My AB gummed up something awful; Model Air and Model Colour paint

[Guest]

Steve. After you clean the brush & connect up if you pull the trigger back (no paint) do you get a regular supply of air ?

Is the paint drying off quickly in the cup ?

Have you any other paint than Xtracrylix you could try ?

m1ks: Many thanks. I will do these things tomorrow and report.

You also said: "The cost of the brush shouldn't be a problem unless it's been behaving this way from the outset which might suggest a faulty manufacture or part problem." At first it seemed OK: I was using Vallejo "Acrylic Polyurethane Surface Primer 73.601" although that airbrushing always seemed to take a rather long time to cover the part compared to videos that I have watched.

If I cannot resolve it myself (with help here) I will return it to the seller and ask for a replacement.

tecdes: Yes. Pulling back the trigger produces a strong flow of air, and also cleaner (I can see the stream). Its when the colour paint is used that it actually clogs. I'm pretty sure that the nozzle covers are not clogging, nor is the paint drying in the cup..

On trying another paint, I have one bottle of Vallejo Model Colour but as I have been told that is not ideal for airbrushing, I will get a pot of a Vallejo colour and try that. However, please note above in this message my early use of Primer.)

I did mk1s's tests and found no faults. I also took the opportunity to minutely examine the nozzle to check it and its surroundings and the needle to confirm that all were 100% clean and they were.

I rang the supplier, Yorkshire Clockmakers trading as airbrush-pro.co.uk offers airbrush airbrush compressor autoair paint airbrushes createx paint and they were flummoxed, especially about the way the primer did work albeit seeming to take a long time to build up coverage, and the fact that for some tests I had over-thinned the paint. He is sending me a 0.5 needle and nozzle. If it works it will probably suit me since I am not likely to be doing fine lines in the near future.

Be interesting to know how it goes Steve.

Got to say you have patience if it had been me it would probably have been in the dustbin. Or perhaps before that I would have been banned by the Ladyship & living in the greenhouse in disgrace.

Yes, the Memsahib did comment along those lines!

It works! Cause = mystery!

[Guest]

Not familiar with your Airbrush Steve. But mine after carefully adjusting the needle into the nozzle I turn a thing which clams the needle into position. I just wonder if the needle had not been clamped as it should be in which case it could perform some of the things you have had problems with. If it is not tight it may work first time but perhaps then moves back into the nozzle & the trigger will not pull it back.

Great bit of speculation what !

I learned about the clamping thing you mention from videos, and it was tight. I also could see the needle moving in and out when the trigger was moved. It's a real mystery because it sprayed cleaner and primer OK.

Obviously divine intervention.

Could do with the address to that source Steve.
