Drilled/manufactured non-bolted protection
|
I was sitting in a meeting and my mind was wandering and I had a thought about protection and new route development. I wasnt sure where best to ask but I figured you guys were the ones with the drills so it's a good place to start. |

Never heard of drilled threads, but these are interesting: backcountrygear.com/1-2-in-… |

I've heard of people hand drilling threads in soft desert sandstone. Obviously, that would be a pain, and a mechanical bolt would be better from a climber's perspective. |

I would think, generally speaking, drilling threads and/or gear placements would bring more attention to an area than a single bolt (especially if the bolt is colored to match the rock) would, therefore a reason why it is not a common thing...Also does not seem like a placement that would last long or hold up well. I'm sure there is an example of this, but I can't think of any off the top of my head. |

I'm not an expert so this might be wrong, but here's what I learned in Andy Kirkpatrick's book: |

There are drilled threads as trad belays/rap points on the sea cliffs in the UK where I come from. |

I think rather more often it's for multi-pitch routes with inconvienient top access, or long/difficult approach. There's a reason that lots more routes at most 35 meters high with hiking access to their top get bolted than longer multi-pitch routes.The sheer physical labor of getting the equipment up into the middle of a muiti-pitch cliff (after first bringing it in from the trailhead) becomes daunting to well-intentioned developers who happen to lack "animal" hauling capacity (or enthusiastic partners with such capacity). Enthusiasm might get you thru your first project, but the memories deter you from a second, push you toward looking harder for accessible 30-meter routes. Especially if not certain how popular a new multi-pitch route will become long-term. The first obvious method of reducing the hauling burden is simply to leave the intermediate protection more run-out. And install two-bolt anchors with no chains or rings. . . . I think one of the advantages of vertically-offset anchor bolts (unlike "normal American" horizontal) is that it's easier to manage a progression from non-connected (so each climbing party must bring their own connecting sling) to connected-with-cord (so a climbing party only needs to sacrifice their own sling if the cord is getting worn out), and finally to chain (with ring?). The next level of haul-weight-saving is to drill only the _holes_ for intermediate protection, so then each climbing party must bring their own (removable) hardware to place temporarily into (or through) the holes (e.g. like NOTs / ClimbTech removables). One of the less-expensive models requires at least 1/2 inch hole (so in hard rock you're still likely going to be hauling a drill with batteries). . . . I recall the new West Utah Desert guidebook describes several routes around Ibex designed for removable protection. Then each party needs to decide how much time to waste "leapfrogging" their removable protection versus carrying more pieces. . . . (If the route becomes popular, a developer can later install permanent bolts into those holes -- likely after some re-drilling). Substantial problem for future climbing parties carrying removable protection for using drilled holes (which lack cord or stud) in interesing well-featured rock is for the Leader to find each hole.

I believe it was the Hubers that drilled a hole in a flake on an El Cap free route. |

i have drilled threads in Thailand at the thin part (back) of a tufa due to the cost of titanium bolts and rusting of other bolts. Threads were bomber, used static line. |

The problem is you need to tap the RB's with a punch or something similar (3/8 drill bit..) and a hammer to get them out once they've been loaded. A bit hard to do with out ruining the Tronsight. |

If one is tying this, you will find these far better than RB's. https://www.petzl.com/US/en/Sport/Anchors/COEUR-PULSE |

There are a few routes up in the far NORTH west parts of California that are made for those Climbtech RB's, the majority of them are right on the beach and came before ti bolts were a bigger thing. |

What is your experience with these? How do they climb? How difficult are the holes to locate on lead? How do the holes hold up? What type of rock? |

I have thought about taking a circular saw with a diamond blade and sawing a groove into the rock that you could then use a cam in, probably a ball nut. Never pursued it or even know if a battery powered circular saw could cut a groove in the rock. I just thought it would be nice to avoid leaving bolts all over the place. |

We have been experimenting with drilled protection pockets. Three ½ inch holes next to each other horizontally followed by removing the peaks between the holes makes a good slot for a .3 X4. Other small units also fit. We are putting them in on sections of routes that are easier than the crux sections with regular bolts through the crux sections. (Routes with 15-20 feet of 5.11 or 5.12 and 40 or 50 feet of 5.9 or 5.8.) They mean fewer bolts to maintain, camouflage and replace in the future. They mean less visual impact, especially when the easier section is the bottom of the route. The drilled protection pockets are invisible to non-climbers and the slots are less likely to draw objections than bolts. While it is true that the pockets can be used for climbing – so can a bolt – and they are not in the hard sections where “cheating” is an issue. Also, although a hard fall may crimp the cam stem, they are on sections where you might want some protection, but falls are unlikely. The cams are easier to work with than the removable bolts. The cams can handle imperfections in the pocket from the initial drilling or from wear over time. I don't think this is true of holes for rbs or the Pulse. There are places where land managers have banned “sport” climbing which they define as all bolted or bolt intensive routes. These routes are a way around those prohibitions. Whether or not climbers have the flexibility to accept such changes to standard practices or will just add bolts so that they don't have to carry a few cams in addition to their draws is another question. |

You're already going to that trouble of drilling holes, and buying the RB's ($70 each). So if you don't bolt them all you've done is put scars into the rock, and made a potential profit center for Climbtech (nothing against them, just why?). Or you could spend less money and just equip it with Ti glue in since you've already done the damage and spent the time drilling and now you've created something that has WAY more value to the climbing community. |

Being that it hasn’t been covered yet those ClimbTech removable bolts are rather fickle. If you place them too deep or they bottom out they are stuck. I find that drilling the hole with a considerable downward angle is the only way to keep the cable from kinking. I have always needed to use a hammer with a pointy object to remove them after I have weighted them. Perhaps I am not doing it right but they are quite different in usability than a standard climbing cam. |

You might try to contact some of the guys that were around then. But my personal experience with natural threads is that they're a pain in the ass. I eventually replaced them with Ti bolts. The nylon has to be replaced every year or so due to deterioration from the sun & wind, not to mention potential animal gnawing. Are you gonna do it? And BTW, no one is gonna want to thread each one as they climb, and then clean it on the way down: a total PITA.And they can be hard to clip, the draw moves around and creates situations were it might unclip itself. |
