Homebrew PCBs

From: grantfair2001 
  For air I thought I would try a portable tire inflator from Harbor
  Freight, or perhaps an old Gast vacuum pump I've had kicking around
  for years, if I can figure out how to use it as a compressor. Failing
  that a buddy has offered an aquarium pump but my etch tank is a 34
  quart capacity Coleman chest cooler, so I am unsure it will have the
  needed air volume.
I believe shop compressors create some oil mist... You might want to try bubbling through plain water to test your compressor, before you foul up your etching solution with oil.

Cheers,
