View Full Version : Dynaglide Whoopies
Anyone interested in some? These will only be for folks 250# or less.
I dont have alot, but its all orange. Maybe enough for 10 sets of 6' slings.
Price will be the same as the Amsteel. $17.55 shipped.

I put these on one of my DIY jobbers. I doubled wrapped the larks head. Held up my 270#. Now granted, my basement hammock is hung at more than 30 degrees... So I bounced in it pretty good... Till the ceiling started creaking and it sounded like my joist support were going to break.
The last shot is of the adjustable bury exit after I loaded the sling up.
In case anyone missed it, I did do a destruct on the Dynaglide whoopie and through my figures it failed at around 900 pounds.
Oh yeah.. and weight on a pair is 18 grams, or .6 ounces.

Hey opie, what the bury length for the dynaglide?
Cajun, I keept the buries at 6" for the fixed eye and 9" for the adjustable.

Thank you sir.
Welcome.
Message to short.
I thought for sure someone would want a set of these ultralight bad boys.
If for nothing else, bragging rights.
How about I drop the price to $16 shipped.

Dude, that is just wicked crazy!
I just never could find the math acceptable in my head (I tend to like lower angle sets). Strangely, I have been hesitant to touch the last of my stock, perhaps silently waiting to gain the "fortitude" to try a set of DG whoopies on my Hyperlite. Whoopies are about the only thing I haven't tooled up with my DG.
If we can tool up some sort of "safety catch" as a secondary in case the line at the exit point fails, I think we could call this a new knotless lightweight best.
Trail, the DG whoopie I tested gave out at 930 pounds.
I forget what the formula is... But wouldnt a 200 pound person need to be hanging around 5-10 degrees in order to approach the limit?
And whos hammock is hanging at less than 20 when its loaded?
Anyway.. Thats why I put a weight limit on it.

930# inline static tensile failure?
930# failure in a whoopie sling. Failed at the exit of the adjustable bury.

What diameter is this my friend?
WarmSoda
03-11-2010, 11:56
http://wesspur.com/throw-line/zing-it-throw-line.html lists dynaglide as 1.8mm and 1000 lb tensile strength.

03-11-2010, 12:28
That just seems too small of a diameter to be hanging from,does other people feel the sme?but at a 1000lb breaking strain it has to be safe for my measly 200lb.

I witnessed someone hang from it at over 300 and I am a believer. It is truly amazing.
What diameter is this my friend?
I think there are different diameters of dynaglide. The stuff I'm using is 2 or 2.2mm. Either that or there is a bit of disinformation out there on the diameters of the dynaglide.
I was skeptical too, but it will hold the average hanger. I'm 270 and it holds me both in a gathered end hammock and my bridge.

I am reading all this info on suspesion and trying to take it in too quickly i think.
firstly what is the difference between Dynaglide, zing-it , and lash -it.
Would they all do the same jobs and can you make whoopie slings from them all?
Would i be better to make whoopie slings as opposeded to a double fishermans knot?
So many choices and decisisons ,but this kit is not easy to get in the Uk ,so i want to get the right thing.

Lash it and zing it are the same thing. Lash it is gray and zing it is yellow. They both come in 1.75 & 2.2 mm versions. Yes it is spliceable, but I wouldn't reccomend it for suspension. They are made from dyneema fibers just like Amsteel.
Dynaglide is a another version of the Dyneema fiber, but pre stretched. It's also a 12 strand where the zing it and lash it are 8 strand.
The whoopie and double fishermans knot do not sere the same purpose. The double fish knot is good for making a loop of cord, or joining two lengths of rope. The whoopie sling is an adjustable length of rope that locks under tension at the length you leave it at.

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.
I also notice that the specs listed on the NER website (http://www.neropes.com/product.aspx?mid=AD5A655BCA5BFA2A6B340F8F4F462C5D&lid=3&pid=94) 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.
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. :)

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.

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.

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.

Why can it not weigh 1.5g/m and have a breaking strength of 454kg at the same time?
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.

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.

I got my set in and added it to my Nano hammock to try and get the weight down for my SUL thing. 18 grams for two 6' slings and it holds great. I added some 550 cord shell where it goes through the gathered ends of the hammock to help prevent any chance of the line sawing through the hammock.
Thanks opie, they are great. About the only thing I would think about changing is see if they could be even shorter than 6'.
Albert Skye

To be clear, I have no axe to grind here; I'm simply giving notice for those who might be unaware.
So, lets put 300 in the hammock. Now assume, for whatever reason, that it gets hung at 20° instead of the recommended 30°. That gives a *static* load of 439 on each side.
It's easier to bounce a bit when moving around (changing position, adjusting bedding, &c.), especially with so much weight. This *dynamic* loading can be more or less, but lets call it double: a static load of 300 becomes 600 in dynamic loading, 877 on each side.
Dynaglide (http://www.neropes.com/Datasheets/ARB_dynaglide.pdf) (*when new*) has an *average* breaking strength of 1000 but *minimum* breaking strength is 90%. Assuming the cord has no defects and uses only careful splices (no knots, marlin spike hitches, or other sharp bends), breaking strength is further reduced by 80% for a Whoopie Sling according to Samson but lets say it's as good as 95% anyway: an average breaking strength of 1000 yields a minimum of 900 with splice reduction to 855.
877 > 855
There are many reasons (not just liability) to use a significant safety factor.
In any case, do as you will; it's good to test things! ;)

SGT Rock
03-25-2010, 14:34
The hammock I currently have these on is a gathered end so I just passed the end through the channel then ran the whoopie sling back through the eye it has. I guess that means fixed eye? I plan to take some pictures of my set up today if the rain cooperates.

I have two types of line that I use most, 7/64" amsteel and dynaglide from the group buy. They are definitely not the same diameter. 7/64" is 2.78 mm. I thought the dynaglide was 2.2 mm.
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.

The Dynaglide is 2mm, while the 7/64 Amsteel is 2.5mm, or therabouts.

It should be 2mm. Some vendors have it labeled as 1.8mm. But I believe its all 2mm.

My safety factor is a 250 pound limit. I.E. I wont sell them to you if you weigh more. I believe this is in the first post of this thread.
So far what Im getting for an average weight is 150# for folks that purchase the DG for slings.
Again, thanks for your concern.

Should be, yes.
Just went back and looked at the group buy listing and Opie did list it as 2 mm. Not sure where I got the 7/64 number from. This stuff is even smaller and tougher than I thought.

That post is 2 months old. ;) And this newer one seems to imply a 300 pound limit.
Anyway, replacing 300 with 250 in my previous illustration brings the load on each line to 731, and if we *do* use Samson's 80% reduction for Whoopie Slings, minimum breaking strength is 720.

Yes.. I said 300 in the post you just linked to. My mistake. I stand by 250.
720 is well below the 930 the ones I tested failed at.
You must keep in mind the minimum breaking strength that manufacturers put out is very conservative. For liability reasons.
Much the same reason I put a 250 limit on a DG sling, for liability reasons.
Then there is the real world result of a set of DG slings holding me up... 265#, bouncing around creating dynamic loading. They have held me in both a DIY and a BMBH.
While I agree with you that a certain amount of common sense must be put into place when pushing the design limits of a given product. Please dont assume I havent given proper thought to offering those products for sale. Everything I sell I have tested. Not just with me physically trying them out, but also pulling them apart. Yes sometimes things get past me like the original toggled TRL where the line toggle was to short.
It appears that most of the folks that have replied to this thread are all under 200. Closer to 150.
Im bad at math, can you do your calcs using what the actual weights are of the members using them?;)

In your previous post, you also assume that you hang at an angle of 20º and that you can double the load by a bit of bouncing. The minimum breaking strength of 720 lbf you assume now is at odds with opie's testing.
From what I have read here on HF, and from my personal experience, a lot of people have used ropes with breaking strengths between 1,000 and 2,000 lbf for a long time. And everybody, including myself, used some sort of knot before splicing became all the rage. I am convinced that these suspensions had a lot lower failure loads than the Dynaglide whoopies due to all the knots that were used.

Much the same reason I put a 250 limit on a DG sling, for liability reasons.
And when it comes to customers like me (and I imagine some others here) - when I order something like this I understand there is no warranty given or implied. It's pushing the limits, so I take a chance I could brake a sling and fall 18" on my ***. It wouldn't be the first time. It isn't like I am going to hang over the Grand Canyon with one.

SGT.... Glad you are happy with them.
If you want them shorter, you can pull the tail out until the sling length is where you want it, and then cut off the excess. You'll need to tie a stopper knot in the end of the tail so it doesn't accidentally disappear on you.
Also... Im all out of DG. My intention in offering these was to use up my supply. I wont be restocking but will make them special order.

Cut them! Eeeeekkk!:scared:
I won't do that until I've hung with them a couple of dozen times in the field and make sure I don't need the extra length. Really, at 18 grams for the pair, I think I can hack the weight.

LOL!! Yeah.. they are light.
The only thing I noticed.. and the lighter folks may not... But the DG has a vinyl coating on it. After the bury gets loaded overnight, its almost like the vinyl sticks to itself in the bury. Not difficult to release, just different than the Amsteel Blue.

Yes.... My first generation of guy lines was a UCR based system. Works well for a guy line... But in a UCR for suspension, where you need to back up the tail.... The line is already so small its difficult to get a prusik to lock on it. Possible, yes. But its pushing the limits, IMO.
And the DG sling is already pushing the limits.

For 150 (just halve the original example for 300): 438

The minimum breaking strength of 720 lbf you assume now is at odds with opie's testing.
I know it's at odds with the claim but I know nothing of the actual testing (i.e., how it was derived). I'd be happy to see the results if you're interested in doing more testing. Thanks for testing the soft shackles, by the way. :)
I'm particularly interested to see how HMPE compares to steel in fundamental D:d strength (http://practicalmaintenance.net/?p=576). All of the manufacturers that I've communicated with said they have not done that testing but I was told to expect it to be weaker in bends than steel.
I am convinced that these suspensions had a lot lower failure loads than the Dynaglide whoopies due to all the knots that were used.
Indeed, HMPE is especially vulnerable to knots.

Ok tonight i used 2 17 ft sections of dynaglide to make locked brummel whoppie slings. My only concern right now is abrasion on the hammock fabric, im thinking of wrapping ductape around the fabric to prevent it, have seen the tubes, but currently have no access to them. those of you who have hung with these, please let me know your results with abrasion as well. I will hang tonight with them on and report back tomorrow what happened. I will be using my hammock stand, so the angles will be a little sharper than 30, maybe 20 or 15, so the strain will be stronger. i weigh 150. BTW its REALLY scary seeing that tiny line suspending you, but if it works, i will never go back. Also thinking of replacing my WBBB ridgeline with it if it works out good. Shave off as much weight as i can! lovin it! =P

I slid mine through the 550 cord with the fixed eye which is as wide as two sections of cord, Even with a brummel I think it would be possible. Or maybe I just ain't visualizing it right.

Opie told me to jusy wrap the brummel around the hammock fabric head as well, so im just gonna do that. Figure it will distribute the pressure more evenly. Once they were made, its impossible to attach any paracord. I will on my next pair i will make tonight however. I love making these things!

Ike, after you make your sling, just slip the paracord sheath over it and leave enough room to run the sling through the fixed eye. It doesnt matter if this too gets wrapped up in the larkshead.
SGT. added his after they were made. All it will be is a sleeve.

Opie I'm abit confused about what u mean. Hang went great, nofalls or anything. Gonna replace rifgeline soon as well

I can't get my sleeve over the line, the paracord breaks apart and theres no way to force it down the tube, it isnt stiff enough.

What I did was use a piece of the inside string to pull the dynaglide sling through. It wasn't easy, but it could be done. One side played nice and I finished it in about a minute. The other took about 10 minutes.

ok so what i ended up doing was putting the loop that connects to the blackbird fabric bundle through a 4 inch piece of hollow paracord. Once it was slightly in i used my needle that i use to make whoppie slings to puch it through the tube. Minor damange to the sling from using the rounded metal head( i did not use the sharp needle part to do it). Now i have a section of paracord that i can slide up and down the line, i cannot cover the loop because i need some of it exposed in order to wrap around the fabric bundle. I had to burn the edge of the paracor on each side to keep it from fraying.

I guess with this sheath, there is no need to double wrap the line around the bundle.

On my "normal" hammock I wrap the dynaglide around the whipping rope.

I got some of that 1.8mm stuff in to make a bear bag rope. I tried making a whoopie sling out of some - man opie, you must use a microscope when working with this stuff.
I was blessed with good vision. Although after a couple hours, it does get old.

I wore out the bottoms of my bifocals. You deserve whatever you make doing these things.

just put five nights and a day of lounging around on my DG whoopies... not a sign of wear, no slippage, no abrasion on the hammock larksheaded directly on the fabric. i weigh 170#. after using the DG ridgeline i've decided it's indispensable. just a great product. i'd say with my gear in there i'm pushing towards its limitations and it takes it just fine

I got a blister on my right index finger.
My first cut-off adjustable hammock had twenty strings on each end attaching to the main amsteel whoopie line. Each string was 130 lb. test spectra fishing line with a tiny little adjustable whoopie. :scared: My second hammock used the same type of suspension. :scared::scared::scared: ... :lol: This is not an April fool's joke.

I noticed it a little just playing with them today.
Have you tried making UCRs out of this stuff?
Yes.... My first generation of guy lines was a UCR based system. Works well for a guy line... But in a UCR for suspension, where you need to back up the tail.... The line is already so small its difficult to get a prusik to lock on it. Possible, yes. But its pushing the limits, IMO.
And the DG sling is already pushing the limits.
I've proved you right on those Dynaglide UCRs. My experimental set have a tough time locking in. Sometime I think it is good but when I get in the hammock I find out the hard way I wasn't.
Dynaglide UCRs = Not so good.
Rock... Double the length of the bury, or at least add 50%.
Then, prior to loading the suspension, milk the bury down tight. The UCR will hold without a back-up. You just need copius amounts of bury.

I gave it about 10". Where my issue lays is milking the bury back enough to hold. Even times when I think I have it right I can be wrong. If I get it right it holds tight, but if I am just a little off about the time I swing my feet over into the hammock I get a slllliiiidddeee to the ground.:scared:

Add another 4" or so.

I may try making another set and do that. Thanks!:cool:
SGT... this is going to add weight... but you could fashion a loop in the end of the constrictor and add a piece of shockcord and run that back to your straps. This would back up the constrictor and not add a whole bunch of weight.

Actually I have thought about that.
It doesnt neet to be monster SC. All it need to do is add a little bit of tension to the backside.
OK... I have some DG back in stock.... For the UL crowd.
Reminder... You must be 250# or less.

Hmmm
I would quite like a set of dynaglide suspension whoopies for my DIY bridge, I weigh less than 12 stone, 168 lbs so no worries on the weight. However I use a fixed length cord attached to both which not only helps me get a good hang angle but also is what I will hang my midge netting and tarp from.
I'll work out some dimensions and shoot you an email, probably along with a sketch so you can understand my babbling :lol:

Opie,
How long is the bury on these 10in? Or are you making it longer?

Sarge, why are you using ucr's instead of whoppies? Don't you think they are finicky? My dyna whoppies made with 17 foot of dynaglide 2.2 each only weigh like .4oz anyway. Thoughts?

A UCR with the dead end doubled back to the hammock (picture both end of the UCR attached to the hammock, thus forming a *******ized whoopie sling) woulld reduce the strain on the week point in the system by 50%. Not that I loop mine back though... :rolleyes:

Sorry about the poor quality pics. :( It was low light in the back yard last night and all I had at the time was my phone... Maybe I'll edit the post later if I can swipe my wife's digital. ;)
Its a weird feeling crawling into your hammock hanging from DG for the first time....
I had an air mattress under me the first time.

Just playing with things. I got a bunch of that stuff and made me some 4' whoopies instead of cutting the professionally built ones from opie. Once I mastered that I decided to try making some UCRs. And yes, they are finicky. Most likely I will convert my "normal" hammock back to whoopies. I'm using whoopies on my SUL Nano 7.
One thing is I wish they were called something besides whoopies. Sounds so girly when I try to explain them to non-hammockers.
