One of the things I need to work with stainless steel is a way to mark the blades, since my tang stamp is not really appropriate for stainless.   One of the standard methods of marking stainless is electro-etching.  There are plans floating around the internet for building an etcher, so I pulled down the parts list and got around to building one. 

They didn’t have the case that was on the parts list, so I decided to improvise. I built the etcher in a 1 quart paint can from the home improvement store. It didn’t leave me a lot of room – see the video below of how it came together.
