Etching brass plates

Recommended Posts

I spent 40+ years servicing the chemical machining industry. Generally such plaques are made by applying an acid-resistant image, either via silk screening or a photo-sensitive lacquer, and are then etched using ferric chloride as an etchant. If you go to this link and scroll down, you'll see a picture of an old and newly manufactured ID plate for a Packard IM-357 marine engine. As I remember, the cost was about $100 each for 3 plates. PM me if you wish and I can probably get you the vendor contact information.

Chris, Thanks for that link. I may yet try this at home! What a great bunch of tips you have there. Is it possible to read the archives of other past articles online as I could only access the page you sent?
