Electric jackhammers work very well on concrete -- don't see why they wouldn't
work on stone, though it might take more time.
You might also consider using an electric drill with what they call feathers
and wedges.

If you can drill holes all around the protruding rock, then put in the
feathers and wedges, then tap in the wedges a bit at a time, you might
be able to pop the top right off.
I used these things to break up some boulders in my basement and I was
amazed at how easy it was. On straight-grained rock like granite, the
results look as though it was cut with a saw.

| I've used the electric hammers to break through field stone and
concrete foundations. Worked well in the concrete, poorly when
you hit a stone. Go for the biggest you can get, or and air driven
jack hammer if you can afford the rental cost. I've been successful
in digging some of these out (ones about the size of a kitchen stove)
but it is a lot of work.
You know that if you manage to get the top off the rock mother nature
will just heave it a little higher at the next frost just to p*ss
you off.

| 1010.3 | Score it | PUNK::SUNG | Hoopbusters - de agony of de feet | Fri Jan 23 1987 11:15 | 6 |
| The method described in .1 was recently featured on This Old House.
They recommend a score line if you want the rock to break on an
exact line. The score line is created using a chisel and hand sledge.
Be sure to wear eye protection when you do this.

| I rented an air hammer to bust apart a 6x3x3 block of concrete that
used to be my front step. It worked well, but it was HEAVY. It
took about 5 hours and all my strength to finish the job. I'd say
that if an electric hammer will do the same job (I've never used
one) try it even if it takes a little longer.
Btw - The weight of the air hammer was at least 50 lbs when I started
the job, and 90 lbs when I finished. At least that's what it felt
like!
Lastly - whatever you use, wear eye protection! My goggles fogged
up from sweating and I decided to take them off. It wasn't more
than 5 minutes later that a peice almost got me. I always wore
them after that .....

Obviously not a diver... You're supposed to spit on the inside
of the goggles to prevent it from foggin up.
