holy hell... i'm going to be 19 on Feb. 27..LOL!

ok i put a block of milled wood between the barrel. and i can notice a little faster response. but i have a big question. i am going to replace the dwv fittings with some pressure rated ones and i wanted to know if there is any way to remove the fittings with keeping some pipe?

i'm pretty sure that the nsf-p is ok for pressure i think, and the fact that it says dmv on it means that it is also ok to use in drain waste and vent applications but the fact that it says nsf-p on it i believe means you're ok. and as far as reducing your pilot volume i'm not saying eliminate the ...

thanks MrCrowley i'm just new and starting a new hobby.. so i will become better just a learning experience so i hope my first isn't a complete failure

ok on the end of the elbow it has "Blah Blah... and i see a circle that says NSF and a P in it but then to the right of it it says dwv... so that means that i'm screwed right? EDIT: after checking every nook and crany, i have concluded that every piece on this cannon are NSF-PW except for the elbows...

i'm pritty happy with the outcome i'll probably will re-do the elbows after i have some real fun with it.

and the hose is off now to keep ppl at bay..

well my compresser only goes to 100 psi anyways.. old POS

i can do that.

EDIT: just asking is it the joint that blows off or the elbow shattering?

kool how does she fire?

can't wait till i see some building

well... crap.. you think it'll be ok? or should i repair it... i guess the guy at Lowes lied to me...

yes the elbows are pressure rated. and i can shorten the hose and i probably will just mount on the valve but i cant complain with the results. (sent a orange about 150 yards.)

So here is my first cannon. Specs: Barrel: 2' of 2" Chamber: 2' of 3" Valve: 1" Modded Sprinkler valve thinking about painting it flat black.. http://i5.tinypic.com/7xkbko4.jpg http://i2.tinypic.com/6ksrd36.jpg http://i9.tinypic.com/6jx72m8.jpg http://i17.tinypic.com/72hnifb.jpg http://i12.tinypic.c...

.....suddenly one of the endcaps on the chamber blasted off blowing through his porch railing. Not kool haha. lol thats sounds bad.. i dont live with my dad i live in a dorm room, i'm 18. so i am confident i have used pvc before (plumbing, my uncle is a plumber..) so i'm good btw i finished today a...

ok i'm going out at lunch look at some local stores and if i dont find anything jus buy a valve from lowes, and otherthings!!!

what should the barrel to chamber ratio be?

hmm sounds like this will be an interesting cannon. do you have any pics of the pipe and/or fittings? how big are you planning to make this thing? oh and how much money are you willing to sink into it? (sounds like a lot. haha) answer these and we might be able to help you more :o oh and combustion...
