Different types of airbrush, why?

[RedgateModels]

It was my birthday yesterday and I got my hands on the airbrush setup bought from ebay earlier in the year.

 

Now, there are two airbrushes in the kit. Both are dual action. One is this one:

 

Brush 1

 

this has the jars that sit under the brush, the other is like this one but the nozzle is 0.3mm and the paint reservoir is bigger:

 

Brush 2

 

First question - why the different feed types, is one better suited to a type of paint or what?

Hi, The 1st works on a syphon effect, the 2nd by gravity. You will be able to spray a lower pressures with the gravity type.

okay, understand. But I still am stuggling for a killer reason why.

 

How about this one then, all you airbrush veterans out there - what type do you use?

Hello again, Have a look at this link http://www.craigcentral.com/models/ab.asp I think it may help you, and as a one stop page, tells you pretty much everything about airbrushes.

I use the top feed only as I feel that I have more control over what I´m doing with it.

The fact that the top feed ones need lower airpressure and can be used with a thicker paint doesn´t hurt either.

I have used bottom feed ones in the past, but the issues of siphoning and bottles falling off , made me go all top-feed.

There is more need for a finer needle-nozzle assembly however, as the ones you listed only have 0.3 mm sets.

A 0.2 mm will make them more useful for model painting.

I use the 0.3 mm myself when I´m doing this:

There is my opinions on what you need. Others may have different opinions .

hmmm, I'm beginning to think that I need to swap the 0.3mm gavety fed one for a 0.2mm or at least see if i can get the smaller nozzle (or whatever)

All my weathering / spraying is done using the exact same one as in Picture one. Have had a few problems with it blocking up from timte to time but thats probably from me not cleaning it as well as I could have done.
