                        I have been bought a small silent compressor (easy to work in the same room!!) and a Paasche VL Double Action brush. I will be taking lots of practice to get used to the double action prior to attacking any model in anger. But I was wondering what sort of pressure I should be using through the brush? The compressor cuts off at 60psi, and cuts in at 40psi. But many of the posts in here refer to pressures down round 10 psi!! I only acheived that pressure with a leak!!! Sad [:(]

                        I use Tamiya acrylics - perhaps a hangover from brushing, but they are readily available over here, and I have an extensive range still to get through.

                        Your assistance will be appreciated Smile [:)]

                        I also use a Paasche VL but use mine at around 10-20 psi.

                        It sprays Tamiya acrylics well, once thinned. If you can get your hands on some Gunze acrylics, I'd recommend them over Tamiya any day of the week. They spray on so much smoother and are so much easier to work with. They are available at Hobbyco in Sydney.

                        You should be able to get a air regulator from somewhere that will dump some of that excess pressure and give you around 20psi. The only way you will get lower pressure is to have a leak somewhere.

                        hope this helps.

                        I don't know what will be necessary to get your compressor to a lower pressure, more than likely just a regulator, but that is far too much pressure for airbrushing models. You can do general coverage, but at those pressures there will be so much overspray you'll be blowing paint everywhere. You may also have a problem with "Orange Peel" or a very rough finish.

                        Taimya acrylics airbrush very well, I use them a lot. I haven't tried the Gunze line that pingtang mentions, however I have heard very good things about them. I also use Testors Model Master acrylics and Poly Scale.

                        Sounds to me as though you have the unit with the holding tank underneath the motor unit, if so it should have a dial and a guage, on the watertrap for adjusting the air pressure, if so set it at 20 psi without depressing the trigger, it will drop down to around 15 psi when the trigger is depressed.

                        I taught airbrushing to beginers, using the Passche VL and acrylic paint [only for ease of cleaning], using a Sparmax Compressor that was set at 15 psi.

                        Lobbie,

                        Thanks for the guidance. There is indeed a valve on the bottom of the water trap - a perfect option for bleeding off excess pressure - at least to start with.

                        Of course the only down side is that the compressor is constantly running, so a regulator may still be the go in the long term.

                        Many thanks all Smile [:)]
