One inch Amsteel that NickfromWI spliced for crane

Re: One inch Amsteel that NickfromWI spliced for c

Maybe I'm partial, but, cool thread! That was a fun project, David. I was about to express order some whipping twine fat enough to be good for rope that size...then it hit me!

Maybe you can post a zoomed in pic of the whipping twine???

How's the knotting capability with the Amsteel, do they slip more readily than Stable Braid?

There are 2 ways to answer this question. There's the "in the field, the way it'll probably get used most" answer- which has been answered already. Then there's the, "what happens if you push it to the max" answer.

If you tie a bowline (or any other knot, I'd bet) and pull on it to see how high it breaks- the knot in amsteel (and any dyneema rope) will come undone before the rope breaks. On the molecular level, the fibers are SUPER slippery. In a manner of speaking, these ropes shouldn't be used with knots.

But the truth of the matter is that even 3/8 amsteel has a breaking strength of like 19,000 pounds. Tree guys are not loading up the rope with the few thousand pounds it would take to get the knot to slip.

This might be an indication that in many instances, people are rigging with lines that are way stronger than they need be. They might be just as well off with polyester.

Who knows.

Thank you for the kind words. Now if you'll excuse me, I've got some bungee footlock prusiks to make. NeTree, your ropes on the way!

Re: One inch Amsteel that NickfromWI spliced for c

okay, sure will. Nick made it out of the same stuff. one throw line thread is made of amsteel and that's what he used.

it's in my crane tool box, so I'll take a picture Sunday, gotta get up early and watch MattyD at a woodsman college competition tomorrow. better get to bed.........

I'll jump to the fat picks.... can post others later if you care..

2 picks with the trunk? Interesting. Could the K-boom technically make that in one pick? I'm guessing you needed to do 2 for space issues while loading the truck.

Nick. Can you explain a little more what you mean? Thanks.
 
Re: One inch Amsteel that NickfromWI spliced for c

Jamin- the ropes is slippery. Though it can get fuzzed up...the parts that make up the rope are just very smooth and don't hold onto eachother well. Not only that, the fibers are often lubricated while being made so that they will work together better.

In break tests, knots typically untie themselves, rather than the rope actually breaking.

Let me know which part isn't clear and I'll try to put it a different way. The internet can be difficult sometimes!

my idea to insure the one sling doesn't come off...

[/ QUOTE ]

This looks like a very secure way to keep the sling in place, but I think there is a significant downside. Where either sling emerges from the saw kerf, it crosses a very sharp edge. The lateral forces on the sling will be many times higher at such a point than anywhere around the bark-covered surface of the pick. This will be a weak point and a wear point. The tension in the sling may be well below the published WLL, but the rope was never intended to work hard around sharp edges, and there may be little or no data on the consequences of using it that way.

well, great, here is some data on the consequences of using it that way:

it isn't a problem to be concerned with at all; with slings that are more than adequate with these weight loads. just for size comparison, that little blue amsteel sling as the backup was 1/2".

not even a slight amount of wear occurs.

thanks for your concern.

Man do I miss that truck.

What is going on with that one cut?

[/ QUOTE ]

what cuttenwolf says he is referring to here; is the cut I'm making from the truck. i figured more would jump on this picture.

I was using an ms 880 (heavy son of a gun) to make these big cuts.

I used a ladder and lanyards to make the majority of the cut. Very tiring and actually my shoulders suffered pain for almost two weeks afterwards (getting old I guess). I finished the final cut (just a little strap) from the truck (which was nice and stable and actually easy on my shoulders). Dispite the look in the picture, this felt much more stable and secure. I honestly felt I was never unsafe working on the truck.

I thought it looked like in the picture that I was a little unstable, but I really wasn't, so I posted it despite what I might hear on here. Because in the real world, every picture won't appear like perfect safety.

Ain't they heavy though. We replaced our husky 3120 with a Stihl ms880 and I miss the 3120. The 880 beats the hell out me, the 3120 didn't.

That must have sucked BIG time using an 880 on a ladder. How old are you? I'm 36 and the 880 whoops me when flushing large stumps. Oh yeah, I'm not soft

I'm 35.

the crane has been making me weaker.

Here's another maple. simple tree removal. tree was topped by someone before. spider leg pictures with Nick's amsteel.

Re: One inch Amsteel that NickfromWI spliced for c

all of these have been taken with my samsung phone by the way, it does pretty good for a phone, and the fish-eye lens helps get more in the picture.

up in the tree, amsteel up close

Re: One inch Amsteel that NickfromWI spliced for c

Nick, I noticed you did a straight bury for these slings. Would there have been a downside to using a locking brummel instead? Or is there a reason you spliced it the way you did?

I'm just curious about how Amsteel, with the low melting point, would handle a locking brummel.
 
Re: One inch Amsteel that NickfromWI spliced for c

The concern here isn't the melting point- it's the desire to prevent tight turns. Dyneema isn't a fan of tight turns/bends and the lock of the brummell involves tightness.

In this situation, I saw no reason to stray from the manufacturer's recommendations. I stitched 'em good, just in case!! (with zing-it)

Xman- those are AWESOME pics from the phone. I might have to use 1 or 2 of them!!!
