I have a large amount of raw Granite (http://tanbrown.org) on my property, left over from quarrying operations from the last century. I want to split it and (http://maplered.com) use it for steps, walkways and (http://maplered.com) retaining walls. Problem is, I don't know the first thing about doing it. Can anyone help? I REALLY appreciate any advice, or suppliers of appropriate tools.
