Making a rope anchor without twisting
|

|
The picture doesn't really show much but the slack between the left piece and master point also twists a bit |

Am I tying them wrong and introducing an extra twist?My guess is that you are tying the cloves in the same direction, just tie each clove in the opposite direction of the one you previously tied and it will remove any twist that the first clove put in the rope. |

I think you're right on the nose. Thanks!!! |

i've seen the video that teaches that way and i have found that it takes much longer than the way i learned and uses more gear. imo this is the best way to anchor with the rope using 3 pieces: rope anchor |

I think you need an 80 meter rope. So you have some left to climb with. |

Eli do you have another link for that video?^ the one above doesn't wanna work for me. |

i forgot to mention, instead of cloving the pieces back to a locker on my belay loop like the video, i clove the line going to my tie-in to the masterpoint (or the shelf) after finishing the anchor. makes it easier to give myself slack if i need to move around on a big ledge ie to see my second |

Yea I couldn't get on. Booted me |

Get rid of the cloves, run the rope through all the biners and just tie a single knot on the master point. |

[trigger warning: cat lovers leave now.]
There are many ways to skin a cat. Here's yet another variation on the theme in your quest for efficiency that uses fewer 'biners but more exotic knots: youtube.com/watch?v=OJ8I6z-… One of many methods - clove your first piece with a couple feet of extra slack between that and your tie-in. Tie a 'bunny ears' two-loop figure of 8 and clip the next two pieces, adjusting the size of the loops for the direction of pull. Tie a BigHonkin'Knot on a bight using both your tie-in and the rope running out of the bunny ears knot to make a master point in the direction of expected pull. Keep at least one carabiner in the master point loop since your tie-in now loads the back side of that knot. |

My system The loop in the slack for redirection point is optional---I rarely tie that. The system is similar to the one on the climbinglife site, but is more efficient in that you don't have to estimate the lengths of any pieces that are tied later. I've never had a a rope-kinking problem from the clove hitches. |

Dumb question, but does anchoring with the rope only make sense when swapping leads? If there some chance the leader will be leading the next pitch, this anchor doesn't seem very appropriate. Correct? Thanks ... and yes, I know, yer gonna die ... |

If you did you would have to both untie and switch the ends of the rope you are tied into or build a 2nd anchor with the 2nds end of the rope and than take down the first anchor etc. |

By clipping free strand to "power point" with a biner, would that cause cross loading to biner being clipped into? |

A cordelette is faster in this case, but only by a little if both party members are competent and the second carries four carabiners they can use to build their own rope anchor under the leader's. In a guiding situation or with a person who isn't knowlegeable and efficient, the cordelette is definitely the way to go.

I did mean to suggest/confirm that building a rope anchor per the systems discussed above would only make sense when swapping leads. I agree it does not make sense when guiding or leading in blocks with a less efficient second, as a cordelette would be faster in those scenarios. Your comment, "You mean not swapping leads," initially confused me because I thought it was meant to respond to the first sentence of my original question, when in fact, I think you meant it as an alternate way to restate the scenario described in my second sentence "If there [is] some chance the leader [also] will be leading the next pitch, ..." |

BigFeet, in your top picture what is the purpose of clipping the left strand into the top shelf of the anchor? |
