relief carving

["Susan" <zdome@xxxxxxxx>]

tap don't whack :)  and keep the angle shallower - i try
to avoid the use of points which can crack the stone
easily as well as scar it.  you can get grinding bits
for a regular drill which will give you more control
than the larger wheel - you also can get flex shafts
making it even more controlable - this is all supposing
you are not prepared to go and buy the more expensive
set ups (compressors/ airtools etc).

Working the piece in a sand bed will provide cushioning
- a sand bag might be tricky as you want to be sure a
piece that thin has proper support underneath.  The
larger your slab (or should i say sliver) the more
difficult this will be to approach with a hammer.  In
many ways stone is delicate and until you are familiar
with the properties of the type you are working with -
fractures will happen!

Good luck on your project
