Splitting Granite Boulders Using Feathers and Wedges

I split some of the large chunks of granite on my property using a hammer drill and some feathers and wedges.

The drill does most of the work. It’s pretty heavy so I just let gravity apply the downward pressure.

I wore a respirator because inhaling granite dust is said to be extremely bad for you.

Once the holes are drilled, I blew them out to ensure the wedges would sit in the hole at the proper depth. Then I used a 2lb hammer along with a set of feathers and wedges to crack the granite.

I repeated this process to cut the granite into even smaller blocks.

I’ll be using these granite blocks to create retaining walls and a small stone cabin on the hillside.
