Slap down all the way from Germany!

Thanks the Jim! :-)

Well many of the Europeans that end up bolting in Australia have no experience of sandstone. In 2009 we had two groups from two different countries placing expansions in the blue mountains. Both groups had bolted all around the world - with expansions.

Iīve seen Australians come to the Oktoberfest and get so pissed they throw up, I guess this proves all Australians canīt hold their beer!

There are sandstone crags all over Europe but since sandstone doesnīt lend itself to really hard routes it doesnīt get in the news much and to be honest most climbers prefer other rock types anyway as a lot of sandstone needs techniques a bit different to limestone.
A good number of them are either in crap places or crap in themselves anyway so donīt attrack outside visitors and it doesnīt give particularly good sport routes most of the time anyway if you asked me. Iīve climbed on maybe 20 because I was there but wouldnīt make a trip specially to go sandstone bolt climbing.

The Euros went through this discussion way back and had already worked out a reliable way of bolting even the softest sandstone in the early 1900īs and started to go over to stainless glue-ins in the late 1960īs. There are maybe 50,000 bolts in the Elbe Sandstone and they donīt come loose or fall out.
The Americans have struggled through all the mechanical bolt systems more recently (apart from carrots!) as they have enormous numbers of sandstone cliffs as well and for the soft rock itīs either 5/8" x 4" or glue-ins these days. For Australians to ignore the experience gained on other continents strikes me as burying ones head in the sand but we then donīt have ostriches here either!

As an engineer who has never placed an expansion bolt in rock, please tell me that it is standard practice to use a torque wrench when tightening dynabolts?

As an engineer, you may not like the answer to this question...

Pretty much all the bolts in the swanage and portland limestone on the south coast of the UK are glue in stainless staples/ring bolts. Even though it's limestone, and it's coastal, The top part of it is often crumbly. The expansion bolts that were originally used didn't stand the test of time and got replaced with staples or ring bolts.

You also can't lower directly of carrots, so it requires access to the top of the cliff.

I got a reply from Malcolm whilst I was overseas...

----------------

I have tested my carrots and broken hangers in direct pull out. But then I have also have had two glue in rings fail on me too! I gues its natural variation in placement and or place-er. Not good though. The two other bolts you refered to, first bolt on After Midnight and forth bolt on Path of Yin while superficialy look like carrots are actually 1/2 x 3 1/2 inch Raul expansion bolts that I bought back from the States and are probably some of the strongest bolts out there. While not stainless they certainly are not mild steel, in fact grade 8 carbon steel. I used quite a few of these around about the place, mostly on steepground.

Even rusted to shit they probably are twice as strong as the quick draw you will clip it, with, which isn't saying much as most bolts are stronger than caribiners no matter what their condition. However I think some bolts may need some attention and I have thought about some of mine. But over reaction is not the answer, as I have mentioned I have had two glue ins rings pull out on me and have heard of many others failing but should that mean that all glue ins are shit and should be replaced, I don't think so. Climbing is potentially dangerous and all types of bolts potentially could fail. Best not to think about it too hard if you want to go climbing. Maybe trad is safer?

Anyway I will look at some of my older bolts with a more critical eye from now on.

Good to get a reply which is carefully worded at least. Raising the bit about glue ins though is a bit of a diversionary tactic given that the question is not about glue-ins.

Unagressively worded yes but at the same time totally random with no outcome.

Well said! I certainly trust your judgement...

And the comments about glue-ins is well deserved here, given that they are part of what is being discussed, even if only to remind people that glue-ins are not always bomber, and that they can and do fail.... I have certainly seen many dodgy and failing rings etc... Possibly more then bad carrots...

And yeah Trad probably is safer, or at least you die by your own hand, rather then someone else's...
