New product for Figure 9 users

[turk]

I was rethinking those new style biner Fig 9's. The only reason I would want
them would be to pitch my ENO single. But then I got rethinking the standard
ones, and they would be simple to modify for an ideal 1/8" spectra line suspension
used with the eno-1.

What do you think of this? ya I know I know ... treehuggers issue aside,
its a sleek minimalist setup and takes no time to cut down the Fig 9.
Also shaves the weight of the ENO slap straps and eliminates any biners.



btw - Warbonnet emery cloth is simply sand cloth, or grit cloth. Like sand paper, only more flexible and durable.

Turk, it looks like that 'hook' might be a little precarious and subject to being torn off. All that force might just bend it back and fail.

[schrochem]

All this figure nine stuff got me thinking.
It seems like there are a few things we'd like to accomplish.
1)lightweight with use of just a little webbing for the tree and the rest rope.
2)easily adjustable and to tie off.

Of course the lightest combination is to use tree huggers and cord with a HH lashing, but that isn't that easy to adjust.

After seeing WBGs hacked up 9, it looks like a pretty simple piece. The climbing world has stuff like that but it's for bigger ropes and is typically heavier.

Someone HAS to of tried this before but I had an idea to accomodate the list above. it would require rope, tree huggers and a biner.
Rope would come off the hammock (like the HHs have), tree huggers round the tree, a loop of cord attached to one end of the tree hugger is fed through the other end and hugger hugs tree
But somehow we need to connect the two bits of rope and make the distance from hammock to tree adjustable.
How about using a prussik or kleimheist around the hammock rope the using a biner to clip onto the loop from the tree hugger?
To adjust, you just slide the prussik up and down the hammock support rope to where you want it.
So would that hold?
Besides the "f9ss" anyone else have an idea to fill that gap to adjust length??

I don't think its going to fail. These things are way overbuilt. The tabs you wrap around in the 'W' shape are smaller.
I think in tinkering, I just proved it completely irrelevant. To use the system I have drawn in paint, you would want the strength
of the new model, gated carabiner version to prevent just what schrochem mentions.

However .... it is hard to beat WBG's previous trimmed down idea. His is simply lighter, and
serves the same purpose. The only decision that would need to be made is
if you are going to cut the eye off the Fig 9, or leave it on.
Here are some more pics to show my previous idea illustrated in paint, is really moot unless using the
new gated carabiner version.

The standard knot on the ENO single can sit in the groove behind the Fig 9 eye as in above pic.
Or you can undo it and simply thread the whole Fig 9 to the ENO 1 stock cord.


Warbonnets wrap IS the best thing I have tried so far. And his idea
of cutting off the eye entirely is certainly tempting.

Of course the lightest combination is to use tree huggers and cord with a HH lashing, but that isn't that easy to adjust.

I don't use any webbing or treehuggers... so I think that saved weight for me anyways, negates the addition of 2 F9SS

[schrochem]

That's it, I'm picking up some of the large ones tommorrow...
I just have the little ones and WBG has done that testing...

Hey Turk, starting the thread led to a VERY cool discovery, it's all good!

[warbonnetguy]

i couldn't help it, just wanted to see how light i could get it.

also switched the direction of the wrap so the load comes off the small notch, which causes the device to tilt less, and have less leverage on that joint since it's closer to the stem.

i gave it the bounce test, it was kinda scary but it's still in one piece.

the bit i used to drill the hole for the rope to go through was 9/64 i think. used a few smaller bits for the other holes on the stem.

[turk]

That is awesome!!! -- but yes scary. Easily refined though!
If you drill a series of tight holes and make a slot, you could keep a little more
meat on that one end.


Brilliant.

Now you've made me want to go pick up a scrap of plate aluminum and make
a 'T' shaped device based on your heavy mod.

[schrochem]

Hey WBG, who needs a machinist?
Heck you simplified it so much you could buy a piece of Titanium and make it yourself...

I was in bed, but the thinking kept going....
I remember seeing the Bachmann knot and the autoblock knot.
Since there would be a clip of some kind, it could work.
But I doubt it could get lighter than 8g of a hacked up 9

[warbonnetguy]

don't think any of the friction knots would work on thin line.
