thimble in one of the temporary eyes formed. i don't untie the other one either, yet tie the knut, with the bulk of the knut resting on the hitches flat; ending up with no slack. Done by, lacing, then pulling the slack into the final eye(slack that you needed for lacing the bulky knot through the final ring of knut), then 'girthing' the slack in eye around the 'krab', using all the slack. Thus ending with all of the slack taken out and the knut hitch sitting flatly on the anchor hitches, giving more immediate tendng IMLO.

To even increase that, i have been trailing the loose tail of my line through the linking krab, as Brian recommended doing with a friction hitch lanyard to make it self tending. Using the link as the tender also, nice, simple and clean; multi use! More mechanics without the hardware. This that worx with the worst of the self tending knots, worx well with the best too! i take the line out of the krab (tending wise), and flip it over my shoulder for any real descents, for as the speed + 1/2 twist effects spiraling in the trailing line. Just walking out and feeding doesn't seem to affect the extension of line quite the same in that instance, so i guess that is slow/short enough that spiral are less noticeable and or not as much spirals produced/held.

i wouldn't use a bowline for a tail, save perhaps coming off 'all in one' (basic/no split tail), as the yosemite feeds up nicely to friction hitch the host. Especially on a snap that you might not be able to get - anchor to self/barrel off a closed ring. Otherwise it is a choice for temporary eye on end of lifeline, offering a fixed eye. i really like it for rigging Krabs&Sling Sets into the open eye of the dbl.bowline with tie off all day.

Yes, signifigant bulk. i agree.......

You guys think my hitch is bulky, check thetreespyder's hitch out. it is the middle image in the picture.

[Tim Gardner]

Still too much bulk?

 

[dbeck]

jps and rockyjsquirrel: what are you guys using that is so inexpensive? I use ultra tech currently that costs approx 10 cent an inch or 1.20/ft. Does your cord compare to ut in performance?

 

[TheTreeSpyder]

Geeeeeez now, along with everything else, now i can't even attack JP's signifigant bulk ............. i really feel useless around here now!

But i guess it is only paranoia when they are not watching like both my shrinks say, yes i meant i used to be taller, at least men-tall-y i think, but just maybe dreamed.

i think this more recent picture more accurately goes with my most recent post IML,H,A,O.

Sorry Nick, i tried...........

:alien:

edit - actually, have another knot tending deal for this self tending on the stack, still playing with, polishing....

Thanx Brian (below), do these cords for short term use (?) work well in lanyards longer term use/ no speed? Notice the 3/8 dyed line is = in strength to the 5/16 white. Samson explained to me once that was because the dye moleculses took up space too, so more actual strength rendering line in white package of same diameter. There claim was that the dye didn't weaken the line chemically, only material wise in the amoutn of space given.

 

[dbeck]

Thanks for the link and info rockyj; I just ordered some to give it a whirl.

 

[John Paul Sanborn]

I got a 600ft spool of 5/16 sb and keep it in a 5 lb kittylitter box in the truck. I can cut a hank whenever I need it and give people a tress cord and sell long hanks like a small time drug dealer to help support my rope habit.

And that bulk that Li'l Kenny has is so a stiff breeze does not blow him away, or is it so that the groudies can spot him when he turns sideways

 

[TheTreeSpyder]

Hey now,

i have put on some real weight,

so ya's better watch it

(yeah, the rumor about me carrying 2 extra karabs is true!)

 

[Stumper]

Rumour has it that Spydy's original "stacked 'biner" and hitch arrangement was the same size as Spydy himself. He says he has gained weight but I heard recently that Ken's biggest groundie is still setting line with the bigshot using his boss as the throw bag. This is why Spydy is so productive despite his verbosity.
