Well, its a bit of a long way around it, but you can do the full engraving effect by following any one of these tutorials:

http://www.photoshopcafe.com/tutoria...d/engraved.htm
http://www.screaming-art.com/t_engraving.php
They vary a bit in quality and scope, but they all get you there eventually.
