Adam,

That etching machine looks great. You do nice work. 

I have always felt that spray etching is the way to go. My spray
etcher will etch 1 oz. copper in 3 minutes with fresh etchant and
about 5 minutes when it's almost used up. This is with ferric chloride
at 110 degrees F.

Keep us informed on your progress. Thanks for sharing the information.
