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."

Bad guide

[s0rbix]

This is a terrible guide. Several times he says "make sure you know what you're doing" but offers no help or explanation. It is poorly worded and offers little guidance. The pictures do not help at all, either. Does anyone know of a better guide for electrolytic etching?

Tape, knife, and bead-blaster

[RiffRafff]

Cover the "canvas" with masking tape. Draw your design. Cut out your design with a sharp X-Acto blade. Etch the exposed design with a bead-blaster (like a sand-blaster, but uses smaller, more uniform glass beads, and doesn't eat away as much, as fast).

Been doing this for years.
