I have just tried ferric chloride for the first time, it seems to etch
faster & better than ammonium persulphate.
Has anyone have simple plans for a spray etcher (only smallish)I would
like to be able to see the boards as they are etching without lifting
them out of the solution and thought if boards were mounted on an
angle a bit less than 90 degrees i could spray stripper from top edge
and still see board.
Any ideas appreciated.

p.s. my current setup is pyrex dish submersed in aluminium custom pot
sitting on hot plate.
