      ok so load the guns….

      its awesome that some hard working folks have donated time and energy to replacing top anchors with stonkingly good ring bolts, but its pretty lame watching climbers toproping (over and over and over)thru the ring bolts.

      This will accelerate wear on the rings which are a challenging prospect to replace.

      Its really easy to use a couple of biners/slings whatever to set an equalised top anchor which virtually eliminates wear on the rings.

      SS maillons, twist shackles or similar fixed to the rings might be a solution but it costs$

      And while I’m here whats the story with using glav laplinks (chain joiners) as top anchors? Thats well dodgy….

      And good looking new lines bolted with bash in carrots?

      Fire away..

        Funny, this has definately been mentioned before…….not sure by who???.

        Definately hear you Ed and totally agree, but the question is who is going to dig deep into there own cash and buy the hardware (Ive spent enough already!). I can get stainless steel twisted shackles for around $8 each.

        So if you can raiss the money, I’ll happily put in an order.

          Hey Ed!

          Also spent heaps and still spending. It’s quite easy to use biners while the top roping is going on and then once finished, thread through the bolts and rap off – NOT be lowered off. Raping off is better for the bolts and the persons rope.

            ok george, but its really the responsibility of the FA is’nt it? i’m very happy to donate some ss trubolts and other bits and pieces which i have

            i do struggle with people being cheap over top anchors, if a runner bolt fails you may get hurt/kilkled but if a top anchor blows… el mort

              Hi Ed,

              Problem is too many climbers don’t know you shouldn’t run a loaded rope through a pair of rings or why. Writing stuff for our magazine today and will put a tech tip on it.

              As for the bash-ins, some people want their names on a lot off climbs but aren’t prepared to put the money into even GIMBS. Its fairly easy to work out what’s going on.

                yep, good idea Toc

                does seem to be an emphasis on quantity over quality

                keep in touch over blackwall reach, not sure of my parenting commitments tommorow mate

                it does seem like some developers here have a very bizzrae conceptt of developing, ie use power drills to manufacture routes, drill holes for bolts but then fill the holes with the most crap bolts , it seems fair to me that if your going to spend a pile of $ on drills, drill bits etc you may as well put in top quality gear

                and as a slightly twisted ethical aside…

                is it alright to enhance holds on a manufactured route?

                  Hi Ed,

                  Some people manufacture routes in the quarries and seem to get away with it. You’d get skun doing it outside of the quarries.

                  It’s all academic for me, I don’t climb at the level where I’m going to run out of climbs.

                  Cheers,

                      without the old guard and their bashins we’d be living in a pretty sparse environment. anyone following on can replace with shiney SS GMHBs, or retrobolt with Ps. all-in-all the system seems to work pretty well.

                        Ed – where have you seen this? I have never seen an excessively worn SS ring bolt, anywhere. But I have seen many mild steel (i.e. soft metal) hardware store shackles. I’m not saying your concern is not legit just that I have never seen it. Anyone else?

                          Maybe in a perfect world the FA would equip every route with twisted Shackles/or equivilent. But the reality is, they don’t! 1. The quarries are probably the only place that sees enough traffic to even slightly wear the rings out and from most i have looked at,they seem to be totally fine 2. I think that lowering off the route and having double figures people toproping all day long are 2 totally different kettles of fish!. Lowering off is fine, thats why they are there(perth really doesn’t see the traffic to wear through rings quickly). The whole toproping (which seems to be happening in mass proportion…well for perth anyway on routes like penthouse and playboy) is of most concern.

                          Hey, if you are out there and people are keeping on doing this, firstly politely explain an alternative(i.e there own bloody biners) and secondly if that falls on deaf ears, ask them if they would mind donating money to the replacement cost.

                          Thanks for the offer of Bolts, but i have plenty, twist shackles would be the go:)

                          peace

                            lowering off is fine, but repeated top roping will over time lead to wear issues besides which its bad practise

                            mind you i’d rather lower off a worn ring bolt then those galv laplinks on carrot bolts!

                            george i have a few ss ring hangers..

                              I definately think we are both on the same wave length. I have around 15 Fixe double ring hangers and Im sure we there will be need for more.

                              having not climbed lots in the quarries which routes could do with new or better loweroffs.

                              I would much rather use glued in machine bolts to fix the ring hangers with and not use trubolts.

                                  just cuious why you prefer GIMB over trubolts?

                                    mainly because they are harder to tamper with, don’t loosen over time and with the advent of RE500 are stronger, there is also no outward friction pressure, as with expansions.

                                    But hey, you cant beat the ease of slotting in a trubolt. But i don’t think that ease of placement should be the reason behind anchor choice, strength should!. :)g

                                      Richard has a point. We can all climb on manky bash-ins and if we like the route, put decent gear in. I did see a Mike Law article years ago, pointing out that a good carrot is probably going to hold better than a poor wire. A well glued glued bolt holds best. A badly glued bolt will hold jack-sh**. All pressure type bolting systems put strain on the rock which has already been stressed by being drilled. A geo physicist explained to me the formation of a conic fracture zone around drill sites, (which is why you don’t drill holes close together). Wet glues like HY 500 can soak into the fracture zones a little and offer some repair mechanism but pressure bolts, (and bash-ins), exacerbate the fracture zone. It’s not a problem that often, but I believe it was Mountain Quarry where a climber fell a few years ago, and the rock around the bolt failed and he ended up on the ground, (shaken, not stirred), with the bolt still in the piece of rock along side of him. (I’ve clipped a lot of pressure bolts and bash-ins), (and glues must be well done or they fail), but that’s the theory behind it. For those just starting to come outside who are certain bolts are good and natural gear is dodgy, all bolts are climb at your own risk propositions. What scares me is climbers coming outdoors with ability honed in the gyms, no technical gear skills, going onto hard mixed routes and repeatly falling onto carrots or actually any bolts, which they got to without putting any natural gear in. Just guessing but it seems to me that it is the lack of technical gear skills, (and laziness), which would stop climbers from putting slings or cordellettes into the lower offs for top roping or abseiling off the rings and pulling the rope through unloaded at the end of a session. There are other factors to think about here, beyond just wear as well. Lowering off through the rings involves a load greater than that of the climber, (it also includes a component from the belayer), and a direction vector that is not necessarily ideal. Abseiling off has the same direction vector issues, but less load, (no belayer).

                                        yep i agree with richard in so far as historically many routes were equipped with carrots, but that is and should remain history, and caps off to those pioneers

                                        but that dosnt mean its right to use the same outmoded technology today

                                        expansion style bolts are used around the world , i have decked from a route where an expansion bolt pulled the entire piece of rock off and it hurt

                                        if expansion bolts are failing in solid granite someone should call the folks replacing the bolts on el capitan right away… in my experience bolts seldom fail as such but rock does.. and thats most often cause people place bolts in bad, fractured, exfoliating or otherwise poor places

                                        Brett pulled a carrot at the quarry recently, sounds like it came out along with the rock…

                                          Im not saying there is anything wrong with expansions, especially not in hard rock…they are bomber.

                                          I gave a personal preference for fixing loweroff ring hangers in areas such as quarries were they may get tampered with ..nothing else.

                                          From my experience in replacing bolts, there is more risk of the bolt breaking/shearing off flush with the wall(due to corrosion from incorrect placement) than actually pulling out.

                                          As for bashins, I think they have a place in a wilderness/ or low impact area. But in a quarry i think they are a cheap and selfish pile of $%#@.

                                            Hey Ed, yeah, the carrot (I still have it!) & a chunk of rock came out together, on that manky rock past the gulley left of the Skywalker wall – there’s an old post on this site where I detailed it.

                                            I had just clipped it & was resting on the rope – fell back to the 1st bolt, which held – so a few scrapes only!

                                            Certainly made me think a pro. a lot more, & I always use extra gear & slings the few times I lead outdoors!

                                            Also, agree with you about those chains – some are pretty scary!!

                                            cheers

                                              There are many pics on the web of anchors that have been worn through from people TRing directly thru them, here’s one (unfortunately it’s oriented upside down but you get the idea):

                                              When I see anyone TRing off the top anchors I give them absolute hell. Usually they are just being lazy. Use your own biners!!

                                                As far as Im concerned, glue in Fixe P’s that are inset, and glued with HIT RE 500 are minimal on the eye and sooooo bomber it will save some other poor bastard having to go up and re-bolt the lines for a very long time. Not to mention of course the comfort of mind when you clip them! 🙂

                                                    Some info from an Oz site on top anchors.

                                                    http://www.safercliffs.org/code/rap_anchors.html

                                                    Havent seen too much evidence of wear in WA, but then I havent climbed here extensively. It can creep up pretty quickly on popular climbs, and its a pain to replace rings.

                                                    Wear on anchors is a problem in Nowra and the Blueys, SS shackles are used on some popular routes.

                                                    Surely Bash ins are no longer used ? only in the days when climbs were bolted on lead using handrills..we have moved on now, notice how ropes are no longer made from hemp ?
