OutofMyTree: I am very curious as to how you have the cordage tied 'inside' of the pulley. How does is it work? Better yet, does it work?
I posted this somewhere else but I am too lazy to look for the link. This is my usual blocking down set up except I use a different friction hitch now.
If I have any concern about the trunk splitting when the top comes out I use tie down straps rated to 1400kg. If they split I was dead anyway. :greenchainsaw:
Now I see what you meant SJ. I had a mental picture of that rig but without the krab captured by the f8 termination. I thought you meant to tie the f8 back on the rope itself. The weight of the krab makes a real difference when retrieving the rope. You could also use a friction hitch instead of the descender although if you rappel of course the hitch will need to be worked off at the bottom.
Nice clear pictures too. Easy to understand. Good stuff!
the F8 revolver works well for working a single line with a hitch
