Badger 100LG - first try

That "spitting" you are seeing is paint still on the needle tip after the last pass with paint.

A good habit to get into is to shoot the airbrush off into the air with air only and that will clear the paint off that needle tip. You can also train your finger to keep the air on and move the trigger forward after a pass with paint as this will do the same thing.

Remember to always hold the trigger all the way down as you cannot control the air flow by pressing softer as some people will try and tell you. It is far too imprecise.  

The "spidering" is caused from too much paint in one area so you need to learn to smoothly move the airbrush along and this will stop. The harder the surface, the more difficult it is to stop spidering. Just keep practicing, it takes time my friend. I still make those mistakes at times and I have been airbrushing off and on for 14 years. Practice makes perfect.  

Before starting your next line, spray onto a piece of paper to catch the spittle left in the nozzle.

Also, hang a piece of paper on a vertical surface. Use a pencil and draw some lines, straight, curved, squiggly. Add in some boxes, triangles etc.

Use your airbrush to trace the lines, fill the shapes, write words and sentences.

Work with different pressure settings, distances from the paper and angles of attack.

Use cheap acrylic paint. You won't waste a model and you'll gain the feel of your brush faster.

 

Repeat as needed! 

I have the Bager 155 anthem... ive had that problem where it spits out... if you look through the manual it said that at the end of your paint stroke you need to shut the paint supply off but keep the air on to blow that last bit of paint out.  if you do not then u get that small spit of paint at the beginning of a new stroke.

No, the low pressure is correct for spraying thin paints.  I merely meant that the pressure you cited indicated a thin paint.

So, if using this kind of paint its better to raise up the PSI?,

 I've understood that for fine lines you need thin paint and low presure.

I've been using a Badger 100LG, with both fine & medium tips, for about the last 2 years & never experienced the problems you describe.  I agree with others that the paint you are using is probably very thin, especially with the low pressure you are spraying at.  If you're new to using a double action AB, the spidering is a result of the paint being thin & you pulling too far back on the release trigger.  A double action takes some practice to get the feel.  As far as the spitting, you're obviously getting paint reservoir in the needle.  Have no idea what's causing that, but like others have suggested, I always spray air only away from the model before starting to paint.  Better safe than sorry.

I have never heard of Rotring ACP liquid Acryl, though the limited info I could find suggests it's more an ink than a paint. As such, it's probably a lot thinner than model paint and spraying this on paper is going to give somewhat different results than spraying paint on a model.

You shouldn't be getting any "spitting" when you press the trigger without pulling back. This suggests there is some build up of paint on the nozzle. This might be a result of the thin medium you're spraying at low pressure or it might indicate that your needle isn't fully seated in the "closed" position. Unscrew the handle and loosen the needle lock nut. Firmly, but gently press the end of the needle in as far as it will go and retighten the lock nut.

Two things I learned to do very quickly when I started using a D/A airbrush:

• "spray" a burst of air only, away from the model, then while there's only air going through the brush, move to where you want to start painting and spray away
• If there is no alternative to starting above your model, make absolutely sure the needle is in the "fully closed" postion before starting the airflow, otherwise it's almost guaranteed to spit.

 

Your "spidering" sounds like too much of a too-thin medium. It will respond differently with model paint, and you may need a little practice to find a lighter touch on the trigger.

Ouch, been there done that with the tip.

Never heard of that paint your using, but it sounds as though your paint is to thin.  And no it's not normal for your paint to "spit" after each line, this indicates a clog somewhere in your system.

I will refrain from giving any further advise.  MikeV will be along shortly, and he is the resident airbrush expert.  He will fix your problem lickety-split!
