I cut off the air chambers,and added two 5 foot long,6 inch diameter sch40 air chambers thats 10 feet of 6 inch pipe! I also got a 15 foot long,4 inch diameter sch 40 barrel.I panted it flat/primer black .It looks sooooo much better than before

Hey, i wanted to use the same valve for a smaller version of this. I just have one question, What do you use to seal the left side of the 4" tee?

oops, I forgot to put the 4 inch to 2 inch adapter on the diagram! in order to get the pipe to slide through the adapter,you must use a dremel or rasp to grind the lip out of the inside of the adapter where the 2 inch pipe goes through

thats asome but you should have used a larger barrel to shoot bugger potatoes.
A coat of paint would look nice

I do,I have a 15', 4"diameter barrel,a 10' foot long,3" diameter barrel,and a 1 1/2 " ,15' long barrel .I painted it flat black,nnd replaced the air chambers with two 6" diameter,5' long air chambers.If you thought it was huge then,wait untill I post a new thread with updated pictures of it in its current state

just think a 50 foot long Paint ball barrel.

Thats a big cannon! Well done, especially for someone of your age.
Maybe you could slap on some paint.

One minor note: about time eh? With 1600 posts posting your first cannon...

Um... this was posted over three years ago mate. He didn't have 1600 posts back then.

Hehe, even some of the veterans accidentally kick up a dead topic!
I'm guessing you came here from the thread about barrel droopage as opposed to the random cannons section, which is unusual. I think this highlights the need for some sort of reminder what you go to reply in an old thread that it's old?
Regardless of how many posts, it's still very advanced for a first cannon, a lovely specimen.

nice job. Thats a true beast!

Lol! How the hell. I kicked up a dead topic!
How did that happen?

Sorry! To compensate this, I will post some neat damage pics soon, hoping you guys will forget this fail.

EDIT:

Yes.
The point is that I always open every unread topic in a new tap and then simply read and post them one by one.
I clicked a link in the barrel droopage thread, and fergot to close the tab, assuming it was a new topic.
I was already like: huh thats odd.

And the Lord said, "schmanman, rise and come forth!"
