How to Make a Paintball Bazooka

While paintball is a sport/activity of skill and marksmanship, it can always be made easier by the invention of better technology. Sometimes that technology involves shooting a larger quantity of paint or balls at an intended target. This is where a paint bazooka comes in. And they are not difficult to make as long as you have the right products.

Things You'll Need

• 2-by-15-inch PVC pipe
• 2-by-2-inch PVC pipe
• 2-inch PVC T fitting
• 2-inch PVC cap
• 2-inch PVC reducing bushing
• 1/4-inch short nipple
• 1/4-inch steel 90-degree elbow
• 1/4-by-5-inch steel nipple
• 1/4-inch ball valve
• 2 reducer bushings (1/4-inch to 1/2-inch and 1/2 inch to 1/8 inch)
• PVC cleaner and cement
• Teflon tape
• CO2 ASA valve (bottom-line style)
• CO2 paintball gun tank
• Clean rag

Instructions

Building the PVC Section

1. Wipe off the end of the 2-by-15-inch PVC pipe with a clean rag. This will eliminate the debris from the end and allow a cleaner seal with the PVC T fitting.

2. Brush the PVC cleaner and cement onto the end of the PVC pipe that you will be placing inside the T fitting. Cover 1/2 inch of the PVC pipe from the edge inward, encircling the entire pipe with the cement.

3. Place the T fitting on the end of the pipe that you have just covered in PVC cement. Do this step before the adhesive dries.

4. Place the 2-by-2-inch PVC pipe into the opposite end of the T fitting. Cement it in place properly as well. If done correctly, it should look as if the PVC pipe has gone completely through the T fitting and come out the other end -- with the bottom leg of the fitting still open.

5. Cement and adhere the PVC cap to the end of the 2-by-2-inch PVC pipe. Make sure to leave the 15-inch PVC pipe open and clear.

6. Cement and adhere the 2-inch PVC reducing bushing onto the bottom, open end of the T-fitting. This will shorten the opening of the PVC pipe to an opening of 1/4 inch.

Starting the Steel Section

1. Wrap the threads of both ends of the 1/4-inch short steep nipple with Teflon tape. This will seal connections when screwing them into the elbow and the bushing from Step 6 in Section 1.

2. Screw the nipple into the end of the PVC bushing. Making sure that the connection is secure and airtight. This will ensure that the compressed air will not leak out at inopportune points.

3. Screw the 1/4-inch 90-degree steel elbow onto the open end of the nipple. Use a wrench if necessary to make the seal as tight as possible. As for position, try to get the opening of the elbow to point in the same direction as the opening of the 15-inch PVC pipe. This will make control and operation of the device easier for the user.

4. Wrap the threads of both ends of the 1/4-by-5-inch steel nipple with Teflon tape. This, again, will seal connections when screwing it into the elbow and valve.

5. Screw the 5-inch steel nipple into the elbow joint that you assembled in section 2, step 3. Use a wrench if necessary to make sure the seal is as tight as possible--again, not wanting to let air leak out.

6. Screw the 1/4-inch ball valve onto the end of the 5-inch steel nipple. Make sure the connection is secure. Test out the valve release lever to ensure that it is a fluid motion. If not, lubricate the valve with WD-40 to make the action more fluid.

Connecting the ASA CO2 Assembly

1. Wrap the threaded ends of both of the steel reducer bushings with Teflon tape, ensuring a tight seal.

2. Place the 1/4-to-1/2-inch reducer bushing into the open end of the ball valve. Screw it in tightly, using a wrench if necessary.

3. Place the 1/2-to-1/8-inch reducer bushing into the 1/2-inch open end of the bushing in step 2 above. This will allow a 1/8-inch opening in which to connect the ASA CO2 assembly, through which the pressurized gas will flow through.

4. Screw in the ASA CO2 assembly into the 1/8-inch open end of the bushing from step 3. This is the completed assembly of your paintball bazooka, minus the CO2 tank.

5. Make sure that the ball valve is closed. If you have it open while you insert the paintball gun tank into the ASA assembly, you will loose a massive amount of air pressure.

6. Finally, screw in the CO2 tank into the ASA assembly, completing the device. To fire it, simply turn the ball valve open, which will release the contents of the gun-tank, propelling the balls forward.

Tips & Warnings

• This device will not shoot a great number of volleys because of the large amount of air that is released with each opening and closing of the valve. Therefore, make sure that you have spare tanks ready at hand.
