Creating Climbing Holds
-
1
Find a few shale or sandstone rocks that have at least one smooth side. You will need 1 rock per climbing hold.
-
2
Set the rock on a flat piece of wood. The wood should be at least 1 inch thick. Use the wood to support the rock as you drill a hole on it.
-
3
Clamp the rock to the piece of wood. Position the clamp so the middle of the rock is not covered.
-
4
Make a hole through the center of the rock using a power drill and carbide-tipped masonry bit. The hole must go all the way through the rock, so you might end up drilling into the wood the rock is clamped to.
-
5
Drill a hole in the wall where you want to attach the climbing hold. The hole needs to accommodate the bolt that you will be using.
-
6
Hold the rock on the wall so the hole in the wall and the hole in the rock line up.
-
7
Place the washer over the hole in the rock and insert the bolt through it. Use a wrench to tighten the bolt in the wall.
