I think you should secure your barrel so that it doesn't flop around when you shhot somrthing, beceause thats what it looked like in the video.

Nice simple and powerful cannon !

I like it.

And I agree, you should secure your barrel ...

what kinda of valve do you use an you larger gun

I like how you spelled "potato" wrong twice in two different ways. Hahah!


It seemed to me that the same clips were repeated a lot but man that flying plywood one was awesome.

And you are aware that using DWV on a pneumatic is bad right?

[WOW!!]

Its not DWV, all pressurated sch 40,

I like how you spelled "potato" wrong twice in two different ways. Hahah!
lol

I have a thing to sucure the barrel but i didn have the other tank on it, and yae he same clips kept repeting, i have to get more footage of it. thx for the input.

Cool cannon, i'm glad the video was windows media player so i could watch. GOOD ONE!!!

Sch 40 doesn't mean pressure rated. If it doesn't say PW then it's not PW. Those bell reducers are only used in DWV. I think you'll be fine though.

[WOW!!]

I know that, but it is all Sch40, i would use non pressure rated pipe anyways or fittings. Because i remeber picking up and DWV one and it was thinner and then found the Sch40 one.

Most cell core is sch 40. "Sch 40" Doesn't mean shit as far as ratings go... it's just a freaking wall thickness!

Not all DWV is created equal. Some <i>is</i> better than other stuff.
Doesn't mean the "good" DWV is safe for pressure, but just don't stand inline with any of the fittings of the gun, have anything of value in line with the fittings, put any body part inline with the fittings... and you'll be fine if the joint does fail.
Sounds restrictive? Then shell out the money for PW parts you cheapo! (though those are still good guidelines to follow even with PW parts...)

sgort, acctualy, I think there are pressure rated bell reducers. They are just ultra-rare.

[WOW!!]

Woops, what i ment to was i would NOT use any non pressure rated pipe.

sweet, nice video.

I used to say prettymuch the same thing you are saying WOW and then I had my launcher fail on me and throw a 3/8" ball valve, tee, and elbow back about 15 feet. From there on I realized sch 40 means nothing without seeing the letters PW on it.

How about you assure me it says PW on it (actually check) and I'll shut up and quit worrying about you. If you can't find "PW" on there then I'd suggest turning it into a combustion and getting yourself some new parts for a pneumatic. Continue to use at your own risk.
