"Stuck Needle"
Copyright 2007 Airbrushtech.net
The best way to remove a stuck needle from an airbrush while using acrylics is wet heat. Soaking the brush in hot water will soften and "melt" the acrylics and the needle can be removed. During on site airbrushing there is usually not a source of boiling hot water around to dunk the brush in so pliers and brute strength seems to be the only way to pull them out. Pulling a Paasche needle with pliers will curve the needle or bend the small size in diameter portion of the needle if you don't pull straight out. Bending the smaller diameter portion at the joining of the larger will most likely result in a ruined needle. To keep from having to bend your needle and maybe hit someone in the eye with your elbow while pulling on a needle with pliers this is what you can do as an alternative
Remove the airbrush from the air valve assembly or the body of the airbrush from the air valve assembly. In this photo I am removing the hose from the air valve assembly.
Every once in a while you get a stubborn stuck needle in your airbrush using acrylics that seems like nothing you do will remove it. The more frustrated you get trying to take it out the more you want to scream at it. You no longer have to scream at a stuck needle.
Place the airbrush into a container that is large enough for it to lie down in. Cover the airbrush with water. By covering the airbrush with hot water and letting it sit a few minutes this may be enough to remove the needle.
You may need to get radical if the hot water is not hot enough to remove the needle with hot water from the tap. You can boil water and cover the airbrush if you are near a stove.
Another way is to place the container with the airbrush into the microwave* and nuke it on high for two to three minutes. If you are nuking several then you will need to make sure all airbrushes are covered completely with water. You may need to turn the power on high for 4 to 5 minutes.
Be careful in removing the airbrush from the water when it is hot. Pour the water out. Pick up the airbrush and slide the needle out. It works every time.
