SpudFiles

Hi This is my first gun that i've made.
It all started when we were doing hydraulic and pneumatic projects in science class(I am in Grade 8)so i had the idea for a pneumatic powered spud gun.It was a good choice, i got a 98%.

The air tank is 1 1/2 Abs
The barrel is 3/4 pvc i think(its white)
It uses a 3/4 not yet modded sprinkler valve but i will be soon
For now im using a wall adapter with converter for the solinoid

I use the pressure gauge on my compressor so there isn't one on it
I also have some damage pics at 10 psi!

.....Yes im only 13

Get rid of that ABS immediately. It isn't made for pressure and should never be used in a pneumatic.

EVGman,
Sorry to say, but noname is right. The black ABS pipe is NOT pressure rated and IS NOT safe above about 60PSI. You should switch to NSF-PW PVC parts. If they don't say NSF-PW they're not pressure rated (even if they're SCH40, that's just the wall thickness, NOT a pressure rating).

Nice design, clean construction. Keep it up!

Peace,
Pete Zaria.

that is a nice gun except for the abs i agree that you should change the chamber

Good Idea
The only reason i used abs is beacuse it was the only one i could find!
I don't go over 40psi tho even

even if you're only using 10 PSI, ABS is very risky to use on pneumatics. But with your build layout, it shouldnt be too hard to replace with NSF-PW parts.

But like Pete Zaria said, MAKE SURE IT HAS THAT WRITTEN ON THE PIPE! Some pipe even say what their PSI rating is. I always use pipe that is pressure rated to 260 PSI and pressurize it to a MAX of 200.

Stay safe!!

If hes staying under 40 psi then theres no need to switch, as long as he doesn't leave it pressurized for a couple of hours.

Dude your tiny!!! Nice cannon though

that is a huge cannon for a little chap
i like the design tho good job

I'd definitely make the recommendation to switch to pressure rated parts for your next cannon. Other than that, only thing I need to say is that the name is... taken already.
