air pressure

[moose]

Well I was down stairs blowing some paint and decided to try the paper towel for a different surface. I raised my pressure from 35 to 50. What a differencce. I had less problem with dry tip. now I need to work on control at the higher pressure. Just thought I would share so other newbies won't be afraid to crank up the pressure.....

That may be what I need but paint goes everwhere when I do raise the pressure. Keep dropping hints at what helps.

i use a LOT of pressure compared to most, 75psi or there abouts for textiles. i find there's a big relationship between the pressure you run and how you need to mix the paint.....higher pressure seems to let me mix the paint a bit thicker, so i get better coverage especially black outlining on a t-shirt.

Interesting. Lots to learn about pressure, as I increase my regulator pressure it does get easier on all fronts. Its like HVLP guns, we use 65-90 into the line, and 19 lbs at the gun. Still trying to learn the dynamic of that.

If you are doing very fine lines with a good airbrush, you might have 50 or more lbs at the regulator, but only letting 6-18 lbs out at the trigger. That I think (someone correct me please) is where you gain control of exact pressure at the needle. I have a Micron with the air valve and you can literally shut off the pressure there. When I have 50 at the regulator, I put the air valve about half way open and I can draw pencil lines till the cows come home, with nearly full trigger control, which makes starting and stopping very easy.:skull:

blinddog you may have solved one of my quandries ...i shall crank up the pressure till the last 3 remaining hairs on my hair are blowing in the breeze

LOL, jc, try it, and Clem, you are right. With that kinda pressure you gotta learn a very light touch on that trigger pull back. Easy big fella..........
