Anyone used a Aztec A470?

[gainsy]

Hi
I am new to air bushing so a friend has lent me a Aztec A470 airbrush to practice with
I am using Faskolor acrylic paint
So far i have had no luck with it really, paint seems to come out when it feels like it, this stuff say's it's ready to spray so tried that & nothing came out, so watered down a tiny bit, got a little coming out, watered down some more, no change really, watered down loads & nothing came out
It sprays water through the bottle no probs
Took it all apart & soaked it all last night so hopefully i will get better results today
Anyone got any good advice on the brush?
Got no idea what needle size is in it as it doesn't say nothing on it
Have been practising on some spare lexan i had but don't fancy trying my new shell until this thing is working properly
Or should i just send it to Jon for a pro job
Cheers
Gainsy

I used to use one prior to the Iwata.

The nozzles are prone to build up and paint blocking if not kept spotless. If you're careful you can gently tease out the sprung loaded needle to clean them properly. Gently pull on it from the back of the housing, it will give eventually and pop out. Then once it's scrupulously clean press it back in gently.

Hi Ju
The compressor is a Badger BM250 1.8 bar micon minibox & the tip is a grey colour
Pulled the needle out last night & soaked
Have just tried it again with undiluted paint & it seems to be working much better, not perfect but that is probably me
Will get some more tips next week & keep trying

I had one, i have to admit i used it once and that was all i could cope with.

Have a look at these AB brushes at £30 an with replacement needles freely available they are worth a look

There's your problem I think. 1.8 bar equates to about 26 psi (unless I'm misunderstanding the conversion in google! You need a good 40-70psi

Does anyone else have a better compressor that you can try?

Ahhhhh
Did wonder about the pressure
Don't think i can borrow 1, might be able to hire 1 in the week to see if it improves
Seen a few on ebay so might get myself some new kit

I don't think the pressure would be the problem if the conversion is correct? or at least not the only problem. (dont get me wrong the compressor is no way ideal but should work)

I spray paint alot lower than that sometimes below 10 psi with no problems (different airbrush tho) I think that you are likely to have a blockage in the nozzle, I personally would try spraying some airbrush cleaner through it and give it a thorough cleaning if that doesn't work then I would try a different compressor if possible (doesn't have to be one designed for airbrushing any good hobby/work compressor would do the trick).

Good luck and let us know how you get on.
