A friend of mine long ago claimed he used a week solution of nitric
acid for etching PCBs.

Has anyone here tried this?

I'm thinking I need an exhaust hood in my basement. I figured if I
use a fan then I have to worry about the fan being eaten by acid
fumes, so thought maybe I'd use my air compressor with a simple
homemade venturi pump made out of plastic pipe.

Whatdya think?
