wrench and wrench

[treebing]

had a play with this set up and loved it. Got to work on my other wrench a little as it needs to be straightened out a bit. did as best I could but it makes working this thing sweeeet.

Kevin, I don't see a wrench and wrench pictured, just a regular RW setup. Am I missing something?

 

[Tr33Climb3r]

Kev, Hard to tell with that picture but is what you are highlighting a solid tether? Which implies the name of the thread. Just hard to tell with the picture.

I had a thought or more like a what if the tether was solid but never acted on it.

 

[tomthetreeman]

I think the tether is actually a wrench!

Gordon, the tether in the picture is also a wrench.

Cool,Kevin. A hard tether on the wrench does seen to enhance and add stability to the RW.

great, more hard stuff to smack me in the face!

But seriously, that is interesting.

I can see that it would quickly pivot the ropewrench upward when ascending.

did you find you needed the ropewrench to release sooner than when your prussic pushed it upward?

this wrench likely keeps it all aligned better too, huh?

let us know how it performed.

thanks

 

[Blinky]

Interesting.

Doing this makes it even more a 'mechanical hitch' which I understand qualifies it for use in a TCC!

I could see using a small turnbuckle in order to dial-in the exact length. Jam nuts, maybe even wing nuts would be perfect. The catch..finding a reverse threaded jam nut for the bottom. But, if that isn't possible maybe even a piece of rubber tubing to jam the threads.

Length doesnt matter so much so long as it leaves room for the hitch. I am custom making a bunch of solid tethers. It doesnt seem to smack me around more than usual and my hitch tends so much nicer. There is also no risk of ig tangleing in a rope tether. Chris cowell originally proposed the solid tether idea and its taken 6 months to actually try it. So far i like.

I would be love to test one out after you get some made. It looks like a great idea especially while ascending. Let me know what I need to do to get one when you finish making them.

cool, i like my petzl dogbone tether, nice and stiff.

 

[chris_girard]

Cary, what length petzl dogbone are you using? Did you switch the rock climber biners out for arbo posi-lock ones?

 

[GibsonTreeCare]

only the webbed tether, I have DMM ultra "O"'s in there like I always used.

 

[goodaking]

Very cool!!

 

[oceans]

I think girthing the factory tether into the top hole of the HC pulley offers a similar effect. I first ran the Wrench with a biner to make that connection and quickly stopped since it seemed much slicker without it flopping there. I still like the idea! Another step of positive SRT evolution!

 

[frank]

interesting stuff. i'm looking forward to having you in minnesota this summer for a workshop...

 

[mattbever]

Frank what is this workshop u speak of?

 

[mattbever]

Kevin, What about a hard plastic 'solid' tether. May afford a fat lip rather than a trip to the dentist...just thinking out loud. Less weight, no extra metal clanking about. I don't know anything about plastics but....rated???

 

[trevmcrev]

My first thought was "i can't believe you actually tried that" my second thought was " of course kevin would try that"

I really like the efficiency of a rigid link used here instead of the cord tether.

Just for kicks here are some random thoughts on a rigid link construction that demand to be beta tested. Any taker?

1.Oak dowel rod with a pair of closed eye hooks lagged into holes drilled in each end. Easy to cut to length; light weight; adjustable. Kinda like a wooden turnbuckle.

2.You could go with metal with a pair of eye hooks with machine screw threads attached with a thread rod coupling nut. Or if an exact fixed length is known I can bend a metal rod with eyes on each end. Real clean. I better email Luke with so if he likes this he can get the drop on tobe.

3.Plastic tube with slightly longer loop of bungee cord slipped inside that is tied with a grapevine so you have an "eye" coming out of both ends.

4.Plastic tube with each end heated and smashed flat; then drilled holes in each end.

I can go on and on and on but until these prototypes are made/tested/perfected I will have to stop.

See you at the top,
Dan
