You forgot about being able to take a piston valve (for the most part) to a higher pressure, thus making for a more powerful shot, if that's what is desired.
Yeah, thats my main reason for wanting to do a piston next.

Are pistons that much more effecient? It seems to me like a sprinkler valve is very similar to a piston as it is. At least thats the idea I got from opening the sprinkler valve when I put the blow gun in.

basic copper pnuematic pnuematic

So here is my first pneumatic. went for copper with a modded sprinkler valve. This was done mainly for practice. The chamber is 25 inches by 1 inch. the barrel is 48 inch by .5 inch. The valve is a modded 3/4 orbit sprinkler valve. I have taken it to 140 psi with a shock pump I have, but normally us...

he said he shot across his 10 acre property. my dads 10 acre property (its square) is 660 feet across, so about 220 yards, or right around 200 meters. so if the property he is shooting across is square, he is shooting around 200 meters.

I will go ahead and disagree with the majority here... the lantern sparker has worked great on my last combution. go ahead and use it. just make sure that it is easy to get to when you need to change the flint. and as others have said, put a computer fan in the chamber, it really does make a huge di...

right on.. Until I read your response, I didnt see much of an issue with the whole subject. But your explanation makes sense. And while on the subject, does anybody know the actual laws on using a spudgun for hunting? I havn't built one capable of even trying, but I am curious. And if I do build one...

the ugly sexiness

Hey all... my first cannon. first post too. I built this about 2 years ago after remembering a cannon that my friends dad had. It was around ten years ago, but I remembered the basics of how it was put together so I decided to build one. It has a 2 foot by 4 inch chamber and 4 foot by 2 inch barrel....
