Rockface granite

Quoted text begins.how do you rock face 1 1/2" thick granite?

Thanks, Bob. As John and George have pointed out, it's not impossible but
not easy without the right tools. JVC's Beaver is here: http://tinyurl.com/d4ty4

If this machine is out of your budget, then at least a good hand set and
hammer are necessary: http://trowandholden.com/sculpting2.html

Lay the material in a stack, or on a flat slab so each piece is well supported.

When I'm making rock edged slabs, I like to wet the material as I'm working.
I keep a hose trickling so I can wet underneath each slab before striking it
with the hand tools. The water helps support the material and makes it easer
to split in a controlled way. Sounds crazy, but it works. I wasted a lot
of stone before I accidentally found this method while working in the rain.

If the countertops are made from gneiss (nice) then they will split easiest
along the stripey grain. Do this first, then split across the grain. Split the
larger pieces by tapping gently with the hand set and hammer along the required
line. If a piece starts to split at one end, hit the stone at the other end.

If you have trouble doing it this way, then you may need to use a diamond
saw http://tinyurl.com/7ovnu to help control the spltting. Split larger slabs
into lengths first, then mark out an additional 5/8" longer than the
required dimension. Cut half way through the slab and snap it off.
Use the hand set and hammer as described above to pitch off the excess stone
back to the required size.

Good luck,

Simon
