I found this site via google images & was impressed with all the ideas and workmanship! Feeling inspired now. :-).
I paint murals outside a lot and jump between using spray paint and then airbrushes for the fine detail (both water and spirit based paints).
I'm thinking of ways to make an airbrush type devices or modify an existing airbrush to fit on to a spray paint can in order to have more control over the paint flow for finer detail, like with an airbrush. (I'M NOT LOOKING TO DECANT PAINT FROM THE CAN & PUT THROUGH THE AIRBRUSH.) As I do this already - I'm just thinking of ways to eliminate the traditional airbrush outdoors.
As anyone that uses spray paint a lot will know - the pressure in a spray paint can (which is unlike an airbrush in the sense it has has both the pressure/propellant & paint combined) is quite powerful. Which in turn can make fine detail quite hard and tends to come out quite splattery in comparison to the airbrush.
I have some ideas of modifying parts of an airbrush to fit a spray can but I was wondering if anyone had any ideas?
Although I want to use the pressure/propellant from the can to atomise the paint I imagine I would probably need something to reduce the pressure before it reaches the airbrush part to control the paint flow. Maybe a small side chamber that the contents come out from the can into and is then controlled by an adjustable airbrush(mac) valve before it goes into the airbrush part that atomises the paint in a gentler & finer spray.
Or maybe there is someway I can separate the pressure/propellant from the paint then reduce the pressure element.
Although I decant & put spraycan paint through the airbrush I'm not 100% sure the airbrush type needle & nozzle will will work on the model I have in mind.
I've seen people have already made their own airbrushes on here so any thoughts or suggestion would be much appreciated.
