Boulder Stool

How to drill holes in rocks is the question I had in mind at the beginning of this project. I want to do more stone furniture projects and I have access to a lot of low cost rocks so I have been experimenting with small rock diy projects like this stone stool. I used my ryobi hammer drill to drill 3/8" diameter holes in a granite stone and then used Quikrete Anchoring epoxy to glue in 3/8" steel rods. This was a really easy and fast DIY project and I am starting to brainstorm other projects made with real stone.

STEP 5

Shape the steel bars into legs and trim as needed. Once the legs are shaped as desired, flip the stool over so the seat is upright. Pull the legs out as needed until the stool is level.

Secure the leg ends together by wrapping metal wire around them.
