amsteel blue rigging false crotch?

i have been looking into getting a couple of ring and ring false crotches made up consisting of the amsteel blue line, i know that it picks easily but i figured some cheap protective tubeing would sooth those sorrows, what i was wondering is if the amsteel line can be spliced that tight to accomodate the rings without having to use any thimbles?

i chose this line because of its "easy" splicing and high strength, im hoping that all answer "yes, it works great, go for it, your the coolest guy ever" but am also aware that i may not get all of these answers, what do you think?
 
I've spoken to the guy from Samson about this; he told me it doesn't have even a tiny bit of stretch to it. This means more shock to everything in the system. Otherwise it sounds great...if one can afford it.
 
At high loads, I encourage people to go with a solid thimble. I'm not sure how much strength you lose if you go at a 1:1 bend radius (like 1/2" rope over a carabiner, for example)

Oh, and they sell a covered version of just about every single braid on the market. Using that, you can let the cover take the abuse so the precious core fibers will be left alone.

nick, do you think the bend radius will be too great? if i have to add thimbles it would make for a difficult retreiveable set up because it will just add more clutter to tight crotches

123, im not worried about the lack of stretch, we use bull lines with very minimal stretch as is and i dont think it makes much of a difference in static loading system, im looking to use these as a rigging system for branches, not wood being shock loaded but thanks for the heads up
 
What about splicing one end with a biner (or large ring) and the other end a just a thimble? Then you could eliminate the the need for a ring on the thimble side. Nick, do you think the thimble would hold up well? :thinking

Just a thimble on one side would be less likely to snag.

not bad thinking jamin. I know that there are special thimbles for the amsteel line. They run about 23 bucks but are rated for the strength of amsteel. This may be costly for a false crotch but at least there will never be worries based on strength and if I finally learn to splice that would cut the price in half. (this isn't a bad rope to practice splicing jamin, I think we may have found our first victim unless nick says otherwise)

This thimble is only $10 for 1/2" size rope and i DARE you to bust it!!!

You just have to match up the thimble with the task. You can't use the type of thimble that you'd use on your flipline.

I'm not quite getting the value in thimbling one side but not the other. Can you explain that?

What kind of loads are we talking here? Maybe this all doesn't matter!

love
nick
 
hahaha, jamin, i thought you and i were going to tackle this together brother, wheres the team work

im going to order some up but probably stick to our original plan and get tenex first, i already have some smaller 7/16 tenex layin around so ill go ahead and ruin that first before i step into the big leagues (and big money) of the amsteel, but i am placing an order for samsons splicing kit this weeks along with a few other goodies from wesspur. nick, prepair to be battered and abused with questions, rich h if you reading this, and all you other ky boys, consider this a fair warning as well

jamin, mine as well jump on the knowledge train with me, nothing like asking nick to repeat himself mulitple times for multiple people

Loads would be good to know. What size lowering line are you using? Definitely go with thimbles. Protect the Tenex with a tube webbing as well. I have a 5/8" 3 strand rigging FC that I spliced onto steel sling rings using a 5/8" steel teardrop thimbles. Haven't had any problems retrieving it.
 
I happen to have a little over a hundred feet of 7/8" amsteel blue just sitting here, I can't decide what to do with it. Maybe some bombproof slings are in order.

What would a 7/8ths Amsteel Loopie be rated at? A LOT.

[/ QUOTE ]

7/8" Amsteel: 74,000 lbs.

7/8 Amsteel Blue: 90,800 lbs.

In loopie form I usually go 2 X 80% to calculate the breaking strength.

74,000 X 2 X 80%

90,800 X 2 X 80%

The stuff really is incredibly strong.

I would be more worried about the tree breaking than the Amsteel.

funny you say that chris, i went to a rigging seminar yesterday hosted by sherrill and that was one of the points in the seminar, its nice to have all of these stronger materials but weve reached a point where the materials are much much stronger than the objects we are rigging from, not a bad thing when in the right set of hands, but i think i would rather have a sling break than the tree limb im standing on, unless of course my ground guys are standing underneith said limb, then ill take the hit, i got that all day

thanks again mark c and bruce s for taking the time to answer ALL questions at the show

i just ordered my amsteel (actually waiting to see what toss wand i should buy, nick if your reading this check your pms) cant wait to ruin 28 dollars worth of good line
 
Good thing with the 12 strand hollow braid is if you mess up you can always just pull the splice out before you whip it tight. I've looked at one or two of my spliced and have noticed it wasn't though the middle of the fibers and had to readjust it a bit.
