Hello all, just joined the forum. I just turned 30 and decided to take the plunge and start making models again. I purchased a low end starter compressor with two airbrushes , I have run into trouble immediately, I tried one of the airbrushes and the needle looked bent from the start, it does not even spray clean water without the needle in place also. I moved onto the second airbrush, its an ab130, it works fine with water but not paint, I have tried thinning with water and thinners, from 10 to 30 psi ,as soon as paint touched it, it blocks. I have taken it apart cleaned it checked the seals and oiled the pats, but nothing works. Any advice would be great. I am sorry forfor the wall of text but am forced to use my phone, and it's not very forum friendly. Thanks in advance
 
Hi, First of all, welcome to the forum Neemo. This place is very friendly and no end of help and advice is readily available. You may need to make a few more posts before you can upload a pic so If you can answer a few questions that would help.

Ok What paint are you using? This may be the main issue..
Have you tried taking out the needle of the one that doesn't spray at all? A lot of folks use a magnifying glass or a jewelers loupe to check the tip of the needle.
Does the trigger move ok? Check that the nut that holds the needle is tight so when you do pull back on the trigger the needle moves with it.
Post pics of the airbrushes if you can, the more info we have the better.

I'm sure between us all we can get you painting very soon.

Well Il start with the good one, it sprays water as intended, thin lines or large heavy lines. I was using Vallejo pre thinned primer. Is it possible it's still not thin enough? the other brush let's call it brush 2 is completely blocked, it will not even spray water without the needle in place.
 
Welcome to the forum.

First off, primer is not ground fine enough for an airbrush nozzle, when used in a paint gun a 1.8mm nozzle is standard. An AB is usually .5mm or so. As you learn try to stick to airbrush specific paints . A cheap alternative is food coloring and water just mix it about the consistency of milk.

Seems a bit silly it's marked as ready to airbrush! I thinned it down by another 50/50 with water and had a bit more luck also had to turn the psi up to 35 or so, but it still started to splatter and paint two lines rather than one, maybe I need it even thinner still. Trial and error seems to be the way forward. I guess anything worth doing isn't supposed to be easy.
 
Welcome Home Neemo
First off what brand of paint are you using.
What brand airbrushes.
Never OIL an airbrush.. use super lube which is a water based lube designed for airbrushes , Oil can get into the air valve and than into your paint head.

Remember when asking for help we want all the information you can provide.It helps use know how to help you better .
 
So I played around with it a bit more, made the paint much thinner and getting better results. However I can't figure out the other brush , the needle is not visible so I assume it's bent and not fitting through nozzle , however even without the needle in the airbrush the water does not spray, why is this?

If the needle isn't visible there is a good chance it hasn't been placed far enough into the nozzle, this could be due to something on the nozzle, you'll need a magnifying glass to check that out.

Secondly, as mentioned already, thinning paint does not thin the pigment, the pigment remains the same and thinning heavily pigmented paint will usually cause pigment migration or or separation of the paints elements.

@Mr Micron, he does mention in the third post that the paint is Vallejo airbrush ready primer, however, I've read of this somewhere else recently and as "wmlepage" states it's only airbrush ready for larger tip and nozzle sizes exceeding 0.5 da do ron ron's.

@Neemo83, check out Mitch's strip down vid and remove the needle completely to inspect it, try to get a good look into the nozzle to see if there is anything that could be blocking it, there could be some dried paint or small debris from the factory since quality control with cheaper brushes is almost nil.

As I understand it you want to airbrush to do your models, if you want cheap with some degree of certainty I would recommend you check out either the Neo for Iwata or the Harder and Steenbeck Ultra, both of these are ideally suited to your purpose and carry the relevant guarantees from both companies, this would save you a lot of time and headaches, and to further save money and time cleaning you could do your priming from a simple rattle can and use your airbrushes for finishing.
 
I'm also a newbie, but I have been using Vallejo primer (white, grey and black colors) direct from bottle and using chinese airbrushes with 0,3 and 0,35 needles (bd-132 y bd-128) without no more problems that the usual tip dry
 
godi, beware shinese aibrushes are most probably like the forbiden word that starts with that letter.and i talk from experience this pieces of #$%& have rubber seals which in time will be devoured by any paint that is not water based(watercolors or gouche),as a matter of fact even inks can eat the seals(talking from painfull and expensive experience) and you´ll soon be having paint in the trigger chamber.and to make it worst you will be expending a lot in spare parts or buying a new one.so i implore you that you should buy a neo for iwata or a paasche vl or millenium,if you are in a tight budget.

neemo83 the best advice i can give is that you should get a magnifying glass so to confirm my suspiscions.you´ve got a bent needle. and the best thing you can do is to replace it.do this before you break the tip.having two lines is a clear indication of it,in the case of the paint use a 5 to 1 or 10 to 1 relation,always(also from sad experience).try this at lower pressure and if the double line disapears...you are a lucky guy!!!

hope this helps,i really do!!!
