Airbrush spitting

I had this problem yesterday morning while pre-shading.  It just started with my Badger 200 about 5 minutes into the paint session with a mixture ratio I had used many times and a good needle.  The cuplrit?  Humidity was at about 60% in my basement and I had my moisture trap on the hose for my Paasche VL.  Once I put the trap on the hose for the Badger and cycled some thinner through the unit, the problem went away.  Other then that, its usually the paint is too thick for the needle setting or I am ham fisting the trigger while being to close to the surface. 

Try lubricating the needle. This also helps with the tip dry problem.

Just need to find the secret sauce.

 

That is an ancient Chinese secret... LOL! I couldn't resist saying that. 

I had a similar situation recently with one of my airbrushes. After really magnifying the tip of the needle, I found that there was, what looked like a tiny hook or split in the very tip of the needle, this had collected a small fiber which was collecting paint as the paint was sprayed and the paint would come off that fiber as chuncks or globs onto the paint.

I tried, if nothing else I'll have a spare. I should get the new on in 2 to 3 days and I wasn't much.

The needle can be fixed....

After looking at the needle under a magnifier I noticed it was a little bent. I ordered a new on so I can get to my camo in about a week or so. We'll see if that does the trick.

Damaged packing nut will cause that also.

I get spitting from a dirty nozzle- incomplete cleaning from a previous session.

Often thats water, which the compressor forces into liquid from air.

If you don't have one, get a water trap.

Hmmm, I'll have to take a look at it, that may be it.
