My first air cannon

[starman]

Actually, I have seen way uglier and far more unsafe cannons than this. The T-bone configuration of the tank is what's weird to me, hard to hold, aim, shoot, transport and store.

Hey, you did what 90% of everyone who starts out does. You can learn from it and move on to better things.

i would use PVC rather than DWV though its a very nice design

Ah... DWV is PVC.

Learn your facts before telling others, passing around bad info isn't good at all.

Yes I agree this cannon sucks , but still, I made this cannon a WHILE ago...way back in 7th grade! (I'm in 10th grade now).
this cannon might suck comparatively, but personally, I don't think it sucks for a 12-13 year old with hardly any help.

hehe don't get mad get glad, I like it, make a better one, the valve is the only expensive part.

Indeed, this isnt bad, but i dont get the T formation, why not just add 2 90's? good for a first though =). Before you go ou and spend your 200$, read through ALL of the wiki and actually plan what your going to do, it helps and saves money.

Did you get this idea from Backyard Ballistics? Good beginner's book, but the cannons aren't incredible If you did this when you were 13, I'm looking forward to a current project!
