wisdomknight Posted June 6, 2016 Share Posted June 6, 2016 I have a compressor that I can connect two airbrushes to via 2 different gauges. I was thinking that since airbrushing fine details usually need a PSI of around 20 but its so much easier to shoot cleaner through the airbrush using a really high PSI. What if you connect 2 hoses to 2 diff gauges at 2 different PSIs both with quick connects. Anyone do this? Is this viable? 1 Quote Link to comment Share on other sites More sharing options...

I have not specifically tried it, but I had started to build my own manifold to allow me to do this.... So I believe it should be perfectly viable. After all, when cleaning you raise the psi up to blow the cleaning agent through.... What type of paint are you doing detail work at 20psi? I always find that much over 10 psi I start having issues... I use a Grex Genesis XS by the way....

wisdomknight Posted June 6, 2016 Author Share Posted June 6, 2016 (edited) Im just using the Master Series paints..Im experimenting with adding medium, water, flow improver ratios right now. Maybe I should go lower in PSIs but would that even get anything out of the airbrush? I use an Iwata HP C plus .3mm nozzle Edited June 6, 2016 by wisdomknight Quote Link to comment Share on other sites More sharing options...
knarthex Posted June 6, 2016 Share Posted June 6, 2016 (edited) The Grex is the same .3mm, I have used Tamiya paints mostly, thinned 50% or so with X-20A thinner, Scale 75 paints, thinned 50% with Scale thinner, GW thinned 50% with water and flow improver, Vallejo Model Color thinned 50% with water flow improver. It typically takes more than 1 coat.... The only MSP that I have used through my airbrush is Grey Liner, See Here for my Wip with it, (9th post). I typically spray at about 10 psi with all of those different mixes, and have never had any problems. try it on some scraps or sprue to see how it works through the Iawata....

wisdomknight Posted June 6, 2016 Author Share Posted June 6, 2016 Thanks George, I will definitely try man. :) Quote Link to comment Share on other sites More sharing options...
djizomdjinn Posted June 7, 2016 Share Posted June 7, 2016 Should be doable in theory. Manifold, two regulators, two QCs. Is your regulator difficult to adjust though? I find that reaching down (my compressor is on the floor) and twisting the knob open is far easier (one-handed, just a turn of a knob) than trying to mess with quick connects in a pressurized system (they shoot off, reconnecting is air spraying everywhere against the plug you're trying to push in, etc) or turning off the compressor, either shutting off the regulator or dumping the air, doing the connect in an unpressurized line, and then repressurizing it. Also yes, how are you spraying at 20 psi? Is that measured static or while you're spraying? 20 psi seems like it'd blow the minis all over the place. 1 Quote Link to comment Share on other sites More sharing options...
