I know I just posted something recently but I did a search on air tanks and all i got was different things people have used for a tank. My question is that when you pump a homemade nerf gun where does the air go? It can't go straight to the ball valve. I'm sorry for the question but all this techincal talk confuses me. So could someone break in down into english so i can learn how to build homemades?

You're pumping into a holding tank (bladder) which, after having been pressurized to an effective level is released by a trigger valve to fire the dart.
Obviously your pump will need a one-way valve so that your pumping action only adds air to the tank.

It goes into a tank that holds the air pressure. You use a pump that takes in air from the outside world, and pushes it into a peice of pipe. That peice of pipe is called the pressure chamber. The more air you have, the more it pushes against the sides of the pipe. That means when there is an opening (ball valve), the air is able to break free and rush out the valve.

Edit: you beat me

You're pumping into a holding tank (bladder)

There are VERY FEW homemades that use a bladder. Most just use a solid tank.

Everything before the ball valve is considered to be the air tank. If you take a look at the Zero's generic ball valve homemade, you can see what I'm talking about:

That "U" shape, along with the handle that connects both the top and bottom, before the valve is where the air pressure is held. Once the valve is turned, all the air pushes out of the barrel. Its really that simple. Same thing goes with other large airtanks that people use for their homemades; all space behind the valve is where your air is held.
