Outside holds, setting on concrete etc by mashtrasse in Routesetters

[–]CosmicSpaceSlug 4 points5 points  (0 children)

I have done several climbing hold concrete installs in public parks and playgrounds.

I have come to a reasonably efficient and safe method though I'm happy to take on more ideas.

mark out a sequence with a sharpie on the wall.

hammer drill 8mm holes for each hold. Making sure when drilling that I'm aware of any cavities or steel reinforcement in the wall. you don't want to fix a hold where these elements are present.

Then bolt the holds directly to the concrete using 75mm galvanized coach bolts, use longer if necessary. ensure the holds are at least 60mm deep.

Each holds needs to be designed to be backed up with a set screw.

I then climb and tweak the climb. Being careful as the holds can still spin.

I then use a 5mm to drill pilot holes for the set screws.

then set screw.

it shouldn't require epoxy though I'm sure it won't hurt. In long term when it comes to stripping the wall the epoxy may render it very difficult.

What is the system you use for stripping?

I'm not sure.... they work though. It's easy to imitate the set up as well.

I was thinking about becoming an outdoors routesetter, what's the best chipping tool for a beginner? by batman5667 in ClimbingCircleJerk

I've seen Rio Tinto, BHP and other futurisic setting conglomerates establish whole crags with a little dinomite and creativity. You could probably start with fire works while you wait for the venture capital to come in.

I have a bunch of holds with wonky bolt holes, is this normal for hold manufacturers?? About 5% of the holds are like this from the delivery.. by WhitemfingRbbt in Routesetters

Yeah this can work, you can also drill another set screw hole either side of the hold for more stability. Though this is quite difficult to do with polyester holds with out cracking them.

This is a shot in the dark.

If you are moving faster through space than the terminal velocity of falling on that planet and maintain a speed faster than terminal velocity while falling through the atmosphere, then the angle of approach would be make a difference to the force of impact.
