Dear Pat, I am working on the same endevor. I have found The
Jewelry Engravers Manual. I found it at Powells Books here in
Portland, Or. Perhaps you can find it elsewhere. Here is the
The Jewelry Engravers Manual
R.Allen Hardy & John J. Bowman
Dover Craft Books
Dover Publications, Inc. New York
It covers everything in great detail, and seems quite through.
I’ve just started it and can’t claim great results but the fault
is not with the book.
