The Black Art of Photo Etching 
I am convinced that photo-etching is somewhat of a black art – possibly even a form of alchemy. I say this because, like the alchemists, I started this process with some metal, some nasty chemicals and an idea. And, like the alchemists, I ended up with less of my original metal, a quantity of different nasty-looking chemicals, and an idea. And, an identical process does not always yield an identical result.
Actually, everything turned out reasonably well. I was left with a large quantity of parts, and a bucket of salt water and rust. However, there are a few things that you may need to deal with that are not included in the main instruction sheet.
In the next run, I’m hoping to have the process control a little better, for somewhat more consistent results.
