Yes its been done a million times before, so i thought id give it a try. And boy am i glad i did! This baby is powerful, durable and good looking.

Materials:
1- 3/4' ball valve
1- 1 meter of 1/2' PVC
1- 1 meter of 3/4' PVC
1- 1 meter of 1' PVC
2- 1' PVC end caps
1- 1' PVC 90 degree elbow joint
1- 3/4' PVC end cap
1- 1/2' to 3/4' PVC connector
1- 3/4' to 1' PVC connector
1- 3/4' PVC 'T' joint
1- 1' PVC 'T' joint
1- bottle of PVC primer
1- bottle of PVC cement
1- tubeless tire valve
1- sports pump.
1- Piece of small steel piping

Method:
I new i wanted to make a homemade, so i looked up the directory and they were all good but none of them caught my eye. So i sat down and said "Ah screw it ill start from scratch"

First i wrote down everything i needed and went to my local plumbing store, and bought everything. $24 later i came home and started cutting the PVC to the size i wanted. I pieced it all together and didn't like the look. I tried a different way and loved it.

I put the primer on the inside and on top of the pieces i was joining then applied the PVC cement, and waited over night.

I was dreaming about it all night, just praying it would work. Finally i woke up and picked it up, put a dart in and ... FAIL. It had so much air but the dart wasn't shooting so i searched around and came across some small steel tubing and put it in the barrel, along with the dart. I pumped and pumped and pumped some more, went out into my street and fired. I got the streamline 100ft.

Clean up the spelling and capitalization. Run your posts through Word if you need to.

Ok sorry, thanks for the heads up. Other than that, good or bad?

So where's that picture of the good looking gun? I only saw a blurry shot of some random glued together pieces of pvc with a pump dangling on the end...

Sorry, but your gun is not looking nice, or good, THIS is a good looking homemade....

Ok it might be powerfull, pro's for that, but it seems like you have to "fire" the dart by opening the ball valve, in no way you can open that fast enough for the dart to fire, unless you use a tight fit barrel, wich you did.
And with tight fitting darts in a air pressure gun, you lose ranges, so the dart could fire even further with a quicker pressure release valve.

[GreenyNerf96]

Well how do i make a good one with a fast release trigger? Ive looked everywhere, and cant find 1. And even if i did none of them make sense to me! And i think its good looking. In my opinion the one you showed me was also bits of PVC thrown together but it had a paint job. Yeah the triggers better, but how is he getting the air to fie a bullet? Ill be painting mine soon. Yes, his is better, but i made mine the way i wanted it, without any knowledge of homemade guns.

Maybe you could make some kind of arm on the ball valve with a rubberband to "accelerate" the opening time....

But I believe there are many types of valves, maybe there are butterfly valves that open quicker?

In the mythbusters chickencannon there was an butterfly valve.....

[DTReaper]

Instead of rubber bands you could try to make the ball valve spring opened. Basically you need a strong extension spring and a catch of some form and the opening time will be cut down significantly thus making it go further. I believe spudfiles has a few guns with a system like this. Hope it helps.

Or just ditch the ball valve for a Sprinkler valve, or mod a check valve in to a dump valve.
