I was wondering if someone could suggest a good way to build a cannon that comes apart into a couple pieces for easy transport. With the PVC cement this is impossible and it makes moving the cannon around kinda hard and its no easy to store either. So I was wondering if there was a way to make it into two pieces, like say the barrel and the chamber. Could I use threaded pipe for this, or would that not hold well? Any help would be great.
good luck

Welcome to the forums! Threaded pipe will work fine, in fact many people have detacheable barrels/chambers. PVC fittings come threaded too. Check out for some example.

Scroll down to the bottom of the page: The barrel and combustion chamber have Male and Female adapters on them, making them removable from each other. ;)

They don't sell threaded sch 40 PVC because it makes the walls too thin/weak. As suggested, the threaded fittings are the way to go.

A solid bonus of a detachable barrel is that it allows you to use a single chamber with several barrels through the use of bushings. With this, you can shoot paintballs, golfballs, tennis balls, spuds, eggs, and whatever else you like from the same launcher by changing barrels. Just make the chamber's threaded fitting as big as your biggest desired barrel, then use bushings to adapt down to the smaller sizes. The chamber is where you spend almost all the money on a spudgun anyway, with larger pipe/ignitor/fan/metering/etc.
