Trying out my mini-wrench hook combo

[moss]

So here is a mini-bone build. It grips reasonably well on the reep schnur, but once weighted it, it does not want to release its bite on the line. Back to the drawing board for me......View attachment 83753

Very cool! Looking forward to what’s next.

@surveyor Have you been tinkering any with that scissor design?

not much, I need to revisit that also.

This has potential on a hook line using reep schnur 3/8"

Can I quadruple heart this?

 

[moss]

Wow, that looks amazing Gordon!

There’s no way a hitch/wrench can compete with how compact that is. Take my money please.

I’ll stop gushing in a minute ;-) It’s compact enough that adding a swivel in will make it even more versatile for long lanyard use and won’t take anything way from it.

I think I will need to send it out as a demo to you three, you may hate it. It can be a bit stiff on line when fully weighted on a single line. It releases with some force using the top arm when fully weighted and will tend like the regular Bone, just takes more effort. it may actually be best to advance it when on a hook line by pushing it along directly. On the plus side it does not slide down line when unweighted and it can potentially replace the pulley, hitch, tether and wrench. It is all stainless steel and aluminum alloy and nylon ends.

Not going to hate it and promise not to dissect it ;-) Excellent that it doesn’t slide down when unweighted. I would definitely test it on a 9mm static line.

Add me to the list if I'm not on it, looks awesome!

Will gladly provide lots of feedback and doubt I'd hate it!

So Moss and all, I tried an elongated bollard also on the 3/8" Bone and it does help with the gripiness, in fact it will grip on a (new) doubled 8mm line, but not quite on the single line.

@surveyor Did this by chance become more than a prototype? It looks very nice!

 

[surveyor]

It is still one of a kind, I'll have to look round in the morning and see if it still exists. I sometimes reuse parts for the next idea I might have. If not, I am quite sure I could make another...

I'm such a jerk I still have parts of that. Want to make two more mini wrenches from it. It's worth pursuing an all mechanical for 9mm range lines if only to make Captain Hook climbing as ultimate as it can be.

No worries. Moss has made an improvement to the hybrid usefulness, with the mini wrench idea. 9mm use seems a better idea than 8mm, and I have some 9mm on hand.

I've got the DMM hook on about 50' of 10mm Reep Schnur that I'm planning to set up as a double-ended lanyard thing with a snap or carabiner on the other end. I've found that I rarely used my previous lanyard on the side Ds of my harness, but instead often used it as a secondary climbing system, either cinching it around or looping it over something and climbing it with my foot ascender. I haven't tried this technique with this rope, but it seems a small device capable of smooth operation in SRT mode would be perfect for this kind of use.

It looks like you are using an Ultra O on the line you are carabiner choking. What is your reason for using that rather than a PerfectO?

Ultra O is my preferred size for any make/manufacturer auto-locking carabiner. Best ergonomics for my hands, best overall functionality for all the ways I use a carabiner in tree climbing.

I had tried using the Perfect O for general climbing use and didn't like the small size. For my Captain Hook line mini-wrench system it's perfect. It has one role only, anchoring my Hook system to my harness bridge ring or swivel. The shorter length matters, helps keep my min-wrench system length as short as is possible.

"Miniaturization" of gear is an interesting design direction but there's a point where being too small can start causing disadvantages. For example I have little use for the DMM XSRE (a couple exceptions), I prefer the Kong mini-D for a well-made non-life support accessory carabiner, the form factor is perfect for my uses.

I climb all winter, hands and fingers can get clumsy in cold weather, fidgeting with smaller gear can be a problem.
