Soft Halyard or Line Shackle

I bought that scale for $25, how could it be inaccurate? ;-)

I have a new idea; using something like a whoopee sling to make a cascading adjustable shroud with those new fangled friction rings, which would allow the whoppe sling splice part of it to only carry half the load, and use a bungee cord in the same way as the Constrictor jam cleat.

I will mock one up with my tiny line ('cause I'm too cheap to use big line) and break a couple of them and see what happens there.

If you are interested, I could try to do another test of the luggage tag with extra diamond knots using a stronger shackle to see what it takes to break it.

PS, please link to the new thread...

Is it possible for you to make a conventional soft shackle and break it to see if your results are calibrated to others? It should break at 125% of line strength plus or minus. If it is breaking at 200% of line strength, then we know what is going on.

Yes, next time I am doing some testing, I will make up a soft shackle with only one knot and see what I get. I will also pull the one I already made and see if I can make it break. I could also make another one with multiple knots and see if that is the same too.

But you will also have ot take a look at mey new idea and tell me what you think ;-)

Hi again,
Let's just back up a bit. We have a lovely new configuration, which I will tentatively call an Inverse Otto, that wants testing. So far, our intrepid inventor has, with a minimum of equipment and a lot of enthusiasm, demonstrated that it shows promise. There are variables to be dealt with: multiple vs. single lanyard knots; tapers in the splices; actual strength of the materials; how much load comes where; and maybe especially how accurate the machinery is. So I urge you to send some samples in, configured any way you like, for our Extravaganza. You get free breaks, courtesy of Treestuff, plus enduring fame.
Fair leads,
Brion Toss

Oh, I like that. When is the deadline, and where do I send them?

Ping me off list if you want.

PS I would like to call it the Flexible Anton Soft Shroud Inadvisable Attachment.
