Our power is intermittent, so I decided to try hand-engraving a ring with some home-made tools fashioned from broken tungsten carbide drill bits. Not the worst ring ever, but I could sure use a book on the proper technique for engraving. Hint, hint.

I can´t help you with a book, but I hope you are alright and on power again soon!
We're good here. Thanks Yvonne!
