Airbrush

Hi all I have 4 airbrushes. The problem I have is it sprats OK then all of a sudden no paint comes out but there is paint in it then it start to bubble up so any ideas I have sat and clean them over and over
 
You could try just running water through it - if it flows fine the. It’s the paint,

If it doesn’t then there may be a stubborn bit of pigment in the nozzle, if cleaned my gun before then had nothing but drama for a couple of days then it blows out and back to normal!
 
If I am reading right, it sounds like you can start out spraying fine, and then it stops, and you get bubbles in the cup. This would indicate a condition called "dry tip". Paint will start to dry on the tip of the needle as you are spraying, causing a small blob to form. This will in turn start to block the airflow coming out the front of the brush, causing the air to be forced back into the paint stream, causing bubbles in the cup... Most common cause is paint reduction, or lack there of ;). Try reducing your paint a little more, or upping your air pressure a little.

Hi how do you how reducer to put in say for example 10 drops pink so how much reducer you put in

If it is indeed tip dry then you’ll also need to ‘pick’ or clean the tip regularly, it’s the nature of the beast with waterborne paints. You can certainly minimise it, as Dave has suggested, by reducing more or upping the psi.
Start with equal paint:reducer and a psi set at 25, if it’s spraying fine then you’re good to go, if it’s not atomizing properly the add another drop of reducer. Mix and try again.
You’ll get tip dry, that’s almost guaranteed, but you can minimise it.
White seems more problematic across all brands.
Learn how to gently remove the buildup and keep in mind you could be doing it as often as every 20seconds. It’s caused by the air passing over the paint on the needle tip.

Also remember that the more reducer you use the more passes you’ll need to achieve the coverage you want. Newcomers often think you should be able to achieve full coverage with one pass, even with an unreduced opaque it will take more than one pass

Unfortunately there’s no formula to know how much Reducer to add. If you know the brush is clean, water runs through it well, then the paint is too thick and will need more reducer. Add reducer slowly until you can paint a smooth line that isn’t all broken up by starts and stops. It can be frustrating, but nobody can tell you exactly. Depending on the paint or even the colour, I will reduce anywhere from 1 drop of paint to 2 drops of reducer, all the way to 1 paint & 10 reducer.

First off what paint brand are you using?
Next why so much paint in the cup?
1 drop paint to 3 drops reducer is almost a standard rule of thumb. The Neo is .35 which means you may have to reduce the paint depending on what paint your are using. Com-Art you more then likey would not have to reduce unless it is white even then not too much to get good flow @35 PSI The the thinker the paint the lower the pressure the more you will get tip dry.
Wicker , CI you want to reduce some
But as with any help we need all the facts so paint being used. PSI your shooting at, If your using a stdio compress it might say you have 45 PSI with air off but once you hit the air on it may drop to 15 PSI. So as you can see the more you tell us the more and better help you will get.

Hi pal that was only for example I use createx and trident dna I do have a air compressor it has two gauges thanks for all that pal merry Xmas
 
Just wondering I have neo-cn airbrush what they like as I paint lures and squid jigs would a siphon one be better

That is still a personal choice being it would depend on it you have a painting jig set up for your lures or if you laying them on a table top.
Siphon feed does make for faster color changes that is why the T-shirt guys love them. But if your gonna stay with the Neo remember that the siphon feed version is .5 set up so less need to reduce paint as much.
 
Hi pal a silly question need when put back how far does the have to be out
You just need to gently move the needle forward until it stops snug against the nozzle. Don’t push it hard or the nozzle will be damaged. Just gently pressure with a little twist until it stops.
