Airbrush troubles
Posted by el_jere on Sunday, August 21, 2005 10:18 AM

kg/cm2 multplied by 14.230 = pounds per square inch (psi)
psi divided by 14.230 = kg/cm2

depending on what kind of airbrush you have 284 Kg/cm2 would be a good starting point to try your pressure out according to Scott's formula... a little less if you are using a gravity fed, say around 215 Kg/cm2 or so... then adjust it till it sprays like you like it (covers the plastic but doesnt spatter or dry before hitting the plastic) and that is about the number you want for airbrushing..

Uh, I think that's a little bit on the high side .... 284 x 14.230 = 4,041 psi
I think you meant 1.40 kg/cm2 although even that is higher than what I usually use.

1kg/cm = 14.22psi, 2kg/cm = 28.44psi thats pretty well much the range you want to use it in, you may want to ditch that gauge and get something in psi, with plenty of graduations in the lower range, it'll be easier to set that way
