Two Valve Air Cannon Plans

How to build this TV Two Valve Air Cannon

The TV Two Valve Air Cannon is perfect for adding that extra pressure and air flow for more distance.

Propelling projectiles with the help of more air flow will no doubt help increase your firing range to cover more of the neighborhood.

Its all fun with the TV Two Valve Air Cannon!

How to Build a 2 Valve Air Cannon

NOTE: Suggested changes that could be made in the drawing below in order to increase the air cannon power punch.

bullet The 1" (red) "T" should be a 1 1/2" "T" with a 1 1/2" X 1" adapter in each end.
bullet The 1" pipe and 1" X1 1/2" Bushing Adapter should be removed and the barrel extended all the way into the "T".
bullet The 3" X 1" bushing that the barrel passes through should be a 3" X 1 1/2" bushing.

This is my idea of and improvement to the "sprinkler valve" pneumatic cannon or spud gun.

It is my thinking that there is a "bottle neck" of air flow at the valve.

Think about this, you build an air cannon with a 3" air chamber and a 2" or 1 1/2" barrel that is fed air THROUGH a 1" valve.

Now this gun gives good performance and you may be very happy with it.

However, if you're building a pneumatic gun, no doubt it is for one specific reason, MORE POWER!

So why not use 2 valves to double the air flow, Horsepower!!!

Now this might not give you 2 times the distance but it will surely increase your range.

Fact is, the air pressure pushing the spud is not the only thing that gives it itís speed. The real factor here is the VOLUME of air pressure along with the speed at which it is being delivered that gives it its projectile horsepower.

I drew this gun up with the barrel inside the air chamber, because I am kind of fond of this design. This same idea of 2 valves can easily be adapted to the "over and under" design of the barrel over the air chamber.

The basic wiring of the batteries and triggers "shown to the right" in the diagram is a simple way to apply power.

This gun should be safe if not pressurized to more than 100 psi. even if you are tempted
to do so, do not.

100psi will give you a safety factor of 2 1/2 before the pipe will burst.

If the air chamber were to crack because of over-pressurization it would not stop there. The gun would literally EXPLODE into many very sharp pieces of shrapnel that will not only cut you and sink very deeply into your body, it might very well kill you and anyone unlucky enough to be too close to your high pressure device.

Perhaps one of the greatest features that enhance the performance of this cannon, is the dual-valve system.

Like mentioned earlier, the dual-valves allow more air flow to greatly improve the firing range.

Many more air cannon designs are offered here on our website so look around. You just may find the perfect toy to build fro propelling projectiles of your choice.
