i haven't hung overnight, but it seems super easy to release, just pull the plates apart.

here's something i made awile back, but it didn't hold with the amsteel blue so i set them aside, then i tried with some vectran the other day and it works great, they adjust smooth, and self align...

try using the alternate wrap from early in this thread, it might work better, the nine wrap works because it has a really narrow notch to pinch the line and teeth, yours looked like it had neither.

just a thought, if the webbing part is a pain to adjust and most adjustment is still made by hitching the hook, why not just make one with only one slot instead of three, you would simply thread the...

you could take the blade off the hacksaw and reassemble it with it inside the alum.

it is somewhere on this thread. somewhere not too far before my 4g. anchor plate.(i made a couple, the 4g was the lightest and last.)

Rapt "the engineer" made a anchor design that came along with a calculated breaking strength based on the alum alloy (look and see which one, not sure) and 3/16" stock. he even made it so you could...

the large origional nine(not the biner nine) weighs about an ounce as is. after my final mod, it weighed 7g i believe. however, all the work involved in the mod was about as much as making one of the...

the large is the one that i cut down and filed the teeth off of. once the teeth are gone you have to use the "new" hitch as well, as the fig nine hitch(the one on the package) will not hold without...

here's my post from another thread.

yeah, the silicone seems to hold up well. i don't just dip it though or even coat it. more like impregnated i guess.

i dab a small amount on my finger, then i smear it into the end of the line...

cool, that was my concern, that it would not tighten with a pull on the free end, but sounds like if the hammock is unweighted, it should work. it holds well with uncovered spectra too, thats what...

dutch, how easy is the hex stock adjuster to adjust? looks harder than with rapt's 2 piece adjuster. can you just pull to tighten, or do you have to feed the line through the holes?

but in a way, were not really reducing weight at all. a knot is the lightest option. we're just trying to add the convenience of mechanical adjustability without the higher weight penalty associated...

it's for convenience and weight. the convenience of biners, without so much weight penalty.

that's a good idea. it reminds me of the public bathrooms with no doors at the entrance. like the ones at the airport. you could call it the bathroom buckle.:)

by far the coolest thing to do would be to install a wire gate on it. if you've ever looked at a wire gate, it doesn't look like it's that complicated(alot less complicated than a regular gate)....

so you could have this biner replacement on one end of the webbing, then rapt's 2 piece device on the other, then line coming from the hammock to the adjustment device.

just wrap the tree and...

how much is the buckle by itself. (you forgot to weigh it before you attached it didn't you) how much webbing is there in the strap?

looks good though. much lighter than a biner.

you could jam...

i thought that was what was going on, might as well reduce the pole compression whenever you can. probably helps stability as well.

cool, so you are adjusting the size of the triangle and the "sag" adjustment at the same time? as the trees get farther apart, the triangle just gets longer and longer?

long live the fig 9 thread.

every knott is easier than the hh lashing:D

grizz, just use stock aluminum and make it the dimensions you need.

what's up fellas? just got home last night. good to be back.

nice work Dutch. 900# and still intact. very re assuring indeed. remember dutch, about the vectrus 12, a 2000# rope tied with a knot...

remember what rapt said about safe working loads generally being 1/3 to 1/5 of the actual min. breaking strength.

600# working load could mean 3000# break strength. seems like with biners, the...

wow. i would have thought those steel quick links would be heavier.

yeah, i was thinking more along the lines of a biner without a gate. like the letter C or the #6 or a fish hook shape.

hey scott,
that black diamond keychain biner of mine weighs 26g, which is only a couple grams lighter than an ultralite full strength one. both of which have to be lighter than a steel quick link....

turk, looks like you could lift a truck with that thing.

scott, there has to be some lighter biners out there. they probably aren't rated though. like the one turk has, although i haven't seen it...

those look great. they almost look like they were not made by hand. what tools did you use. i really like the 2 holed thing with the single hook. there was discussion about making one of those a few...

i know this is so last week, but i made it anyway.

this one is based on rapt's cad file. just made the stem a hair longer and the hooks shorter.

thanks to scott for the 3/16" alum, which was...

pretty cool turk, interesting idea turning the nine into a webbing buckle.

what advantage does that have over just having a sewn loop on each end of the webbing and threading one loop through the...

sounds like fun. i'm anxious to hear what happens.

i had to go out of town for work, as i will next week too. no internet access at the motel 6:(

wow, y'all have been busy. alot has happened in 4 days.

dutch, did you ever test the large 9 to failure?

so a half hour to cut 1 piece?

so is the "cad file" what is needed to run a plasma or water jet cutter?

if so, i bet the cost of having them made would be alot cheaper if the machine company didn't have to write up the file for...

Rapt,
thats amazing how you can do that and calculate the strength based on dimensions and type of metal!

looks like a stem that short is gonna have alot of tilt, and need steeper hooks. the...

just got back from colorado iron and metal. i had to choose between 1/8 and 1/4. they didn't have 3/16. i got one foot of the 1/4". i figure i can make the device narrower since it will be thicker....

you are the man dutch.

that is awesome. did my wrap slip too? the one in the top pic looks different than mine. i did figure it would eventually slip with enough weight though.

so, a stem made...

yeah basically, device is permenently attatched to one loop of a tree strap via the shortest piece of line you can use. support line is attatched to the hammock like normal, and is "tied" to the...

ok, just seemed too light to be true, but i'll take your word for it.

you need to get some 3mm~1/8" vectrus 12. rated to 2000#. very thin, very strong, and handles superbly, and probably alot...

hey dutch, if you used softer line like uncovered vectran or spectra it might work a little better than the covered does in those small holes.

are you sure your scale is right? that thing looks...

a hacksaw blade with fine teeth works good for cutting. a vise was helpful for holding it. a bench grinder and/or a file is good for final shaping. i bet you would be less accurate with a jig saw...

i wish i hadn't drilled those small holes yet, b/c now i can't really shave much more weight off the bottom portion. :(

i would be more motivated to see how light i can get it but i don't think...

ok, i had a better one partially made, so i went ahead and finished it.

it's 1/8" thick, and the stem distance (length between where the short rope attaches(very top of the big hole) and the...

from my destroying the mini 9's, the failure will probably occur by the hook that the weighted end hangs off of will tear from the stem. the only problem is that the hook which holds the weighted...

hey dutch, since you've got the time and the tools, here's what i have been trying to find time to make.

i was gonna use 3/16" since it is has open hooks, and that's what the fig. 9 uses, i made...

well i hung from the small 9. rated to 50#. i hung the hammock with moderate sag, and i weigh 160. this means just me in the hammock was likely putting double my bodyweight or more on the device....

right, and the load on a device used for hanging a hammock would be much less than the minimum breaking strength as well. if the fig nine has a safe working load of 150#, the min breaking strength...

2g are you kidding, thats almost weightless!

remember forces on a tightly hung hammock may exert 2 even 3? times your bodyweight on such a device. you should test in the actual application, with...

climbers load biners hundrerds of times, i've never heard of trashing them after a certain number of falls or bodyweight loadings, only when they get too grooved out.

not familiar with where to...
