I would not recommend the double overhand knot. When I tested various nacrabiners, the overhand knot did not hold more than about 600 lbf, IIRC. The lanyard knot is a bit more effort to tie, but...

I use one on either end. I'm not sure if the one on the head end is really necessary. The gap at the foot end is the problem for me.
I have had the same problem with my UQ in cold weather and use a similar method. Instead of a mini-biner, I use a velcro cable tie. It does not slide toward the suspension end and weighs a fraction...
I have used a rolled hem foot to attach noseeum baffles for my down quilts, and it works very well. Sil is a lot harder to do consistently, but can be done with practice.
I think they may be more secure as far as the knot slipping through, but I have a hard time believing they will be stronger. After playing with this method for a while, I see a potential for these to...
I made one with the larkshead. Definitely easier to make, but not by much. I think it is more difficult to use and has to be made longer than the spliced version. Will probably add 0.5g:scared:...
I have attached a figure that shows the resulting bugnet based on the dimensions. My understanding was that you want the tie outs symmetric, not asym. If this is wrong, post a quick note and I'll...
damngoat, sorry I missed this completely. I will get on it and post the bugnet dimensions soon.
That thought is disturbing indeed, especially considering what you use for insulation!:D
Are you German?
And you did this with chest hair for insulation?:D
The ridgeline makes it easy to get the hammock set up the right way every time. If you snug up the suspension to where the rigeline is just...
Hi, neighbor! What do you mean, not worrying about snow loads? We had a ton of snow in Irmo this year!
FWIW, I used to use mason line, which I believe is 150 lbf breaking strength.
I think it might be a while before I can do these tests. I have travel to Honolulu, Dallas, Madrid and Paris scheduled in April. If I can't get the tests done next week, it will be May before I can...
Maybe the concern with hard surfaces that you read about is more related to abrasion. I ran the Amsteel over 3/4" diameter steel pins. I think the hardness may not be such a concern, but the...
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...
It is a loop shackle that can be used to replace a carabiner and was posted by nacra. See this thread for details.
That is a nice euphemism to describe the excruciating pain you will experience when doing this. It works well, though.
Nacrabiner sounds good to me. I did the tests because I was a bit worried about them myself. Glad I could ease your worries at the same time.
I did not mention this, but I also tested a UCR, and...
I don't know if it will help you, but this is how I remember how to tie this knot.
1. Always go clockwise.
2. Start with the left tail and make a loop (clockwise) and bring the tail under the...
One more observation from the tensile tests: On one of the samples, I had put a short piece of heat-shrink tubing over the tails to keep them from fraying. The length of the tail was about 3/4"....
I think there is a big margin where the ultimate strength is unaffected. However, the amount of damage to the eye is affected by the balance of the legs. For the tight eye, the hole where the line...
It was a single. The Ashley and overhand were tied after splicing the ends together like nacra showed in his gallery. I am not sure you would get different results with the ends separate. Since the...
Here is a picture of the tension test setup. All samples were pulled on 3/4" pins and the knot was off to the side. The picture shows the specimen with the "cinch wind" closure mechanism by...
I made it bold, but red just looks too ugly. If possible (nacra, admins?), it would be nice to add a bold statement to the first post in this thread.
Sooner or later somebody is going to have to...
I pulled a few loop shackles in an MTS machine to get their failure load. I tested one specimen made from 3mm Lash-It and it failed at about 2,200 lbf. The remaining samples were made from 7/64"...
It takes a lot of force to turn the rope inside out. I don't think it is an issue, just close them before putting them away. Even if you manage to turn it inside out, you can turn it right-side out...
I think the 2" OD, 1.5" ID SMC descending rings used to be pretty popular before the whoopie slings. IIRC, you have to tie a backup knot when using those. The cinch buckles don't need that.
1" webbing will work, 12' for each side of the hammock is a good starting point. I like polyester much better than polypro. Are you sure you want cinch or ring buckles? All the cool kids are using...
I haven't tried it, but I think the bury might make it hard to open the loop. The beauty of these things is that it is really easy to open them up and close them. Not quite as convenient as a biner,...
I will hopefully get some tensile tests done on these before the end of the week.
I have made a bunch of them, and the lanyard knot seems the way to go right now, but we'll see what the MTS...
Opie, what kind of stopper knot did you use?
I use 24" of 7/64.
I just made one using an Ashley stopper knot. I spliced the ends together to have a single strand for the knot. It is extremely hard to set the knot and it uses more cord than the diamond knot. I...
I was thinking of splicing the ends together on one of the shackles and using an Ashley.
I don't really do spreadsheets. I did write a little program, not so much to figure out the triangle shape, but to determine the width of the bugnet that I need to cut, and then how much to cut off...
It is actually a 2D problem! The length of the ridgeline determines the baseline of the triangle. The length of the hammock fabric tells you what the two other sides add up to. If you know where the...
There is nothing magic about the formula. You need to know the length of the hammock fabric between start of bugnet and end of bugnet. That is probably somewhere between 10" and 20" shorter than the...
You could use a loop shackle to connect your whoopie sling or UCR to a loop sewn at the end of your tree strap instead of using the marlin spike hitch.
Do you want just a single overhand knot, or a double?
I will pull two shackles, one from 7/64 Amsteel and one from 3mm Lash-It, both with a diamond knot as a stopper, in an MTS machine sometime this week to get the failure load and see how/where they...
nacra mentioned he uses a lanyard knot. If you type that (or diamond knot) into wikipedia, you'll find directions on how to tie it.
If you want to add a strip of GG, you could do so while sewing the second seam line of the French seam. No additional work required. May be easier to use 3/4" GG.
I think warbonnet tarps have...
I just posted in the thread where nacra533 introduced the loop shackles. He mentioned that he was going to get some strength testing done and might be able to answer your question.
I just made one out of 7/64 Amsteel, the thing weighs 2.9g. I will try it out in the hammock suspension soon, but I have to make a tree strap with two loops in it first.
I just made one of these out of 7/64" Amsteel and now have a 2.9g (0.1oz) carabiner! The weight savings come at a bit of a price, the biner takes two hands to operate. I've been playing with it for...
I have had moisture on the quilt foot end on several occasions. The condensation is always on the outside, the inside of the footbox is dry. Using a 3/4 UQ as well. I think it is the humidity in the...
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...
I had seen that picture on the homepage one time and clicked on it, but could not really figure out what those things were for. Now it all makes sense. Very nice, have to try them some day.
I would ask the Zipper Queen.
I have used their Lycra mesh for a pad pocket and would not recommend it for an outside pocket. The polymesh from Quest is non-stretch.
