Hey all. in my recent foray into painting, more specifically priming and sealing, i have made a few notes and have a few queries...... I have attached a pic of my gun. it's of Taiwanese decent.
while shooting, i used the plastic back drop to adjust and tune the spray on, it was really enlightening as to what affected what, as far as adjusting this knob, or that knob, etc. etc.......
so my main concern is how to best adjust it. i noticed that i got what seemed like excessive over spray, ie; when i got through, there was a fine 'dusting' covering the surfaces of the truck. maybe i didn't have enough air OUT? as in ventilation..... or is the air pressure to high at the tip? i'm running 80 psi off of the tank, into a coil hose to a h2o separator,into a pvc pipe app. 35' to a 25' hose to a disposable drier to the regulator on the gun, set @ 50 psi. the chrome screw set at the base of the gun,(left of the air inlet) that is air pressure control right? i can crank it down, and it helps, but you get to a point of diminishing return, where then it begins to 'splatter' the paint, ie; not a fine mist. i've tried turning the paint flow knob down in conjunction with cutting back on the air , and just don't get the results i think i should be getting......
i'm running the paint needle (a 1.3) 1 1/4 to 1 3/4 turns out, i seem to be getting good paint coverage with that, any more and i get big particles instead of the mist. ......
maybe i just need to play with it some more.
how do you determine psi at the tip?
any ideas or suggestions?
