double redi

Excellent!!

I was speaking to one of my colleagues about retrievable redirects and he mentioned that the way to do it was similar to this, though I think he mentioned some kind of friction hitch in the system - but i couldn't really visualise it.

cheers for the post.

In the set up above, the pulleys/krab might get stuck on the termination knot on the rope. If you had a big splice on the end of the line and used that to set it, the krab would slide off easier.

 

i dont think it will work with a spliced eye as the fishermans bites down on the bight. the fishermans will just pull undone if the biner catchs on it or if it catches ina crotch. but cheers rupe, its keeping me thinking...............is that the issue you meant by the way?

Yeah thats what I'm getting at, but yes I see what you mean. It depends on how much the fishermans is actually doing and whether the later bights are doing the work.

 

I just thought that when it all comes undone, the tail of the fishermans, or the knot itself might catch the Karabiner. So your tail end of rope is still round your re de point and your climbing line is still through the pulley(s). I doubt you would get enough pull to untie the fishermans especially if it was biting down hard on the first bite.

 

If it got stuck in a fork then you probably could undo it.

 

I will have to give it a try. I've got some blaze with a big 3inch splice in it.

 

What I do like about this set up is the lack of gear needed. You could effectively not have a re de with you and just set this sytem up with a spare karabiner, that kine of on the fly trick is better than carrying tons of geart for every unlikely occassion.

 

But yes I do still carry tons of gear!!

Thats excellent Drew.

 

I've used similar simple tricks, but I think yours is the most useable.

 

It will fit in with my 'minimalist versatility' climbing concept very well.

 

Thanks for the great pics.
