This instructable will show you how to create an air cannon. Most of these supplies can be found at a home depot or other hardware store. The rest can be ordered off amazon. This is a moderately hard project.
I do not take any responsibility for injuries or damages done. Read and fully understand the document before proceeding. Follow all directions carefully for best results.
What did I make?
I made a powerful air powered cannon.I had all the tools I needed at home.A Hacksaw, a ruler/measuring tape, a drill/ drill bits, scissors, pliers, and an air pump with a meter. The rest of the supplies I had to buy from home depot and amazon.com. This cannon works by storing air in a chamber and pressuring the air. Then the air is released in an instant into the barrel of the gun. A projectile is stored in the barrel and this prevents the air from escaping the barrel. The air pushes out the projectile at high speeds.
How did I make it?
I got this idea from the air soft gun I made a while ago.I wanted something larger, and more powerful. I made his gun by myself, consulting the internet for help, such as hoe to make something air tight, and how to glue PVC. The plans definitely changed as the project progressed. I figured the simpler the design, the easier and more efficient the machine would be. So, I changed the design as I went to benefit the cost and efficiency.
Where did you make it?
I made the whole cannon at home in my back yard. I don't have a work shop so I used my concrete patio for all the cutting, gluing, and assembling. This was a fun project to build, as well as use after the construction was complete.
What did you learn?
I learned that making something airtight is harder than it seems. I used epoxy and PVC cement to make sure absolutely no air escaped. Also, I learned that you always should give a sufficient amount of time for glue or other bonding materials to dry and set. If I did this project again, I would use a remote valve as a trigger instead of a ball valve. This would make the release of air faster, and therefore giving more power to the projectile.
