Airbrushing fine Acrylic lines?

Mike,

Try upping your thinner to paint ratio, say 75:25 thinner to paint, turn up your pressure to about 31-32lbs, and barely open your needle. When you paint, get the brush very close to your work surface, say 1/4 to 1/2 inch. The thinner to paint ratio also depends on what color you'll be painting. Generally you need more thinner for darker colors and less for brighter ones. Practice on some cardstock for a while and you should be able to get some good results. I just took a class on airbrushing a couple of weeks ago and was amazed at the results I can now get with my trusty old Paasche H. You should be able to get almost a pencil-like line with the VL. The best thing to do is practice, and play with different pressure settings, and different thinner:paint ratios until you get what you're looking for.

Good luck,

Jeff

Mike, like jeff siad, it's a question of experimentation and practice.

I've been working on the fine line thing for the squiggle camo on my do217. It would look fine in 1/48, unfortunately the Do217 is 1/72.

Just got to keep practicing.

Lots of people say you should increase thinner to the apint and then drop the pressure but I find it eaasier to have a higher PSI and just open the nozzle up very slightly keeping it close to the suface of the model

To each their own method. When I do fine lines I thin the paint about 1:1 and drop the pressure to the point that my gauge barely registers (probably somewhere around 7 or 8 psi).
