Well, I just finished my cannon, gluing and all, and now it's drying...should I wait AT LEAST 24 hours or is it safe-since there now combustions-to fire after 15 or so hours, maybe even more?

I doubt anyone here would say otherwise, it's worth the peace of mind to wait those few extra hours.
I usually fire mine after they've set overnight, but would not endorse it because then you could sue me....
I would say that the manufacturer is the best person to ask, and if I'm not mistaken it says on the of the cement can how long to wait for curing and how long to wait before testing over 180psi. BTW, an average spud gun doesn't go much over 30 or 40 psi. unless you're using some dangerous propellants.

no one could sue you, read the disclaimer on the forum! :)

I would wait 24 hours, I waited 12 hours and developed a leak, I am sure I used plenty of primer/glue, so who knows mabey it hadn't cured yet. Wait, I know it's the hardest thing to do, but you will be glad you did.

that's what we are going to "dry fire it/test it"...(first use 10 PSI though)..but my chamber are about 600cu in together and a 6' barrel to launch spuds. that MAX psi we'll use is probibly 100-110 PSI.

and the ones that I have say to wait 15 minutes for good handling strength and 2 hours for it to cure. I would never do this for a big gun, but I think I will try it for my little paintball pistol I am building--- the largest piece size is 1"

The manufacturer knows his product best. Lasco, for one, states in their solvent cementing procedures:

"...For most cases, 24-48 hours is considered to be a safe period for the piping system to be allowed to stand vented to the atmosphere before pressure testing!"

This is, of course an extract, visit their site (click on SUPPORT CENTER) for a lot more useful information about PVC.

As boogieman and others have stated: "WAIT!"
