Electrolytic Etching, For What A Dremel Can't Do

Dustin writes "A lot of people modify computer cases, often requiring them to cut intricate custom designs in sheet metal. For most, there is the Dremel tool. But sometimes, that just isn't good enough. Possibly due to an insanely complex design, or unsteady hands, a Dremel just might not cut it (pun honestly wasn't intended). JimBob, a member at OverhauledPC.com, has a much better way. Using readily available salt water and electricity, his technique is much easier than trying to cut patterns with a rotary tool."

Excellent...

Now, instead of merely cutting myself, I can electrocute myself as well. I love case modding!

Can also be done in a much simpler...

...(and safer) way with FeCl3 (ferric clhoride), the very same stuff used to etch circuit boards by hobbyists arround the world. Since it attacks most metals, you can do complex chemical etching with it: i've seen small plates with logos done that way - you just have to find a way to mask the design somehow. It requieres no electricity as well.

FeCl3 is cheap, relatively safe (don't eat it kids!), and easy to handle. It stains like a bitch though, and will attack most metals so be careful with spills.

Try it without the chloride.

That, or NaCl sans sodium. Gotta love those chlorine fumes.
