SpudFiles

Hey everybody, I've been reading spudfiles for a couple of months. From browsing the forum i've seen that this forum is nicely run. Anyways this forum is for new cannons, so without further adieu;

Iron/Steel/Copper Sprinkler Valve Pneumatic:

• 1-1/4" Galvanized Steel Tank
  3/4" Connections/Nipples
  3/4"-1" Elbow
  1"\(25mm) Orbit 91101
  3/4"x23" Copper Barrel

Full Shot

This is my second working pneumatic, my others were all copper, and sweated, but we're unfortunately left outside

My running pressure is generally 115PSI (10BAR)
My Ammunitions include: Grapes, AA Batterys, Baby tomatoes, markers.
All components are Pressure rated for 115 Psi, except the blowgun
Any comments or suggestions are appreciated, thanks!


P.S: I appologize for crappy webcam pictures, better them then nothing.

Cool gun(s)! If I were you, I'd research piston valves, and make a metal one for this gun. If you did that, you would be able to use pressures like 400 psi.

Sweet guns. I love the rifle style look you can get by using elbows. You shold make a piston valve for it! Piston valve=more power!
EDIT: noname beat me to it!

Could you get a shot of the entire cannon? looks pretty sweet.

Full body shot has been added, Thanks for the comments guys.

@noname: I've researched piston valves for a while, and i'm planning a metal 1" in the future, however, building your own valve requires definite planning, and I am going to take my time, for this gun, the speed and volume dump of the valve are plenty enough, thanks for the reccomendation.

I too would recomend upgrading to a piston valve. Even though I'm having terrible luck with my current metal piston valve (although nothing's blown up yet ) it seems quite a shame to have such a nice gun have such an unworthy valve. Sprinkler valves can only take a fraction of the pressure that a piston valve can, and the sprinkler valve is only holding the gun back from being able to take more pressure and thus, be stronger.
Regardless, it's still quite a nice gun! Do you plan on posting damage pics anytime soon?

its nice I would leave it sprinkler for now and build a new 1 for a piston ps this is sent from an iPhone wood

Perhaps get a QEV for this thing? I'm sure they can take a load more pressure than a sprinkler valve. After that you should get a shock pump to get up around 300+

Oh yeah? Well look what I can do ,'.,.'',.,.'',.',.',.',.',.',.'.,',.',.',.',.',,'.''.',',.','.',.',.',.'.,'',.',.'.,',.'.,
let's see you type punctuation marks like that on the iphone interface

The blow gun can handel alot more pressure than indicated....."they" just say 90 psi or what ever..... for liability

I agree with the liability on the blowgun pressure,
currently the sprinkler valve is fine, I have yet to experiment with qev's. I'm currently planning on a 2" piston, only problems are:
Budget (saving for car)
Must be in a metal housing
withstanding 200psi

the planning i'snt as hard as actually implementing it, but it will be finished eventually.

thanks for input guys, hopefully i'll have a new cannon on soon.

love the sprinkler valve cannons... Im building one right now; I'll post when I'm done
