I have built one cannon before this one but I did not design It. So this is my first cannon that I have designed and built.

Specs:
Chamber-16"by4"
Barrel-(detachable) Sch 80 3/4" by 5'(paintball) and 1 1/2" by 6"(potato)
Valve-3/4" Aluminum QEV

In two of the pictures you can see my other cannon that I built from plans in a book called "Backyard Ballistics."

*Sorry about the pics I can't figure out why they are doing that. Before I upload them there was no white.

haha..... really though, what has he made. All he posts is insults. Pie, if he posts crap on your thread ignore it. He just wants to feel better about himself.


Your cannons look good though. Nice job, keep em coming!



By any chance did you copy your pics into Paint and forget to trim the edges? That might make them like that.

Nice gun, I find 3/4" QEVs very powerful for small bore barrels.
If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!

Where are ther DWV Fittings BC. I just rechecked all of them and I am pretty sure none of them are.

edit*Oh just realized that you were propbably talking about my old one. Sorry if you were I thought you were talking about my new one, and I really don't want to have to take it apart. But yeah there is alot of DWV in my old one. It even has a super high tech chamber made out of Cellular Core ( :wink: ). I didn't know any better at the time so I used whatever was the cheapest.

Wait are you talking about the old ball valve "T" shaped one. If so I know this and that is actually why I built my new one. If you are talking about the over-under one (the one this topic is about) please tell me where because I have thoroughly searched every fitting twice now finding that all of them say NSF-PW.
