I always wait 24 hours for my guns to dry after being primed and glued. It's what I read and heard when I started making guns. Recently, however, I heard theres no need for a 24 hour wait. I knew from personall experience that once you put the pipe in the joint with prime and glue, you have around 3 seconds to get it situated.

I may get bashed or looked down up, more so than ever, but if I primed and glued the gun, let it set for around 3 or 4 hours...would it be alright to fill and fire?

I tried an experiment with two Ts and a small peice of pipe. It sat for 3 and a half hours, and I could'nt pull it apart, twist it, turn it, or even make it budge. But, I do know the practicle road is wait the time out.

Still be nice to get some outside input.

i use this stuff called pvc weld, it pritty much sets instantly eg.2-3 secs,so i also have to be pritty fast

After 1 min you cant turn it, i usally wait 4-5 hours and use mine, but if it is your first time wait 24 hours, and then as you get better glueing it wait a little less, for air cannons and hybrids i wait 12-24 housr becasue of the high PSI

Yea. I waited around 3 hours cause this was a smaller cannon, similar to PC Guys Battery cannon. Lost number count on gun though, guess this is my 11th 12th?

PCGuy doesn't post any cannons. For somebody's cannon to be included in the official cannons sections, it has to be submitted, then PCGuy posts it in the section it belongs in.

Click other, then Click on PCguys cannons. It's in there, he talks about it and has pictures of him with it. He also talks about how he doesnt do many to do the bindings of his towns legal limits man. It's there, trust me.

Ok, I looked and found what you were talking about. I'm just used to noobs coming on saying, "I want to make a gun like PCGuys Pumpkin Launcher!!!! "
Sorry

is it worth risking a fitting flying off? then you'd need to re-do the whole thing, just wait the 24 hours and be done with it, i find it best to solvent weld the pipes after i get home from school thursday, so after school on friday i have all weekend to play with my new toys

Yea, I usually wait but I don't a have another day off for a while, lol. It held up fine, just another simple ass gun from scrap parts. Was shooting cranberries and batteries for a while today at 100 psi. Held up fine.

SET time is much different than CURE time. Never confuse the two. The joint usually sets in less than a minute and can't be pulled off by hand or most tools. Cure time is the ammount of time it takes for the solvent to completely fuse the pipe and fitting together. This is usually a full day. It takes much longer in colder temperatures and warmer temperatures are generally shorter but don't push it.

As I said, I did push it. I was'nt too concerned is a fitting flew off this small little ball valve action battery cannon. I still wait 24 hours for the gun to cure before firing it, but this was just a scrap gun...and I wanted to shoot batteries.

My local plumber says 3-4 hours, What we here do in New Zealand for spud guns is just to coat both joints in PVC cement called "Rectorseal". No primer, just wipe, coat and twst it...Have used it in my Pneumatic and have taken it up to 70psi with no leaks..
