That's awesome. Can't wait to see it! Just wondering about the etching solution. When I tested my etcher I used electrical tape as a stencil and water with a few dashes of table salt for the solution and a q tip as the contact or whatever its called. I was very impressed with the results. It was able to etch pretty deep and it blackened nicely. I didn't want to get too fancy till I could prove my etcher works. My actual stencil will be the true test. How much better is the proper solution?
