How to make a homemade airbrush

Painting with airbrush is fun and very efficient, as creations can be made more quickly with this device than with brushes or other techniques. It is also extremely precise and allows even high quality portraits to be made. Next, we will look at a technique for making a homemade airbrushusing simple materials and the basic principles of air pressure.

- A rubber hose.

- An empty (plastic) ink bottle with lid.

- Silicone.

- Insulating tape.

- Ink.

- Water.

Creating our homemade airbrush

To start creating our homemade airbrushFirst remove the ink tube from the pen or pencil, taking care not to break it.

Once the ink tube has been removed, we join the open mouth of the pen tube with a small piece of rubber hose, which we will fix with insulating tape, taking care that there are no air leaks between the tube and the hose.

Now, we make a bend in the pen tube. Being very careful not to break it, we place it at a 90-degree angle, so that it forms a kind of letter L and is very firm.

Then, using a drill or a punch, we make a hole in the lid of the ink bottle, with a diameter such that the pen tube can pass through this hole without any inconvenience.

Next, we insert the tube through the hole in the lid and place the angle on the surface of the lid, so that it looks like the tip of a commercial airbrush. With the silicone, we seal any possible air leaks at the top and bottom of the lid and fix the pen tube to the lid.

Now, just dilute a little ink with water inside the ink bottle and cover the bottle with our airbrush, we make a slight pressure on the bottle and we will see how the ink spreads on the sheet as a airbrush commercial.

How it works

The pressure exerted on the bottle pushes the ink through the hose and then through the pen tube. The ink reaches the tip of the pen and is diffused, as in a commercial ink gun. This is how our homemade airbrush.

    I agree with the previous comment that show step by step, how to make the airbrush, and everyone is interested in what is useful and practical for their needs.

  2. I don't mean to be rude, but I really doubt anyone will understand this tutorial. I hope you can come up with another one on the same topic, but that really shows the process clearly, thank you.
