Ryan Jenks, a mostly fearless, generally hilarious and always high energy guy, is behind “How Not to Highline” (YouTube and website). He somehow manages to combine humor, science, and exciting real life testing to shows some of the break limits of climbing gear and rigging.

Ryan wrote a very detailed e-book on bolting, called “The Bolting Bible”. It's all here: ethics, metal types, rock types, hole drilling, mechanical bolts, glue in bolts, different types of glue . . . 130+ pages, 400+ photos, 200+ links.

If you ever plan on placing a bolt, this e-book will help. And for the rest of us who rely on bolts and really hope they are properly placed, this is a great tutorial on how they’re properly installed, and occasionally what to look for when they’re not. It's also updated regularly with new testing results and materials.

While you can download the e-book for free from the link below, Ryan would certainly appreciate it if you could make a modest donation so he can continue to produce more high-quality free educational material that benefits our entire community.

Note: Placing bolts is a BIG responsibility. Follow these best practices:

• Practice bolting somewhere obscure no one will ever see or use, not at your local crag. 

• Have an experienced person check your work. 

• Study and follow bolting regulations from land management agencies. 

• Don’t add bolts to an existing route.
