The potato may not be the ultimate projectile, but they can still go pretty fast, at least for the first few metres.

But there's quite enough pessimism around my life from others as it is at the moment, so I'll smile brightly and wander on.

....Then i would be unable to unscrew the barrels from the QEV, anyway, the barrels are light enough to not bend towards the end of the pipe.

You know what, it would be nice if someone made a how to on a piston valve for copper pneumatic cannons. At least i dont think there are. Is it harder to make a copper piston valve? An also what are compression fittings and how do you install them ( couldnt find anything about it in the wiki) and do you use copper epoxy the same way as plumbers epoxy?
