wondering if there any knowledge hearabouts regarding splitting granite
ledge. I have a spot I would like to put a hallway to a future spare
room. about 4-6 feet long it is only about 6 foot high. Ledge is solid
dropping right to left, but nearly level in this spot. I have a mid size
Bosch rotary hammer and am not averse to renting a bigger one if I need
to. I am not in a great big hurry, and since it is under the house,
blasting is not what I am going to do. Anyone done much of this? Any hints?
