I built a quick looking enclosure for the sprayer out of a plastic storage bin that I had laying around so now I can start to test with paints, and not have it make a huge mess. I ran a test today with the following:

Setup:

Results:

Surprisingly much better than expected. Nozzles had a pretty good misting spray; however pretty wide angle so quite a bit of wasted paint. Also the paint was a bit spotty meaning it wasn't atomizing enough, so maybe smaller orifice, more pressure. Could have eliminated 2 of the sprayers. Need the ability to cut of the fluid rather and just the air. I do have a valve on the fluid line but I can access it from outside the container.

Go Forward To do:

• Add a fill line to the container
• Solenoid valve at the fluid exit at the container? https://www.amazon.com/DIGITEN-Solenoid-Connect-normally-Closed/dp/B016MP1HX0/ref=sr_1_2?s=industrial&ie=UTF8&qid=1483492282&sr=1-2
• Probably better off with a rigid style sprayer main line to simplify testing. The flexibility of the current one make it a pain to work with. Switch to rigid then maybe consider something like this down the road to try and reach the tougher places of a part: https://www.amazon.com/Orbit-Arizona-Outdoor-Extension-10056H/dp/B0013I96VC
• Need more flexibility with nozzle choice. So I am switching to a more universal screw on nozzle setup with 10/24 threaded nozzles. Major next step is to build this setup.
• Also need to start thinking of a motorized turntable style system to spin the part. I am thinking a small geared DC motor with a small metal tube extension off the shaft. Place the motor on the top of the enclosure and attach the part to the shaft extension hanging down into the container.
