PK, did you make that bottom unit? If so I would love to see how you made the needle assemblies.
I need to make a fogbuster clone, just 1 valve. The usual air valves are all wrong direction, that don't like stuff going the opposite direction at all. I want the droplets, not a fog. And it will need only 10-15 psi at low volume, like an airbrush compressor volume is adequate.
