THis has all definitely helped but we'll have to hit up the home depot tomorrow and get some elbows and maybe tees to make this think worthy if at all. Thing that is killin gme is that I have the delicious flavor of regged co2 and i can't harness the power!

Its going to be too hard to keep this in the shape of a gun with all the regulator and ball valve setup I think.

I am not so sure that a schrader would pilot it enough. My pilot volume is too large right now I think. I think what I might do is try to go the spring loaded QEV route and see if I could just bypass all this shit and put a spring behind the QEV diaphragm and see what happens. I just want this to be...

I thought about the full auto for a while with the pop-off but I think that's overkill for what I am wanting to do. Eventually this gun will shoot 1/4" steel slingshot ammo. And I searched for a spring loaded ball valve and could not find it? Any help on that?

I think what I'm going for is too much of a semi/auto deal here. I want it to fire as fast as I can pull the trigger really and I just don;t think it's possible with this setup. I might just keep it simple and open the valve to fill the chamber then close it then fire then reload and do the same thi...

But a ball valve would have to be manually actuated and then re-closed? How is that semi-auto? See with the blowgun I can push it and then immediately release it and the pressure goes back up. I think I'm just confused and need a visual aid from one of you guys if your willing. I want semi-auto like...

Wait... I'm sorry I don't get this but what ball valve and where located on the cannon. Does this solve my semi-auto problem? Right now as shown in the video I regulate the co2 to 500 then open a 3/8" ball valve into the chamber, then I close the ball valve and pilot the cannon. It works good for th...

Sorry for the triple post but I will try spring loading the qev.... I have to machine an epoxy part on the lathe so that I can go from the 3/8" threads to the barrel. Some sort of tapered rig,

so it does work properly... what was the problem with it ? I find it hard to restrain from suggesting switching to a DCV :D it might seem as a more complicated route as you can't get these things in a hardware shop but at least you could get something that is much stronger than a blowgun so the two...

I have access to a lot f tools in my garage so I will be putting a nice wooden stock on here. I am just trying to figure out how to make it semi auto. Just got done pressure testing it at 500 psi with 0 leaks so I think once I get the barrel It will be ready to go. I might have to reconfigure the pi...
