lethal much? looks sweet.

I see only one chamber and one moded sprinkler valve for dumping air, thier is only one shot unless you have a second tank with a valve to refill the chamber between shots, or a regulated air source (CO2 or compressor tank)

also what did I say about a barrel sleeve

The second design is made so ...

Well if I added a CO2 tank it would do the same thing...

New Design:



Thoughts?

why do you need a loading system? you would still need to pump it up each time, unless you used CO2

You don't release all the air at one time... so no, you don't keep re-pumping. You can probably get 1-3 shots off of one tank, and yeah.. I could switch to C02 and put a PSI Burst regulator on it ...

It took me a few minutes to understand because this design is so unconventional. The direction of feeding (top or bottom) isn’t a problem at all; this thing has got to be single shot,
I see you are closing the chamber using the bolt to slide over the opening, save your self the trouble and create ...

i see what you mean
like a springfield rifle they used in wwi. Your better off trying to use a bottom loading cartrigde/magazine with a spring and bolt though, like modern weapons, so that another round doesnt fall in as you are shooting, but that design would also work you just might get ...

I don’t understand what you want

Its not like you can go to home depot or some place and say “hey do you got any cartridge loading systems for pvc, “yeah there’s one right here for loading AAs into your plumbing”

If you have to think up this stuff up to fit your gun, we don’t give or, tell pre ...

I'm not familiar with all the terms yet... so... what is bolt and what is breach?

Are there any cartridge loading systems available? I'm using AA batteries for ammunition. I'm currently trying to design one right now and I have a pretty good idea of what I'm doing... at this point I'm just trying to make it look good.

Chances are that I will be shooting 1/4" or 1/2" marbles out of a 3/4" ID x 2' barrel @ around 120-125 PSI.

#1 where are you getting a compressor that goes up to 200?

#2 Few people sell them that are rated to that high. You're better off making your own out of sch 80 pipe and sch 80 fittings.

Well, I've yet to look for a compressor that goes that high...I was kinda assuming that home depot would have ...

They are rated to 120psi, so I wouldnt go over that.

A sprinkler valve is a basic diaphram valve. When you pressurize your chamber, air bleeds through an opening in the diaphram, into the "cavity" in which your blow gun is mounted. A much larger surface area is exposed on this side of the diaphram ...

I'm not too sure how the modified sprinkler valves actually work. So if someone could also shed some light on that as well... but my question is: what is the max PSI a modified sprinkler valve can handle before it just 'goes off'?

I am pretty new to this area. I have built a PVC Pneumatic marble gun in the past(quite recently).

I want to get a trigger... what should I use?
What does 'Stock' mean?
Why would I use a modified sprinkler valve?
Is there a post/site that provides basic parts required?

Thanks
