[AT] O.T. Scribing on nearly flat rocks?

[charliehill]

Herb, do you have or know someone who has a glass bead blast cabinet that 
they use to clean up parts, etc or a  small sand blaster?
If so cut a stencil out of rubber and glue or otherwise fasten it to the 
rock and sandblast it.  The stencil will protect everything except where you 
want the letters.
Remove the stencil and glue and you've got it.
