The small gun is 20" long and has a 3/4" ball valve, that I will be changeing to a modded sprinkler valve. The big cannon has twin 4" tanks 5 feet long, and can eather use 1 modded sprinkler valve for one tank or 2 ball valves for both. It put D batterys thought 3/4plywood with one tank.<center>

I believe the tee on your small cannon is DWV, and why is their duct tape everywhere, electrical tape looks cooler. What are you launching with that massive bolt.

Lmao, it I made it when I didnt know what I was doing and I had extra duct tape lol. The Tee is Sch40 DWV, it is Pressurated. The small one was when I didnt know how to build them and I thought over 40PSI it would blow up, :oops: and in the instructions it sayed to duct tape it like that. I am going to take it off since I know that if it brakes the wall of PVC, duct tape is not going to help to much.

And the reason I dont have a longer barrel is to save space. It is a shoot and run kid of deal(But I would never shoot anything were when I was done i would have to run :twisted: )
And the breech works really well, there is no air leaks. Iam building a Hybrid right now so I havent put to much money into them.

EDIT: I forgot, I launch PVC rockets,they work really good.

DWV isn't pressure rated even if it is SCH40. SCH40 is a classification of pipe dimensions, it has to say PW in order for it to be pressure rated.

And he meant that instead of creating a situation where you would have to run, you would finish the job nice and clean... like a mafia hit or something... idk. But with something like that, it's not hit and run, more like, hit, drop and run.
