Moss Cinching Lanyard prototype

[moss]

A good name for your earlier prototype would be The Saddle. Wichard uses a similar shaped horn for one of their soft shackle connectors. It sure would be fast on and off, but don't see a way to retrieve it.

The retrievable part is a bit of a gimmick, I've never looked for a retrievable in a positioning lanyard but if it's needed 1% of the time it's nice to have it ;-)

This is a drawing i did before I built the F8 prototype . . .

This is positively lovely. I wonder how strong one of these would be if I whittled up a pattern and cast some for us in aluminium? It would need to be about 1/2 inch in section everywhere and of course would still never really be considered life support. Too easy to have hidden casting flaws. A casting in aluminium is never as strong and trustworthy as a piece CNC'd out of the solid. But I think it might work fine for lanyards if one was careful to always be tied in twice as much as possible as one moved up.

Thank you! It needs to be life support quality, at least I expect that out of my lanyards. At some point i’ll try and build a 3D file and cost getting something milled.

Moss, would it be ok to switch out the aluminum carabiner for an oval steel one and continue using as you were?

Steel carabiner is solid choice for a cinch for sure.

I just tried out something different for choking my lanyard that is easy to do, chokes easier than my last configuration and seems like a great option for not cross loading. Please let me know if I'm putting forces on my lanyard snap that I shouldn't. View attachment 54973

This also allows for a versatile lanyard setup.View attachment 54974View attachment 54975View attachment 54976

A steel circle is mighty strong, looks good.

I know you folks know this but it has to be said, I have opinions but every climber has to decide for themselves what is safe and what isn’t.

Love Andrews sketch. It makes me think that if the hook part stuck out more like a grapple, it would work as one also. But perhaps it is better to have a purpose built tool for each use.

Here’s a new one, reducing the small ring end to just horns, passes the shake and wiggle test, size is close to a carabiner.

If you want to go to a smaller circle, these three will work using the smaller circle. The bottom one is the biggest and is their latest model.

That is beautiful. Get me one on the end of my rigging line for blocking down a spar.

Did a very tricky prune today. After two days on the F8 lanyard today I went back to my regular lanyard. When things get edgy, and it was for the major part of the job, I’m more comfortable with my regular system. I’m beginning to think my F8 lanyard will be my rec lanyard when i’m not pushing the limits.

Interesting. The fate seemed to have promise. What had you questioning/reevaluating it for production work?

Today I was in a situation where I needed a quick attach one-handed lanyard cinch that could quickly slide up. Long story, delicate perch on the top of a big upward curved partially hollow cracked limb. I only had horizontal and at the extreme less than horizontal support from my main rope. Everything worked out but the F8 lanyard was not right for the scenario. Not giving up but recognizing some drawbacks for some situations where attachments need to be clean and quicker than usual.

Splice a ring into the eye of the Lanyard, or use a Ring-Open (Petzl, Edelrid, etc...) in an existing eye. Flip the Ring/Eye around the tree part, pass a bight of the standing end into the ring and spike with the carabiner. Auto cinch, easy removal, no thimble prusik required.

I like it Eric! With a horn on the ring one less piece of gear but sometimes the best solution is a minor compromise worth making. Any rings hanging around my shop bench are now in danger of being sewed on to the end of a lanyard ;-)

I don't think anyone has mentioned there smc mini 8 (escape 8) here yet. Possibly good shape. Maybe not rated to preference.



I recall there was a mini totem, but maybe it was a prototype or I'm imagining.

My buddy Josh was talking about a ring on his lanyard when these things came out. I kind of like the idea of being able to just slap it in until it holds.

I could see the bight on the ring slipping and becoming a girth hitch. Ears on 8's were developed to eliminate this possibility. The mini 8 above looks like a good choice.

 

[Brocky]

A downside of using the escape eights in this application is the thin construction, with a small bend radius.

Yep, radius profile not good.

When the 8 is on an eye completely different configuration, there’s no potential to slip to a girth, the ears would get in the way of the desired functionality.

But... Ocean’s ring end idea led me to yet another solution, your eyes will pop with amazement! Ha, we’ll see, need to build it next couple of days. Hint, it will involve an X-ring. If it is successful it will be called My Everything Lanyard ;-)
