Now with this busted ass gun I decided that if it was broken like this I should make it better and I came up with a pnuematically actuated piston valve. I have several drawings here is a hand drawn one with no markings
and here is one made in paint with markings
Now if you have any particular questions about these just ask and I will try to answer them. Also as a side note for the drawings the neoprene washers most likely can be replaced by several o-rings. Now I have most of the parts I need for this gun but I still need a few last parts before I can finish these include a schrader valve and 2, 1 and 1/4 inch neoprene washers (if I decide to go that way). Also I could change the ballvalve in the valve for one of those blowgun things. Here is a picture of all the parts I currently have
I hope to start this project fairly soon but I don't know when I can but I will try to update from time to time.
But for now and questions comments or suggestions

That's it. I'm done. I'm sorry there are breasts on the Internet.

Well a blowgun is just the thing that people use in shops to focus pressurized air but the reason I want to use one is because it instantaniously opens and can exhaust the air behind the valve far faster than a ballvalve. So really it is the same thing just a little better than a ball valve. It pretty self explanitory but here is a picture of a blowgun http://www.homedepot...uctId=100073836 . So any more questions feel free to ask.What do you mean by blowgun valve? Check Valve?

Also Bash time what are you think putting 140 psi in that gun after you drop it. Dont you know when you drop pvc its structualy integrety is compromised. Making prone to just blow apart, and you where very lucky with that other one. Know why, I will tell you pvc tends to frag when it blows (as in blow into many smaller peices with sharp edges).
So for your own safety please read up more on what you are doing.
http://www.spudfiles...title=Main_Page Link just for you
Also that piston is poorly designed. Over on spudfiles they have lots of piston valve designs and other stuff to, just dont post that gun unless you want every one to mega time bash you.

and here is the redesigned piston next to the old one.
as you can see I also decided to add a spring behiend the piston to make it more efficent so it automatically resteats itself once all the air in the primary tank is gone. It also means I don't need as much air behiend in the piston tank.
And here it is all together
All together I am extremely happy with the gun. It exhausts all the air in the primary tank really fast. A ball valve takes far longer to open then this valve. So this increases the initial velocity of the gun by leaps and bounds because it needs less barrel length to get the best air speed.
So questions comments critisism (besides the aformentioned issues)?

edit: the ranges are spectacular, it has about a 12 inch barrel and it is getting over 100 feet flat with mega stephans. Also the ranges for angled are about 250 feet at least. once I get the right size barrel for this gun it will be hitting better ranges these are just the preliminary ranges.
