howdy im new to the air cannon world and im trying to build a over under cannon iv got everything done but a regulator and i was wondering if a pressure regulator from an aircompressor would work or would it blow either the reg or the cannon up

Hooking up a compressor regulator to a CO₂ supply would likely exceed its input specifications (800 psi+ when it's usually used at 150 psi tops), I don't think it would actually blow up but it probably wouldn't work very well after that...

k thx i didnt think it would now i have a nother question i put the reregulator on my cannon filled it to 100 psi it worked great no leaks when i fired it it launched the cannon about 30 feet from where i had it laying what happened the coupling i had glued to the pvc bloo off some how so i was woundering is the a special glue to use to hold the pvc together at such a high pressure

Are you using PVC cement and primer? If you are using it correctly, your joints should be stronger than the pipe.

thats a good question i cant remember i what to say it was primed but i dont know my neighbor is the one who glued it for me

I'm getting the impression you ought to do a bit more research before physically playing air pressure and pneumatic launchers...
