A we've?

I'm uploading another video to youtube now of a better shot.

Yeah I have a spare one that I'll screw on next time I use it. Hopefully I'll be able to order a new valve soon too

Very nice gun you got there! I'd love to see some damage videos

So I'm in the process of making the coolest pneumatic weapon of mass destruction ever seen, but I need to get some o-rings. Home-depot only had tiny ones. I'm looking to put it on the outside of a 1.25 in. coupler to make a piston for a 2 in. piston valve. Also, I need some that seal well on the out...

You guessed it! I was shooting water to clean out the barrel. Well your idea worked really well for 3 shots! lol. I'm kinda disappointed, it took me forever to get the thing actually all fixed up, but it happens I guess.

And yeah, I figured buying a new one was cheaper, I just didn't know for sure

I was just shooting one of my launchers that uses a modified rainbird valve and my trigger valve snapped out of the rainbird. Does anyone know where/if there are replacement parts for rainbirds? The body of the valve is okay, just the top that gets screwed in is completely obliterated

alright, ill give it a try!

yeah i'm using a sprinkler but for some reason it doesnt seem like it's opeing all the way. If i can get this darn video uploaded, maybe you could see. It almost whistles for a second or two before firing

There i posted the video

This is my first piston valve gun. It has two 5 ft long air tanks, 3 in. diameter. The piston housing is 3 in. with a 2 in. barrel. Soon to come: golf ball barrel! I'll see if I can get some videos later. The only issue I have with it is that sometimes my pilot release valve doesn't bring the piston...

If you searched for good deals, you could probably find a solenoid online for under $20. those are easy to modify (hundreds of videos on youtube as well as posts here). Also, golfballs fit perfectly in 1.5 in. sdr-21 or at least so i've heard. only probably, here in new england, i haven't had too mu...

If I were you, I would start off with a ball valve launcher. Real simple, maybe a 2 or 3 inch pvc air tank 2 ft long or so, and any barrel of your choice (just make sure it's the same size or smaller than the valve you use) My first pneumatic was a ball valve launcher, and i was able to send an arro...

I know what you mean. If you ever do get around to it, I'd love to see how it works!

I'm not feeling to confident in this idea for my gun. I'm sure it'd be much more practical with other builds that use higher pressure. I still think a blow-forward bolt would probably be my best bet.

Well now that it's 2012, chances are you don't really need anymore input, but during my aimless wanderings on spudfiles, I saw this and couldn't resist commenting... I've actually thought up a similar design before and faced the same swivel issue. why not make the entire gun swivel? In my plans (whi...

Much less meaning sub-100? Like 80 or 90?
