Nozzle cap on airbrush

[Guest]

Hi guys, I've just got into airbrushing and have bought a as186 compressor and a cheap and cheerful gravity fed airbrush. The airbrush was working fine until yesterday. The nozzle cap was screwed on properly before and it was working fine, however now i only get air and no paint/water with it screwed on fully. In order to get any spray I have to loosen the nozzle cap and it's being temperamental. Does anyone have any idea why this is happening. Any help would be appreciated. Saj

It could be that the nozzle is blocked try giving it a good clean with some thinner then give it another go.

I don't think its blocked i've soaked the nozzle tip, the nozzle cap in vallejo airbrush cleaner for 8 hours. I've also thoroughly dismantled and cleaned the rest of the airbrush

Saj, these cheap Chinese ones can be a pain because their manufacturing standards vary quite a bit.

The way the airbrush works is that the passage of air through the nozzle cap creates a vacuum, which sucks paint through the nozzle & atomizes it into a spray.

If the nozzle cap & nozzle aren't in the right place, the vacuum won't form correctly.

Have a look at this link, the guy goes into this subject in great detail. I ended up removing the o-ring seal on my nozzle cap which solved all my problems.

Hope it helps, Patrick

No paint but plenty of air equals normally blockage Sajjad.

Sight from the back of the nozzle up against the light and the orifice if clear will be bright and round.

If not come back and we all will thinks of other problems it may well be.

Sorry to disagree Laurie, but in order to

have no paint at all the nozzle would need to be completely blocked. That's unlikely after an 8 hour soak in cleaner.

The answer is much more likely to lay with the position of the nozzle cap as this is vital to the creation of the vacuum.

Sorry, didn't mean to post that 3 times!

I have had a look at the tip and it looks pretty clear to me. There is a clear round hole when held up to the light. I'll have a look at that link as i don't think the nozzle is in the right position. On another note i'm looking at upgrading the airbrush as the couple of times that it worked I was very impressed with the results. What do you guys think of the iwata neo?

Haha sure patrick meant no offence But success!! I got it to work. Turns out i wasn't tightening the nozzle tip enough, i tightened it more than i dared to and hey presto it works! But i am looking to upgrade so any recommendations would be appreciated. It goes without saying but i appreciate the help guys. I've almost completed 3 models i have been working on and should hopefully be posting up some pics soon

That is ok Sajjad and I am so sorry to involve you. Unfortunately divergence of opinion can cause problems but we all have our own ideas which are based upon our experience. All we are trying to do is to get you up and running. In those circumstances all efforts are normally welcome.

Just for the record. The average problem with any airbrush not working is a blockage. At least with my way of working. Sometimes no amount of soaking will clear a blockage, The only way and the first port of call is to look through the nozzle to ensure it is clear. Sometimes you may have to resort to using a reamer which will physically remove hard paint which will not budge even with hours of soaking in Airbrush Cleaner. The cleaner may soften the dried paint but not loosen it from its grip in the nozzle. In fact it will in certain circumstances consolidate the paint.

If you are upgrading I would go for an Iwata or a Harder and Steenbeck. Having used brushes from both domains I can recommend either.

Harder and Steenback are great all rounders. Iwata especialliy in the higher ranges, are expensive, will give more options. I have found that Iwata do give a more smoother finish but are more decremental. Harder and Steenbeck probably better for those new to airbrushing. The H 7 S is also a more simple airbrush for cleaning.

Any more info just ask questions and you will get lots of answers. Also if you choose am model come back here to test those who have used it.

I have 'tidied' up the thread due to some duplicate posts.

Thanks Laurie, I will give the Harder and Steenbeck range a look. Already I have discovered the importance of cleaning an airbrush properly after use, otherwise you end up spending more time fiddling about with it rather than airbrushing!
