Spencer wrote:Awesome. Just one question. If you are using 2 1 inch valves then you have a total airflow of 2 inches. As far as I can tell everything on the barrel side of the valves is only 1 inch though. Arent you constricting your possible airflow?
But are the diaphrams in the valves actually opening up to allow that kind of airflow? And maybe by having a smaller opening after the valves (maybe 1.5 would be better than 1 though) would help to keep the air at a high pressure. It just seems that if you have the valves dump into to big an opening, it would drop the pressure and hurt performance.

You never cease to amaze me.
from the two chambers to the two sprinkler valves connected to one blowgun.
just wondering two questions.
1) how much time did you put into this project?
2) how much money did you spend on it? not to be nosy or anything. If any offense is taken, I apologize in advance.

i made a gun just like that but it has 2 1' by 3" air chambers it looks just like yours but i screwed up on some fittings so it is a bit longer than i wanted it to be. but i cant get my gun to fire, the diaphragms don't go back up when i squeeze the blow gun all the air just comes out the blow gun i need help fixing it and i have no clue why it does not fire. so i cant fire my gun :cry: :( if anyone nows why just send me a message or sumthin. thanks :!:

you should make some 1 inch PVC missles as ammo. If you can plug the front of em they fit nicely in the barrel without any work. Imagine the damage witht that! Anyway, Sweet cannon, Iv'e always wanted to make a gun with more than one vavle. Also, I dig 1.25 inch PVC barrels. it fits..... PVC MISSLES!

If you read the previous posts( from more than three months ago)it says that this is evileyemonkeys gun and he dosen't post here any more. And if you want to tell us about your gun, post a new topic.
