The method believed to be used in this primitive form of airbrush art was the use of a hollow bone in which to spray the paint out of by blowing through it. While this is a very primitive method compared to modern day forms of airbrushing, it does still work. This video is offered on DVD and runs about 30 minutes. This video deals with teaching the beginner all about double action airbrushes. In spite of the fact that the video is geared towards the Paasche VL airbrush, the information taught in this video will work for any double action airbrush on the market. The air cap and head assembly are on the front of your airbrush and they cover the tip of the needle. The purpose of these parts is to control atomization of the paint spray. Should these parts become dented or damaged in anyway you should replace them immediately. Damage to the air cap and head assembly will effect the performance of your airbrush. How To Create Your Own Airbrush Art Stencils There are two forms of doing airbrush art. One way is that you can use stencils or masks to airbrush your artwork on to your project. The other way is that you can freehand the design onto your project without the use of stencils or masks. Most stencils and masks that you purchase are reusable. This refers to how the airbrush functions. With single action only the air is controlled with the trigger. The trigger will control the air and the amount of paint that comes out is determined by the needle adjustment on the back of the airbrush handle. Dual action is when the trigger on the airbrush controls both the air and paint.
