Rope Anchor (video demonstration)
|
I recently switched from using a cordelette to the rope as my primary anchor rigging method. Initially, I was intimidated by the concept, and by the examples I was able to find online. At first glance, they looked complex and appeared to violate the concept of KISS. |

that works. thanks for the time to make/post the vid. |

Thanks for taking the time to make that |

KISS? I have never heard of this one. Could some one explain |

Thanks for the link, another good one to know, Roger. I believe there is a significant disadvantage, though. I tried rigging this just now, and it doesn't really work when the pieces are in a horizontal orientation, does it? The v-angle greatly exceeds 90 degrees, unless you position the master point way down at knee-waist level, which is less than ideal. I suppose you could position yourself lower to begin with, but this raises a host of new issues. Do you use this method if your pieces are set horizontally? I wonder if I'm missing something. |

Hi Jason. Thanks for the video. Personally, I usually go with something very similar to the link posted below (climbinglife.com). IMHO, it is an easier set-up. However, that is just me. Your method looks fine and if you are comfortable with it, that's great! |

I fiddled with the other method some more, and I was able to tie in tight while keeping the master point at chest level. So scratch what I wrote above, I can see how it would work with the same horizontal orientation. I feel like both methods are about the same in terms of speed and complexity, but the method I posted certainly uses an extra carabiner. |

Thanks for making the video and posting. |

There'a a lot of discussion in this post from rc dot com about building anchors with the rope. rockclimbing.com/cgi-bin/fo…;post=2590836;page=1;sb=post_latest_reply;so=ASC;mh=25; You probably saw that thread when doing your research. What you posted seems to be a variation on the method rgold posted some years ago. His method is pretty simple and quick to implement. Can you tell us what you think are the advantages to your variation?Methinks you didn't read my entire post :) No advantages to my variation, just another way of doing it. |

With the belay off your hip regardless of guide mode or re-direct escaping the belay will still be much harder with this set up. isolating the belay master point will solve this (only to a certain extent obviously if using the rope in the anchor). Remember to not get sucked into one method, but instead have a full bag of tricks up your sleeve. |

Thanks a lot, KenIndeed, if not swinging leads it is hard to beat the cordelette in terms of speed and efficiency. However, it is not THAT difficult to swap positions using a rope anchor like this. It only takes a minute or so for the follower to clip in to each piece, effectively building their own rope anchor on top of the original one. The pieces are already there. Unless you're truly hauling ass, it's really a non-factor IMO. Most would probably disagree, though. Definitely more potential for clusterfuckage. |

Very good,, an advantage to a cordalette? I doubt it Use the rope, you paid $$ or it |

If you belay off the harness and need to escape the belay you have to transfer the fallen climber to the anchor before you are free. |

Hmm, no issues with what you wound up for the autoblock setup, but for what you've shown for the redirect and belay off of the harness, I see an issue (someone correct me if I've missed something). The issue is that whenever you re-direct off the anchor, you put double the load of the fall on the anchor. In this case, you've isolated one of your anchor points, so only two of the three points will experience double the force of the followers fall. Yeah, not likely to be a problem for the follower on top-rope. But... |

But...Redirecting does increase the force on those two pieces, but as far as I am aware it is common practice, and perhaps even more common to redirect through a single piece? I don't redirect and never have, but I would speculate that those who choose to are not redirecting through the power point (cordelette or rope). |

I think that gets at the fundamental problem with building the anchor out of rope: It works great with a party of two "swinging" leads -- so it's the partner of the one building the anchor who leads the next pitch. But what to do if the same person is leading several pitches in a row? My guess is that rope anchors got abandoned by guide-persons, because the guide was going to lead all the pitches, and didn't have a simple way to handle that with minimal client cooperation. Therefore they adopted of the cordelette. Then their clients assumed that the cordelette must be the "right" way because it's what the guide used. And nowadays with leading "in blocks" popular, this problem is live for lots of parties of more equal ability, where no one person is in a quasi "guide" role. So I'd be glad to hear more about how Method A versus B versus whatever addresses the situation of the same climber leading the next pitch - (perhaps with more-than-minimal cooperation by the non-leading partner). Thanks a lot, KenKen- when not swapping leads i almost always use a cordelette. exceptions would be if there are bomber bolted belays in which case i'd probably use a long sling (48"). to be honest, my cordelette just about always gets racked because where I climb there are a good amount of belay trees and it's my preference to back up the existing tat with my own cord. the decision to use the rope on a gear anchor or a long sling at bolts is basically because that's faster for me than unraveling the cordelette. I guess it goes back to what someone said earlier, we should be ready for anything and have as many options ready to go as possible. |
