To get an airbrush rig on the table top, I got to combine two of the great things in life... modelling, and home improvement stores. For this particular build, I had a few criteria: keep it multi-purpose, portable, and suitable to long painting sessions (my preferences), and keep it quiet (my wife's preference).
This particular setup has a few bells and whistles that are not required for basic airbrushing...I will make note of those optional components when they come up. The order I list them is the order I connect them in the final rig.
