Not bad, i would consider modding the valve with a trigger, or if you want to go farther you can completely mod it further. follow this http://www.spudfiles.com/forums/how-to- ... t7038.html and you an get better performance. Nice first cannon thought.

Looks like a pretty sweet cannon! You shouldn't have used DWV prrts for it though. If possible, rebuild the gun with pressure rated parts so it'll be safe to take it up to higher pressures.

Not bad for a first cannon, especially with the size.

DWV kills the whole project though, if possible rebuild, like iPaintball mentioned.

Read up on moding your valve, even at the save pressure of 60 psi, you will see a significant difference in performance with the size of cannon you are working with.

BTW, how long is your barrel, and does it accept other barrels?

the valve is triggered by the remote switch in which a 9 volt battery is wired to a switch wired to the valve

Your solenoid isn't 24 volts?

I thought 24 was the standard, but if it works...

You seriously need to cut off those DWV parts and replace them with the pressure rated version of the same thing. There have been a couple accidents lately and we don't want more due to unsafe fittings.

Comments: it's Awesome! Love to see some damage pics and maybe a video.
Also How far does it Shoot?

Improvements: Mod the Sprinkler Valve with a blowgun trigger and on your next gun try and avoid DWV but this cannon should work fine.

Great job For your First gun.

Happy SPuddin'

Edit- @battlemonkey, I have a twelve one too. I'm in AUS I think it's the standard for Down Under.

Read the fine print in the instructions they say 24 volts ac 9 volts minimum and 9 volts dc is enough to open it one way when u flip the switch and it closes when u turn it off.

Yes, but you can get faster actuation by using more power.

You guys are qorrying about the least of his problems. Cut off the DWV before you kill yourself.
