OK everybody, here is the photo etching information/question/comment/idea thread.
First item is that I remembered a cool website I found a few years ago. Click on the link below and page down a bit and you will see links to this great guy's home etching set. He has done a large amount of research and development on etching processes. I almost dove in using his ideas but decided against it due costs and chems in the house.

PS It seems Randy has hit hard times based on what he wrote on the front page. Let's all hope he gets going again soon.
Great article, thanks for sharing.
I think I will quit crying about the high cost of photo etch sets now.
