1.) so far only 1 2.) decided to build a large pneumatic piston valve out of DWV and pressurize it to 115 psi 3.) The valve ripped into pieces shooting shrapnel everywhere. we found pieces like 100 yards away. Lucky no one was injured, just a few bumps and bruises. 4.) Tore down and removed all non-...

lol idk.. like i said i was just bored.

that is a beautiful thing. It must have been fun paint balling with it

yea no kidding. I'm willing to bet there's hundreds of plumbing supply centers around St. Louis. Its just finding the ones that carry what you need is the trick. And once we get the proper pipe.... helium might be an issue.

But we will prevail!

well... thats a friggin awesome camera.... i wish i had $1k

i wonder if you can rent them from someone?

anyone know where we could get a high speed camera?

Imagine the damage shots on high speed.......

thats a bummer dude.

it was because of help from my friends we were able to build such a large and extreme cannon.

of course everybody here at spudfiles helps with all your cannon needs... so its kinda like people to build cannons with, just not physically.

i was thinking about that, but i think the piston would slow down quite a bit from the compression from the water down to a 3" hole. I only put one vent in b/c if you start adding more, more water would be lost as it passes it. I was also thinking of even eliminating the open air hole and putting a ...

yea thats what we're planning on doing is buying it from bcarms b/c right now our golf ball barrel is meticulously short.

it may have been a bad batch. but its kinda odd that all the sdr-21 pipe this place had on their lot was the same dimensions. Of course it could change between manufacturers, but even so, the pipe we got a year ago was the same maker but the right size. so i dunno

well that piston was dangerous b/c we used dwv

sdr-21 doesn't work anymore.
DonTheLegend and I bought some like a week ago and it seems like the standard changed

lol well i'll have to research how to fire a stream of water. it seems like i would be a little difficult because of the air from the cannon mixing with the water and just making a mist cloud.

maybe make a piston barrel?

Hey guys, i was bored so i decided to create a spudfiles page on facebook. Check it out, become a fan, post stuff.

hah

you'll soon see on the news:
