Very nice. Its more or less the same process (different chemicals though) for etching brass plates. Was researching it earlier in the week to see if I could fabricate my own data plates for another project.
If you were to soak a much longer track section in a larger vat, would it simply take longer due to the current in a bigger volume of solution, or would you need to increase the electrical charge to maintain the load?
