Rope grooves & rappeling

[oldno7]

What brand of rope?

I guess you have to keep your replies short when responding from a pew?

How did you know

I'm home now. I was using a 8.3 ICG when I was testing this idea. It was pretty stiff at the time. I will go try your stein concept next time I am out.

Yours is not a stone hitch, others have had similar release problems when tied improper.

When tied as I showed in "how do you stein" I have had it release everytime, up to 200'; really pretty fun to watch come down.

Just make sure your pull path is clear, so the dowel cannot get lodged in a crack or ??

Looks like a downward, overhand Stone to me.

That is what it is. It is what you taught us eons ago in Mystery.

We set up this releasable(stone) yesterday in Mystery. Used the old ICG 9mm line.
It definitely required more dressing on the dowel.(it was dressed tighter before rapping than in the pic.) The release was somewhat hilarious and easy. (Tyler gave it a yank and it came down and pegged him in the thigh) The rap line hung a little but a gentle tug and it came down with ease.

So I think rope diameter has an effect on this system but proper set up is more important.

We also backed up this system with meat.

This dowel is 1" and has an resin coating.

Nice friction-hitch backup - well done sir!

Give Old No. 7 an award. When you tie it with the upward 8 stone it works flawlessly. The knot just falls apart. Thanks for the tip.

Mark, looks very good, I really like the safety clip.

What kind of pipe have you found works best and what size?
