Are airbrush nozzles universal or do you have to buy the same make to fit your AB ?

They vary a lot. Generally you will have to buy one specific to your brand, and usually model of airbrush.

You'll also need to match needle size with nozzle size Alan.


What AB do you have? Sometimes it's actually cheaper to buy another airbrush than get spares or additions.

Well I can't get a nozzle for mine Patrick and it's a cheep expo pistol grip , I dug out the instructions and it states it can spray within 0.05mm but it doesn't spray that thin which would be ideal for what I want it for so I geuss I'll have to upgrade 


so it's research time to find one that actually does spray that fine

What half a millimetre ? , I think the thinnest I've got is about 2mm

All manufacturers will state the thinnest possible lines are achievable with their particular airbrush. That don't make it necessarily so! ;)


The advent of acrylics has led to using low pressures, which in my view makes thin lines hard to do. 


Higher pressure (+30 PSI) and a light touch on the trigger produces thin lines with greater ease. Admittedly, that's with those despised enamels! 


If you're looking for an airbrush with a smaller needle/nozzle combination, you could consider the Fenghua one that John sells. I've got one & I know Graham rates his one.


I bought mine from Amazon, simply because it came in 3 sizes; 0.2, 0.3 & 0.5. Plus a new hose, moisture trap & quick release valve - all for £21 Inc postage :smiling3:

I can spray a 0.5mm line, but it is difficult to maintain, you have to be very precise indeed :smiling3: with a 0.3mm nozzle. Demarcations of around 1mm are certainly doable. I do use a higher pressure and, yes, I still use those despised enamels! I've never tried to do it with acrylics as I spent most of my time trying to unblock the airbrush, cleaning the nozzle tip etc. I'm sure there are many more competent than me who can do it though.

I can achieve a 0.5mm line relatively easily with my Iwata Hi Line HP CH. I use acrylics, and all I do is set the pressure to 25-30psi, set the needle stopper to the lowest setting, and .5 lines are relatively easy to achieve.


Cheers, John

Two questions 


1 how do I set the PSI ? 


2 what's a needle stopper ?


i only have a cheep compressor so 1 might not be possible

1.


that's the pressure Gauge. If your compressor does not have it, I think you can buy one relatively easily on ebay


2.


Search up Iwata Hi LIne HP CH and look on the end. There is a little knob that when turned, limits how far back or forward the needle goes. Alternatively, it can be set all the way back, and you have full control over the needle

I do have a pressure gage on mine but it's just a clock with a needle , my compressors has a switch I can set to either full or two thirds , if I have it on full it will switch off once the tank is full , if I have it on two thirds it switches off at 40 psi 


I know what you mean now my brush has the regulator in the same place 


cheers John
