lol next time upload the pictures in reverse

i want to see a picture of the whole thing, and why did you use a pressure guage that only goes up to 15 psi??

it's kick ass of you to make all of these tutorials

I think that it is pathetic to use small sprincler valve for tennis balls, specialy at 15psi.Combustion will be much more powerfull and chep for tennis balls.

the cannon os not ment to be powerful, it is ment to shoot tennis balls ~100 yards for dogs, not distroy things
The DWV on the side of the pipe does not mean it isnot pressure rated. a cut it off of a piece that said 260PSI the DWV on the side just means it can be used for Drain Waste and Vent the other piece also says NSF-PW on it

very good, although you could probly say just a tad more about the valve modification in your final "how to". and yes i do know that the "how to" for valve modification is already there. overall great job :D

...why would he tell how to mod the valve in this thread when the reader could just as easily head on over to the "modding a sprinkler valve" thread?

Actually, anyone know how they're calculated? I'm guessing 1/100 of a spudbuck per character or something?

Step Thirteen
Drill a 7/16 hole streight into the slace where you want youre gauge to be. then uaing youre 1/4" tap therad the hole. go in one turn and then out 1/4 turn to clear the threads.
does somthing seem wrong with that drill and tap to u lol...
a 7/16 drill is bigger than a 1/4 tap... when tapping you predrill the hole 1/16 smaller then the tap you plan on useing, not larger. so u put the wrong numbers for step 13. im a machienest so as soon as i seen those numbers i was like wtf??? hows that gonna work,lol

Obviously your not familiar with the NPT pipe thread.

For information on NPT threads, please refer to this article: <a href="http://en.wikipedia.org/wiki/National_p ... >WikiPedia Article - National Pipe Thread</a>

1/4" threads have a exterior diameter of .54"
