Dynaglide Whoopies

[Schneiderlein]

I also notice that the specs listed on the NER website appear to be wrong; i.e., it can weigh 1.5 g/m *or* have a breaking strength of 454 kg (1000 pounds), but not both.

Why can it not weigh 1.5g/m and have a breaking strength of 454kg at the same time? The specs seam right to me.

In any case, NER (and Samson, &c.) recommend a minimum working load of 5:1 which yields, for a cord with a breaking strength of 1000, a limit of 200 assuming one *never* hangs at an angle less than 30°.

If y'all are hanging only a small distance above soft duff and don't mind a broken line then I suppose it's no big deal. I just hope no one gets hurt.

I guess everybody has to decide what they are comfortable with. I have used 1,200 lbf cord with knots for a long time without any issue. I would be very comfortable using 1,000 lbf cord in a whoopie sling.

I would like a set. I sent you an email earlier today. Maybe we can put the two orders together to save on shipping.

One might think you ought to know if you're selling it, encouraging other people to hang on it.

As I understand it, a load of 200 in a hammock strung at 30° results in a load of 200 on each line. If the hammock is strung at 20° it's 292, and at 15° it's 386. I don't know how much load might be multiplied as one tosses and turns in the hammock but HMPE is not very elastic and it efficiently transmits any shock loading to the weakest point.

That post is 2 months old.

And when I pulled a DG whoopie apart, it failed around 930 pounds. I understand the 5:1 safety margin, but that is more of a liability issue for NER and Samson than real world applications.

Thanks for your concern though.

Got it... Thank you. I dont offer the DG on my site, so if you are interested in a set, we can work the details out here or via email.

I'm interested.

If it did, its strength:weight would be about twice that of 7/64" Amsteel-Blue, for example, and certainly outside the range of all the other specifications for HMPE cordage that I've seen.

The DG I have weighs 2 grams per meter.

I witnessed someone hang from it at over 300 and I am a believer. It is truly amazing.

I was there and it is true. I myself hung from 7/64 dynaglide the same night and I weigh in just over 200 lbs. This stuff it tough.

Did you mean 7/64 dynaglide? Is there such?

Opie im considering making some, what would you say the weight savings are vs 7/64 amsteel at 9 foot lengths? just a guess would suffice. BTW do you remember how big the dg we did in the group buy was, was it 7/64, cause if so, thats what i have, in orange.
