Too bad i ran out of particle board to shoot, as far as i know.

More news: I have fiber-glassed the DWV thickly which no doubt has strengthened it. Also, this will prevent the cannon from shattering, instead producing a tearing action. Finally, i have set my limit at 70psi, which is very much satisfying enough for my tastes, seeing as it can launch QUITE heavy p...

It would cost about 20$, it seems. Much better than a new cannon. I am also a VERY patient person, and hey, I'll learn how to wrap things in fiberglass while I'm at it, right?

Do you think it would be possible or even helpful to wrap the pvc joints in fiberglass sheeting (with adhesive etc....) to make it stronger?

At this point I don't even care if it explodes, because i am going to be behind a thick wall with a remote trigger and pressurizing system. I will just rebuild it with pressure rated parts if it does explode. I just want to get the most out of the components i have now so I know i didn't waste TOO m...

Yeah, it goes about an inch beyond the T. All The air seems to escape VERY quickly upon firing, though. Getting the spacers in beyond the T is very much out of the question, so forget it. Good idea though. Maybe I'll do it whe the T blows off the cannon.

Of course, such a venture would be quite foolhardy with a cannon such as mine.

I will be using a bumper (the piece of thick foam), specifically the one in the pictures, unless it doesn't seem like enough. It IS pretty dense stuff.

Sorry about the picture size(3872x2592), I took it with a Nikon d40x, which happens to be my second most favorite thing right now :). Also, i am aware of the DWV, but it was all that was at the home depot. It hasn't exploded yet! :/ Do you think it's possible to somehow swap out the non-pressure rat...

It doesn't vent fast enough.

UPDATE I will be using a pulley system to charge and fire the cannon from now on due to the fact that i am using DWV Tees and elbows, so there is no reason to fear me blowing my face off, or anything else related to the consequences of exploding PVC cannons. When or If the cannon explodes, I will r...
