What is going wrong?

Hi

As you can see in the attached videos Im struggelig with my airbrush and paint.

I have tried with Vallejo Game Air and createx colors. (Thinned and unrhinned, and thinned as hell) same issues every time.

Ive been told it could be dry tip syndrome, but really? After 10 sec? How does anyone get anything painted then?

Is it my airbrush theres to cheap?

This is the brush: http://www.profi-airbrush.de/CAR-DE...ben-19-er-Set-in-Geschenkverpackung::143.html

Im about to give up on this hobby.

That is certainly not a problem with tipdry. It probably is one of two things:

-There is some dirt in the nozzle blocking the paintflow resulting in this "sputtering" (make sure it's 100% clean and maybe leave it to soak in some airbrush cleaner overnight)
-The nozzle or head assembly leaks or doesn't fit right resulting in air starting to circulate which in turn results in this sputtering.

I had a look at the link and going from that I personaly think it will be the last of the two options. For that price (the full none reduced price) you'd get one reasonable airbrush from one of the "A brands". You can't expect to get a gun that performs well for the price of this complete set. I tested some of these cheaper guns and eventhough you can get lucky and find a decent one there is certainly no guarantee.

These sets are nice to get a feel for airbrushing if you don't wan't to spend a lot of money when starting out (or aren't requiered to do detail such as stenciled airbrush tatoo's) but if you want to get more serious I'm afraind it will also requier some more serious investments

Hi

Thanks for the quick answer.

Why do you think that the flow stops as you can see in the videos? Im releasing the same amount of air constant.

Why airbrush would be recomented for a beginner? Iwata eclipse?
Prefeer if it can work with the compressor from the kit.

You might be releasing the same amount of air but the air circulating within the head disturbs the flow of the paint (at least thats a possibility... and considering the brush the one I think most likely ). Seeing the vids I recognised the sympthomes from problems I have had with airbrushes in the past.

The compressor in the kit wil almost certainly be fine (the only thing requiered from it is that it generates airflow ) and will work with any airbrush.

I myself like iwata's but there are as many oppinions about this as there are airbrushers. If possible visit a specialised airbrush store and try some guns else do a search and read up on the most common brands.

Other brands beside Iwata you could have a look at are Harder and steenbeck (H&S) and Olympos

The hole on the lid needs to be open. Have you tried it without the lid?
Holding the trigger all the way back as long as you are could cause alot of issues. I do not not see any trigger motion. Down for air, back for paint, forward to stop paint, then up for air off....

I think a dirty nozzle is definitely partly to blame. In the first video where it shows the paint spidering, it is only spidering on one side, that is an indicator the nozzle is not clean. The needle not seating properly because of that means the suction isn't right. I expect you are having to pull back pretty far before paint comes out, you are getting nothing until the pressure builds up, then paint is coming out but not in a controllable way.

The brush could be an issue too as haasje says. Those guns are very hit and miss, and made of cheaper materials. Even if they work well at first, they often don't last long, nozzles can be soft and get damaged or flared easily, o rings and seals give out etc. The only way to know for sure is to make sure you get that nozzle 100% clean, you may have to soak a couple of times. Before adding paint again use water, can it spray an unbroken line, a perfectly round dot? If it doesn't, it def won't with paint.

If you do decide to upgrade, the hp-cs eclipse is my recommendation.

Being that the spray goes for a while thick and then thin you are having the paint begin to clump in the nozzle. This could be bad seals in the brush causing air to leak inside the nozzle and start to dry the paint. Once the clot passes through the nozzle you go back to the full paint flow. It could be improperly mixed paint and reducer or reducing with the wrong reducer. If it were a dirty nozzle from dried paint it would be restricted flow constantly.

Check all seals and reduce and mix the paint properly and strain through some pantyhose across the top of you bottle.

One last thing could be way too high of air pressure across the tip and needle to it is being forced into the paint chamber drying the paint inside the nozzle.

Judging by the sound it sounds like paint clotting inside the nozzle.

Yeah I'm think dirty nozzle - had this issue before and it was a pain to remedy lots of cleaning to be done

I hate to disagree with airbrush dreams, but this has happened to me before with a dirty nozzle. But it could be a brush issue too. If you can get that nozzle good, you'll know if its a brush issue, or it could be a combination of both.

Not arguing. Just wanted to explain my reasoning. If it were dried paint inside the nozzle the restricted would be continuing constantly and not start and stop. My thought is the paint is starting to gum up inside the tip of the nozzle and when that gummy paint passes you then have your full amount of paint back. If it were dried completely and hardened then the hard stuff would blow out, it would just force you to pull the trigger further and further back to let the paint to flow at all.

Air is only supposed to flow over the tip of the needle and drag the paint through the nozzle. If the air is flowing inside the nozzle it will begin to solidify inside the nozzle till one of two things will happen. Either the paint will thicken grill there is enough back pressure and it will blow the clotting paint out or it will harden till you begin to have no more paint shooting out and bubbles in you paint cup.

By all means cleaning the nozzle is a good place to start.

Also look at the whole in your cap on top of the cup and make sure the breather hole is fully clear and not clogged. This would cause a vacuum effect and interrupt the flow of paint.

No worries airbrush dreams, just a different view based on my experiences.

There is a mixture of a few things not goin right..personally I dont like silent or instant compressors..I feel they often drop to much in pressure so generally i compensate when using one and pump the PSI a bit more..What PSI where you running in that test...What was its lowest drop?..If not maintaining at least 30 PSi I wouldnt use it for a testing the airbrush purpose..My airbrush (badger Anthem) will vary greatly in the way it sprays when placed on my shop compressor with a nice constant buffered air supply compared to it running like a cow on my twin silent compressor..plus the fact it likes a bit higher pressure than what your likely using..Secondly, take of the nozzle and expose the needle..Does it paint any better..Some shrouds when the begin to block or gum up with potentially create splattering...So can a dirty nozzle and sometimes no amount of cleaning or solvent or ultra sonic baths can remove it and a reaming of your tip becomes a necessity. Various ways to do that safely or you can like many use an old needle to gently ream the tip...A split in your nozzle can also cause the issues above or a head assembly thats no sealing well and thats where bees wax comes into it or a little dab of vasoline. Could be gummy or cruddy paint, always stir, shake and strain your paint well..What it is is general teething issues, bit of the brush maybe, bit of your own ability maybe, or just a dirty gun ..

Try this guide out, generally helps solve or at least identify what causes what issue...

Also could an admin please move that post to the appropriate section, cant be found in Airbrush Guides and should sit in the trouble shooting section, asked a cple times but I think it would help more peeps solve their own issues if they could find it...Pretty Please

Because you said pretty please, its now moved, if you tag an admin we'll action as deemed necessary
Great info as usual

I have one last suggestion. If the brush you have came with a spare needle and nozzle and you have not used them yet, try switching them out and see if your issue continues and then go from there. At least that would tell you if it is the nozzle or the seals. If it is the nozzle than the problem should be solved if not than it is the seals or the paint. I didn't hear any fluctuation in the air coming from the tip of the brush so I don't think it's the air source. Even if it is a diaphragm compressor with no regulator. All that would do is cause a pulsating air flow, but it would be constant not intermittent.

To follow up, I bought a H&S evolution and the problems seem to have vanished. So now im on to see some tutorials about beginning to airbrush... does anyone have any suggestions to where its best to start.

And hey bye the way, thanks for all the advise...

If your problem returns the you'll know it's not the brush and you'll need to check your reduction/pressure/cleaning.

As for tutorials
http://www.airbrushtutor.com/

Register there, you'll have access to free downloadable exercise sheets which help build muscle memory and confidence.
Apart from exercises there are a couple of free projects.. 'the eye' 'cameron' 'leopard'
All of which may seem almost impossible when starting. But they are do-able. The are also some excellent paid tutorials.

Now you've got the good brush, you'll have a lot more fun
