Here’s some engraving I did recently on the LCD border for The Clacker PC I’m sure any “real” engraver would laugh at this method, but I think it’s a great trick for the hobbyist to add some eye-candy to a piece of polished metal.
(The brass still needs to be repolished in these photos)
All you do is lay a piece of sign vinyl or clear, thick packing tape onto a piece of polished metal, draw out a design, cut it with an Exacto knife, weed out the tape from any areas you want etched, then run over it with a sandblaster (I just use a Harbor Freight handheld sandblaster gun, no cabinet. Grit goes everywhere but it works).
Happy Tinkering,
