re bolting techniques
|
if you are involved in replacing old bolts on multipitch routes i'd be interested in reading your chosen course of action. i've recently started going ground up, replacing as i go, with the second climber removing the old ones. i cobbled together a bag from old carpet scraps and hang it from a fifi hook on the new bolt and retrieve it with a short tag line when i reach the next bolt to be replaced. the bag holds the bosch, hammer, wrench, blow tube, bolts etc. and allows me to climb mostly unencumbered. obviously the tag line needs to be longer than the distance between bolts/gear but things seem to work okay. surely others have devised methods that might be more efficient than mine and can help short circuit the learning curve. |

how are you replacing the old bolt with it still in the wall? It sounds as though you are adding new bolts and then having the second remove the old one... Are the old holes no longer usable? Seems like this technique could produce a lot more damage over time, say after four replacements. Obviously not every hole can be re-used, but it's just a thought. |

i've never been able to extract an old bolt and reuse the hole. i've read where others have been successful doing that but i have not. i share your sensitivity toward repeated replacements long term. i use only stainless half inch bolts and what i consider the best hangers on the market. there is no chance you have spent more time considering these impacts than i have as it pertains to these routes. the bolts i'm replacing are 25 years old. most are stainless smc hangers on rusty 3/8 bolts. at the time they were first installed they were as good as it got around here. now they need replacing. i was hoping for information gathered from the experiences of others who are also replacing bolts on multipitch lines. there are circumstances and challenges that complicate the process compared to replacements on single pitch climbs that are easily done top down. you are entitled to weigh your judgement, as we all are, but what interests me would be your insights. |

Just to be clear...what you are doing is retro bolting, not bolt replacement. Not saying it's a sin or anything. |

I have not done much bolting or removal personally, and I also do not disagree with adding new bolts as per your style. It seems to me that if you are replacing 3/8 with 1/2 inch bolts it would not matter the condition of the previous hole because you are just increasing its diameter by an eighth of an inch. This would be easier on your batteries, drill, and require less replacement bits. I would try and investigate methods of removing the previous bolts such as the tuning fork method rockandice.com/articles/how…;>> as you do have a hammer drill it doesn't really matter if the old bolt shears off... Just my opinion but any way of limiting old bolt stubs would be great, especially if this new hardware will last for much longer. Nonetheless it is great that you are investing time and money towards making climbing safer for everybody. |

Are the half inch bolts you are putting in sleeve bolts? If so kudos for replacing the bolts with something that will be replaceable down the road. |

This ought to be an interesting thread.this doesn't sound at all like retrobolting (?). you might contact kevin stricker through this site. he has experience doing extensive bolt replacement on big routes. i would think that doing it top down would still be a lot easier, even if it is on a really steep wall that would require shenanigans that are similar to down aiding, etc. if you can find a way to re-use the old hole that would be helpful, but sometimes it doesn't work that way. anyway, glad to hear that you are replacing some of the old stuff. |

If you are replacing with stainless steel, you won't have to replace again for perhaps 50 years. If you replace with stainless steel glue ins, you won't have to replace again for perhaps 500 years. |

Quite sure actually. Changing the location of a bolt can dramatically change the character of a climb and make it very different from the route that the FA climbed. Again, not saying there is anything wrong with that. Sometimes that's what has to be done. I personally would be in favor of yanking and patching the old hole if it's unusable. This is hard work and rather inconvenient. I realize that climbing is supposed to be convenient now and most don't want to be bothered with that whole "leaving as little trace as possible" let alone "leave NO trace" thing. I feel one should at least make an effort to do this before turning your local crag into swiss cheese, but I'm not a local so...drill baby drill. |

For 1/4" bolts I am something like 10/10 in being able to pull and re-use the hole. I forget how many 5/16, something like 3/3. Do your homework and many will come out clean, or else you are likely just fouling things up for the rest of us. |

That rock is bomber granite, so any new holes need only be slightly re-located. And by the way, we ain't talking about sport routes here... Anyway, I believe he was looking for ideas about efficiency.This. Leeroy wrote: Thanks for that Mr. Montoya I am absolutely certain that in my local area this would be considered retro-bolting.

Moving the bolt a couple of inches is not retrobolting and is not going change the character of the climb. If you honestly beleive that these routes are being turned into "swiss cheese" I suggest you come climb a few of them. They are not sport routes and the possibility exists that you might soil yourself just trying to find the next bolt! |

If the old bolts are so bad that you don't want to lead out on them, I'm not sure of a better method than what you're doing. I'd carry a couple of bolts/hangers/draws preloaded on my harness, along with the blow tube and the wrench. I'd probably climb with the hammer too, just because I try to use the same kind of setup as much as I can and my shoulders don't like the hauling. Thats just personal preference though. |

However, assuming you're using the ASCA 5 pieces (from LGO), be sure to watch those nuts/cones on the end, they have a tendency to fall off. |

Retrobolting is adding, not replacing, bolts on a climb that changes its character. Replacing bolts in a new hole close by isn't retrobolting, though it is better if you can reuse the hole. Not always easy though. You'll rarely notice it if the hole is camo'ed well in any case. |
