So you've identified your route and are all geared up. On to the drilling! AMI instructor and Chair of the Cumbria Bolt Fund Dan Robinson shows us how to test for solid rock and the best practices when drilling.
These are not designed to be standalone education videos and anyone intending to bolt for climbing should seek individual training from experienced or qualified persons before attempting anything you see in these clips.
Thanks to the Cumbria Bolt Fund, AMI and Land and Sky Media for contributing to this BMC TV film series.

Not convinced with the water cleaning

@srichavva3190 Год назад

also youd have to take a lot of water if you're gonna clean each hole right?

@BoltahDownunder 3 года назад

these glues that are rated for damp/wet holes are referring to a hole that's been washed clean, like with a hose. just wetting a hole before it's been cleaned of most dust will make a slurry that's harder to remove than dry dust, and reduce the bond strength. Often spec sheets will state, assume 1/2 strength for wet hole placement, or similar, but this is even worse than that as it's not just wet but muddy. Will it still be a solid enough bolt to climb on? Probably. Is it best practice? no. Is it a totally unnecessary step? yep. Am I going to lug a bunch of water up a line with me? god no.

As someone who climbed from the early 80s, this BMC sponsored bolting guide is mind-blowing. Back then, if you couldn't climb the route using "traditional" pro and natural features, you'd choose one you could. Bolts on natural crags on climbable routes get chopped - as was done in 2012 on the infamous "Compressor Route" in Cerro Torre bolt-laddered in 1970 by Cesare Maestri.

@nickhanshew9171 3 года назад

The Compressor Route was a bolt ladder. Properly bolted sport routes are not ladders. Some climbs are too thin/blank to safely protect with gear. This allows us to climb at our limit. Not that you don’t already know this. Just thought I would leave this for other folks to consider. Climbing is a selfish sport haha

@garthlyon 3 года назад

@@nickhanshew9171 Sure - "on climbable routes" means: if they have already been climbed 'free' of bolts. This is the beauty of dual-grading: if a route is considered too serious by a party, then there's plenty of great alternative routes that can be more securely protected without the need for drilling native rock for additional security. This is in complete alignment with the BMC whose own 'Ethics and Climbing' page states: "The BMC is firmly opposed to retrospective bolting (i.e. changing the character of a route by placing fixed equipment where none was previously used)." www.thebmc.co.uk/ethics-and-climbing

@fh8698 4 года назад

Great video but there are several statements that are simply incorrect in the first when discussing countersinking; it's not required for strength as EN9595 specifically includes a torque test with out counter sinking. The merits of countersinking apply to other issues. Cleaning holes out with water is unnecessary and just makes it worse when dressing the adhesive around the anchor. The twist leg shaft is not a right angle but actually inclined so drilling slightly upwards ensures the eye sits flush.

I can hear the mountains screaming in pain as you drill into them

@michaelogorman7195 4 года назад

Yep done a fair bit of bolting routes never used water but might be a new type of glue

@richardeden1453 4 года назад

no, not with epoxy it isn't

@benthespread 4 года назад

As a keen hiker and not a climber I've always viewed this practice as an act of vandalism

@alexm3892 4 года назад

You enjoy those footpath scars though

@nehnehnehbatman 3 года назад

@@alexm3892 he probably never even considered that as vandalism 😂

@nicholascrosby12 3 года назад

Oh ya dude! As a kid I would go TP peoples houses and egg cars. Then after a night of that we would go out into the forest and blot climbing routes..

@viajandoyaprendiendoconRicardo 7 месяцев назад

As a hiker I agree. Picture ourselves hiking the CDT on battery operated board on wheels and a chainsaw in case we bushwack or for bbq firewood.

@andrewneidhart3899 2 года назад

so people just drill their way up a new rockface? this totally takes so much away from the glamour of rock climbing. "yeah lets just literally drill into rock and climb a human creation," no disrespect but i think ive found this sport isnt for me. If you cant do it with power tools then... is it really conquering a mountain?

@Christian-kl8dl 2 года назад

You can always free solo if you like too....

@chilIychilI Год назад

Need to check out the hollow bits/rottery drills that suck out all of the dust as you drill the hole. Their still relatively newer so mixed reviews are par for the course. I'm an electrician so I just wanted to see if we used similar techniques and tools and we certainly do. But i'm a big hiltifag... a huge hilti FAN. I am a proud user of hilti tools is all i meant.
