Epoxy Puddy Strong enough ?
Hello, I made my first pneumatic cannon the other day and it was pretty awesome until one of the fitting came loose. I used the 2 part purple primer(cleaner) and pvc cement, now the chamber portion of my cannon has pvc primer/glue residue on it. I attempted to re prime and glue the fitting back on but it was no good. I have some EP-200 epoxy putty on hand and was wondering If that could stand up to the psi and be used to successfully re attach the fitting to the chamber.
Thank you,
Thank you,

I don't know about the putty but did you sand down the pipe before attempting to reglue it, from my expierience the fitting usually need to be replaced if the glue comes off
That is all.

Just chop the bad part of the pipe off and replave the fitting. Or go the unsafe route and sand it then re-glue it.... but I wouldn't. If you did a good job in the first place and waited for it to dry then you should have been fine. How old was the glue?

I suggest you read up a bit on how to glue PVC properly. A properly glued joint will never come apart.

I think I know what the problem is... after reading the links Jimmy posted I believe I was letting the primer dry out too much before applying the glue. Thanks for the lesson in pvc solvent welding. I might of known this if my primer can wasn't rusted and missing the label yikes.

Yes that can happen, some problems with that, I typically prime all my fittings then go ba k and glue the from first primed to last primed

When the solvents in the glue dry, the glue will not make a safe joint. Never use glue that is more then about 6 months old. It doesn't properly weld the pipe.
To test glue, smear a glob on a piece of scrap pipe, wait 30 seconds and scrape it off with the edge of a credit card (old one) and if just the glue comes off, it is bad. If it softened the pipe and you scrape off some of the softened pipe, it is good.

How come no one asked this one? How long did you let it dry?
My bet is you didn't wait long enough. Even bad glue will hold pipe together. It would just leak. Waiting only a half hour or so isn't enough for the glue to fully bond the joint. This results in maybe a couple shots working, then a loud scary pop out of nowhere when your chamber slides apart. Always wait a full day. Patience is your friend.
