What Do You Need to Follow this Tutorial?

These are the main things that you need when making a DIY sandblaster:

Propane tank

You can make a DIY sandblaster by utilizing your old propane tank. This tank could be the one that you are using for barbecues. A small propane tank will do for this project. With a thorough process, you make a great transformation. Although, just a heads up, you need to have a welding background to carry out this task. 

The propane tank will make a great alternative for DIY sandblasters since they are built to hold compressed air. Nevertheless, you should be extra cautious since rupturing the tank can be dangerous.


Find a compressor that has an ideal PSI for your DIY sandblaster. Ideally, you can get a compressor with at least 100 PSI for efficiency. You can get one with a reduced PSI but you will have to exert more time to carry out this project. 

It is needless to say that you need to check the functionality of the compressor. As you want to make sure that it can work for your DIY sandblaster.

Step-by-Step Instructions

Here are the steps on how to make a DIY sandblaster:

1. Detach the nozzle

Take off the nozzle from an old propane tank. When doing it, you have to ensure that all vapors in the tank are consumed as it can be dangerous. Bore a hole in the top to make a filling top, then connect a lift-up top.

Bore a 1-inch hole at the bottom of the propane tank and make another 1-inch hole on the top corner of the tank. Cut 3 inches of a 1-inch male-threaded steel pipe using a power hacksaw. Perform the same step for another pipe to obtain two 3-inch threaded steel pipes. After that, proceed by joining the pipes to the sides and base of the tank.

2. Twist in the mixing valve

Get the mixing valve screwed onto the tip of the base of the pipe. Get a T-connector and screw an inch from the base of the mixing valve.

This time, get a 1-inch female 4-way cross pipe fitting and hook it up to the threaded steel pipe that is on the top corner of the propane tank. Twist in the pressure gauge that is seen on top in such a way that the safety valve is on the bottom and the pressure regulator is set to the side. Proceed by hooking up the water separator to the adjusted pressure regulator.

3. Control the incoming air

You will then have to focus on controlling the incoming air coming from the compressor going to the other end. You can do it by screwing a male threaded elbow fitting in the water separator.

Go back to the safety valve that was hooked up to the 4-way fitting and twists in a 1-inch male threaded pipe that is from the base of the safety valve. Isolate it right at the bottom of the tank, then twist in a female elbow fitting right on the end part.

Proceed by assessing the size and cut a small portion of the pipe and hook it up to the T-connector. You will have to weld the joints.

4. Connect the rubber hose 

Connect the rubber hose to the T-connector at the base, and secure the nozzle on top through a tube fitting. Because of the pressure that is present in the tank, the abrasive media mixes with the air. You will see that the media is pushed into the chamber. 

The air produced by the compressor that is entering the mixing chamber is reduced and controlled before it gets into the nozzle. By regulating the mixing valve, the abrasive can also be regulated.


There you have it! The steps in making a DIY sandblaster are quite doable. It does not require an expert hand. As long as you follow the details in the instructions, you can successfully make a DIY sandblaster. You can enjoy the use of sandblasters without having to spend much. 

This tutorial utilized the use of an old propane tank. Nevertheless, you can find other alternatives when making a DIY sandblaster. You can check the internet if you want to try other methods.
