Over 50 climbing bolts breaking in sandstone - SLOW MOTION COMPILATION
🕑 Added 2019-12-25 14:30:59 +0000 UTCWe can learn so much in watching bolts break in 5 minutes about the nature of how they work. You can see that they don't always come out of the rock, but the hangers come off, hangers snap, welds break, and bolts snap. How much force did they come out at? The Bolting Bible will have that soon but other than short mechanical bolts in wet sandstone, the forces are higher than climbing gear is rated for... so super good enough. Why test them? So we can learn to trust them, highliners can put in fewer per anchor (we don't need 4 anymore guys!), and answer soooo many questions our community still doesn't know the answer too. Learn bolting in the Bolting Bible. 2020 version coming out by March 2020. Bolting Bible is a free book and the break test project is about a $10,000 project not sponsored by anyone or any company... donations greatly appreciated. We do it because we are nerds who love to learn. With Bobby Hutton BOLTING BIBLE https://www.slackademics.com/boltingbible
