Question - Amsteel Blue

[MasterBlaster]

Has anyone ever used it for rigging in the tree?

 

[No_Bivy]

just for a high line...

 

[MasterBlaster]

How well can knots be tied?

 

[lumberjack]

They can be tied fine, but you'll kill the tensile strength of the rope, down to the point where it'd make more sense to just use a poly rope. They are also prone to creep due to it's slippery nature.

 

[MasterBlaster]

Ooops, I just read "knotting severely reduces Amsteel."

:what:

 

[No_Bivy]

I have a splice in one end...then use a double bowline on a bight on the other. Knots could get welded if you taint careful

 

[lumberjack]

You can use a porty and lock it off just fine. Technically that may be a knot, but knot in the traditional sense.

What are you thinking about? In some applications you can add wraps or other friction makers to make knotting a possibility.

 

[MasterBlaster]

What are you thinking about?

Using it as a lightweight, super strong bullrope.

 

[lumberjack]

Ah, bad there also. Amsteel will melt really really easily.

Works dandy for pulling trees though.

 

[MasterBlaster]

Hmmmm. I see. I could still use it for that. I've an employer that swears by cable for pulling, I'm tired of dealing with all that weight. I'll set a pulley and a groundie will pull it up to me. Amsteel seems like a much (though expensive and {chainsaw} delicate) alternative.

 

[lumberjack]

Amsteel is fairly close to the same strength for the same diameter of steel, but 7 times lighter.

I have a 1/2" rope with a 3/8" core (cover protects core) that is good for 21-22klbs, no stretch, like cable. Also, if it happens to break, it simply falls to the ground, not slingshotting back at lethal speeds.

 

[MasterBlaster]

Lordy, how many have you broke?

 

[woodworkingboy]

MB, what are you pulling with? I'm thinking not hand pulling if the employer uses cable.

 

[lumberjack]

Never broke that line, have broke Black Widow (1/4" Amsteel), but not doing tree work.

 

[MasterBlaster]

The guy uses a skidder to pull.

 

[Treeslayer]

Never broke that line, have broke Black Widow (1/4" Amsteel), but not doing tree work.

I thought black widow is kevlar? I have one, the 180' flat rope. we run the lab puppy on the beach with it.

 

[lumberjack]

Nope. Black widow is just renamed skinny Amsteel, made from Dyneema, which melts at 305*F or less.

Dyneema is slick, kevlar isn't as friendly to the hands.

Kinda an expensive rope to use as a dog run eh?

Butch, HMWPE lines are not for rigging in a tree. There is near zero stretch. Like Carl, I do have a double braid line with spectra core. As long as the loads are light and there's no shock loading...as in lifting or lowering a pretensioned load, it would be alright to use. Otherwise, the tree or sling/block could be shockloaded...not good.

That said, I have 600 feet of 24,000 # 1/2 inch spectra and want to sell up to half of it......$1.50 a foot...retail is about 2.50.

 

[lumberjack]

The only thing I use my 1/2" Validator II for is with the GRCS to pull trees over or lift big nuggets.

 

[MasterBlaster]

No stretch, good to know.

we have a strong current where we take the dog, and my daughter's afraid to lose her puppy, so, she gets what she wants, I spoil that girl.

 

[rbtree]

Better keep her away from da lumberjack then.....

 

[tntree]

I have 300' of 1/2" for sale. Only used twice at ISA human zipline events.

about 1/2 price

 

[rbtree]

pfsstttt...

Yo Dave...I offered mine first.....

same stuff, but PSRopes........

Actually, I've offered it several times on a few boards.....

 

[tntree]

oops, sorry. Samson Donated this to our local ISA chapter at the 06 convention in Mpls. no takers on this here either ~ spendy stuff even at 1/2 price
