EDIT: Nevermind, my picture sucked.

HOLY SHIT. ABS = BAD. STOP FIGHTING.

Hmm not a bad idea, Any idea's where I can get some oompa loompa's?

I'm short and fat, so I believe I can help.

JUST STOP ARGUING.

I GET IT. ABS SUCKS.

Seriously. I know that and I have learned that ABS is not the way to go, so you guys should stop arguing.

About five minutes ago I shot a couple potatoes. That was really fun considering I haven't shot potatoes before. They are my prime ammo right now.

The only downfall is I couldn't see how far it went. It just sort of disappeared into nothingness.

3"?

Three inches? Because I don't think that it really matters for one part. From what I heard is that it's OK to have certain parts made out of DWV.

That's got a HUGE recoil/kickback man... My spudder has virtually none.

Holy crap man! You have so many spudders!

But I'm not complaining. These are pretty awesome.

Dude! That is an awesome gun! How much did that cost ya?

Wow man! That looks sweet!

Looks like it's nice and powerful, but it is madly expensive. I love it though. I am going to apply for a job soon. If I get the job I can afford to make good pneumatics.

EDIT: Can someone link me to McMaster?

I discovered I actually had a Solenoid valve laying around in my garage that worked perfectly.

Haha, Thanks loads for the help man...

We did have a problem with the elbows as we had to remove the pressure gauge before we could unscrew the solenoid. That sort of sucked.

Mostly the problem is that Home Depot only had DWV pipe. What stores sell SCH-40?

I think you guys are overreactingting a little. Sure, it's dangerous but he did a damn nice job. Stay below 40 psi, if possible lower. I took a gun made entirely of DWV to 100 psi several times.

I expect to see some more good cannons out of you.

Thanks man! It is entirely made of DWV...

I'm ...

Since you have to use it, pressure test it to "X"PSI and fire it remotely. Then just fill it to like 1/2 that at the science fair. And preferrably fire it remotely their and keep people away.
For future reference though, use Sch40 or higher PVC for pneumatics. Combustion can use either Sch40 or ...

That's 50 bucks down the crapper!

Is there any way to make sure that It won't blow? Like only using it to a certain PSI?

Because I need this for my science fair and my dad won't let me go get other materials... It's too late...
