G'day guys,

My father got me a ball valve. I know its not a QEV valve but i'll still use it and see what I can make.

The ball valve performance will become boring. Springload it or actuate it with a ram or servo for better performance ...

G'day guys,

My father got me a ball valve. I know its not a QEV valve but i'll still use it and see what I can make.

Cheers!

OK, so would a QEV best suit me? I just need to make sure.

What could I use as a trigger? The fire extinguisher?

Ok guys, I've decided to make a single shot gun.

So a QEV valve would best suit me right?

Sorry if I've got questions going left, right and centre but we all have to start somewhere...

Also, which type of fire extinguisher do yours reccomend I should get? I'm also a voulnteer CFA fire fighter so ...

I'm from the land down under (Australia) by the way fellas.

All I need to know is which valve would best suit me! I don't care if it's tricky to mod or anhthing, I can do it!

Is that how a QEV valve works? To see a better picture, click on it.


If so they look to be a a lil bit simple. I'm get a rough idea of how some valves work now! Just needa pick the right one for my needs!

People seem to have problems with google and searching..

Ball valves are simple to use and cheap, but mostly you'll only get one shot (unless it's full auto/strafe). The problem with them is that the projectile has pretty much left the barrel before it's fully opened. You can use springs/elastic ...

hmmm valves = bit confusing for me!

I've got a rough idea of how it's all going to look but I don't know which valve would be best for me. As I say, I want to use maxium pressure. As soon as I hit that trigger, I want that ammo gone in a flick!

Would a BBMG be easier to make than a single shot BB ...

Be aware that it will take you a while to pump it up manually, but let's say you get to 150 psi, that will give you a good amount of air for a BBMG. You can keep the original trigger on the fire extinguisher and fit a barrel and cloud chamber.

I made a very improvised variation of the idea here ...

I'm a bit confused on all this, but what I am wanting to make is a gun with a longish barrel, ammo will be 3-6mm ball bearings, I want it to be quite powerful and I'm looking at using a fire extinguisher or something as an air chamber thing.

That's not very detailed in terms of specifications ...

Also, would a fire extinguisher (small one 1-4kg i'll probably buy) hold a large volume of air? I want my gun to be quite powerful rember.

is there anything on the net that explains the difference between types of valves??

Also, which type of valves are the best? I'm after one that doesn't loose much power.

I'm looking at making my gun similar to these:

G'day guys,

I'm looking at making a pneumatic gun.

Cheers for the replies!

Just a quick question.

Because I am going to be using a sprinkler valve, which sprinkler valves are the go and why and which ones should I steer clear of and why?

The thing to do now is incorparate your own knowlage/skills into the designs that you have studied.

Suggestion, draw your idea on paper and upload it, do it in MSpaint or other program of the like. Run it by us and get ready for the reply opinions/suggestions/likes/dislikes of your design.

That ...
