hello guys
well..i decided to scrap my other post, and start on some questions as i have not started on painting yet
1.how to you adjust the fineness of the paint? by adjusting the nozzle or by distance from the model?
2. what PSI do u guys normally use?

A Double Action Airbrush can do the trick. The longer you pull the trigger back, the more paint comes out.




Not sure on the most suitable PSI but I use around 25-30 PSI. You need to be careful with spraying camo over 1/72 models.

well.. u mean the further u pull the trigger back...the line gets thicker along the width( not in the amount of paint)?

What do you mean by "Fineness"?

Well yes. As long as you don't hold it in the same position.

like i would like to airbrush panel lines,
compared to airbrushing a large area.
or the width of the line

Needle size... the smaller the needle the finer the line.....

then can u increase the width? in the process of painting?

for discussion sake... Paasche VL has 3 needle sizes
each has a range of widths it will spray. My Primary AB is now the IWATA HP-C it will spravy from .35mm to 3mm or so in width. (it's a double action.....depending on how much air pressure and paint)

so there is no difference if you turn the nozzle etc?
sorry ..but i am abit slow

aslo, what is the nob at the end for? it is not stated in the instruction ^

Hi Leopald,

The distance from the nozzle to the model determines how thick the line is.. closer to the model is thinner. The trigger determines how much paint comes out.. So if your moving in closer, to get a thinner line.. you don't want to be pulling back too much on the trigger.

What I usually do, is get close, with the trigger all the way forward.. then slowly pull back until the paint JUST STARTS to come out.. then keep it at that level.. If you just go in and pull to far back.. you'll noticed paint getting pushed to the outside, sorto of blowing itself away from the center. What you do is practice a few runs of thin lines on a board behind the model, before you hit the model itself...

Good Luck!!! Charlie

ahh!! ok thanks tuna!
now i would have to solve the mystery of the nob

Looks like what you are talking about is a pre-set feature. This allows you to limit the 'pull' or 'throw' of the trigger. Remember, the further you pull the trigger, the more paint comes out. The pre-set feature allows you to avoid those nasty finger spasms where you accidently pull the trigger further than intended, sending a great deal of paint throught the nozzle-not a good thing when doing detail work up-close. What you do is play around with the knob until you get precisely the amount of paint flow for your purposes, then go to work.
Hope this helps.

wow..interesting!!
