Ultra Tech Prusik Eye

Gunslinger

I just purchased one of these and was wondering what kind of eye splice they used in making this? I looked through the Samson splicing guide and I see no splice that resembles this eye. Also it says that it's rated for 5400#'s which seems like an awful lot of weight for just the core of the rope going around a carabiner. Anyone know what kind of splice this is and what the shiny hard substance is on the eye's?

Hey Gunslinger, ill give you a link to some posts over at another Arbo site where this topic is covered in a bit more depth. Basically they are discussing ''Bee line', but the splices I think would be similar, not sure on this, just generally speaking.
As far as the stuff they coat the ends of the splices with I think it is a urethane of some sort designed to protect the rope and increase it wear resistance.
Each rope manufacturer seems to have their own proprietary brand, Samsons is called Samthane IIRC, and so on, and so forth
So heres a link to splicing discussion regarding Eye to Eyes, enjoy....



Have a good one,

The core is the load bearing part of these type of ropes construction.

The inner core is 12 strand hollow braid.

The outer sheath is there for abraision resistance only.

It is a very simple splice. The waxy dip coating helps protect the naked eye.

Here is an old one opened up...




This one shows the splice a bit better...

Trev,

Thanks for the photo's. So the inner core is just sort of woven through itself. Interesting.

TrevMcRev

Yep, the braid is parted in the middle and it punches through twice then gets buried in the core & whip locked.

The 5400lbs is tensile strength, WLL is 10% or 540lbs.

Trev is bang on the money.

Its called a locking brummell. Remember, a brummell can reduce rope strength by upto 50% and is the least efficient splice in terms of strength.

Awesomely gay about not being able to post links, what are we scared people might find more info on another site, or worse yet get the wrong info not treeworld approved.
Haha how sad indeed.

letigre

so is there a better splice to do then a brummel? also anyone know of some cheap beeline substitute to practise splicing?

Thanks for the name of the splice. New England ropes has some information on making the Brummel splice. It's here if anyone is interested:

Well, the site you linked too is also awesomely gay too then as they dont allow links either, especially to here.

What is sad is you condemn us for the exact same rules they have! Haha how sad indeed.

Go research my posts there and see how many idiots on a frequent basis I have to educate and set straight.

We're not scared of anything here, in fact, we're one of the best sites you'll get that isn't cluttered with off topic BS.

First off, apologies for getting snotty, there was no real need for it.
Ekka, I know all the sites do it, by that I mean blocking off site links and such, doesn't mean it isn't kinda 'gay' IMO.
But I cannot even send Gunner the link in the PM, I would think that woulds at least be doable !

Please don't take it personally, as far as sites out there, I have done some research, maybe too much, Tree World is a nice site, but it contains a relatively small group of climbers, and therefore the info therein is kind off limited.
Again please do not take that as an insult, I don't mean it in that way, I just mean there is a lot of other info out there, and yes while some may be shite, there is lots of good stuff as well.
Some may prefer the more intimate, smaller Tree World setting, some may prefer others. Im sure some people like the fact that you get to keep a close eye on what gets posted , and they therefore feel it is a more trustworthy source of info, I totally understand this reasoning, and even agree with it.
That is the problem with some of the other sites, there is so much info at times it can get overwhelming.
Anyways do stay safe up there,

Better in terms of what? It really depends on the application, rope make up and material.

I reckon the brummell is perfect for a eye to eye prussic, climbing 2;1 with the load being spread over both the eyes thats only 25% loading on each eye.

TrevMcRev

I can get you 10mm Tenex. Like whoopie slings are made of but smaller dia.
It can be used as a prusik but is not high heat resistant. Ok for hip prussik on a flipline though.

The rope is the same construction as the core of beeline etc. but has no outer jacket.

Eric Frei

Cool, it goes like this.

TB: full of climbers but little about trees.
AS: Full of chainsaw, religion and political crap
TH: Full of jail birds and rejects
AT: Full of poms with attitude like Ted Boreman

To link in PM's use this facility to convert the URL into something that doesn't get word banned. Dont do it on the main board though.

TinyURL.com - shorten that long URL into a tiny URL

To a degree we are above climbing here, where others get a hard on over it, talk gear and the rest, to us it's just another tool/method of access to do the job. I might write a spec for a treework, the arborist needs to know how to do it, use an EWP or climb etc. Most here are well versed in all aspects but the more important aspect for many of us what has to be done and why rather than how. Many of us know the how.

We are a group of people that when you walk into Mrs Smiths yard and she asks, "what is wrong with my tree and can you fix it?" we have answers, that's quite different to when you walk into a yard and the HO asks, "so how much to cut it down?"

That is probably the largest difference for us here. We still do tree work however we're an evolving community with tree care at the forefront, not chainsaws and who can get to the top of the tree fastest.

You'll see question go unanswered about who won a climbing comp, to many of us we don't care.... but there are champion climbers amongst us who do care for trees and share their stuff like Jim1NZ.

so a class 2 double braid isn't better? or is it just more time consuming for not much benefit? sorry im a complete splicing beginner im going on what other people tell me.

also you know of any cheap double braid to practise on?

well said[even though i do my own electrical work].

hey tiger

class 2 splice is for ropes made from high modulus fibers like dyneema. it has a long bury. using the lock brommel you can make a shorter eye to eye sling

any 12mm double braid rigging line will be cheaper than beeline. make sure you are using the correct splice for the rope you are using

(WLL)

BTW TH sucks the owner has AIDS from sharing needles and he has been busted with more child porno then your chip truck can handle!!! Birds of a feather flock together so stay the HELL away from the TurdHouse.

the locking Brummel or whatever ya call it is used so you dont need so much tail bury on a short eye-n-eye. they work great with the right app..
