Well this gun was made for $1.50 .
All I bought was the union, I had all the rest laying around.
Not much to say its just a chamber, union, and barrel.
I pump it up till it bursts no fancy triggering system.

specs
Chamber: 5in of 1.25in pvc pipe
Fill setup: schrader valve
Valve:1/2in union
Barrels:28in of 1/2in pvc and the other 36in of 1/2in sdr21 paintball barrel
Pressures used:100-150psi

And I also name this gun the simplest gun I have ever made

Pic time

the schrader and my glorious feet


And looking down the barrel

Edit:oh cool I have a blue star now

My first target was a soup can i was very surprised it went straight through both sides. shot done at 140psi.

Looks good. I just made something like this. How is the performance? What are you using for the burstdisk?

thanks for the comment.
Performance is surprisingly great, it shoots faster than the eye can see.
And Im using aluminum foil for burst disks.

Edit: i just GGDT'ed it and came out with 780fps at its maximum pressure, 150psi and a 2 gram marble.

Hey, that looks pretty good for a spare parts cannon . Another thing you might want to try using for a burst disk is two layers of bike tire inner tube, it bursts at around 150 psi in a half inch union.

haha nice little project you got there

thanks everyone
And potatoflinger Ill try that, ive been using aluminum foil because about three layers of it burst at 140psi. but I can imagine the innertube would seal alot better.
I have some damage pics ill upload them soon.

edit damage is now up

Great results talk about bang for your buck! or buck fifty.

thanks
I am currently editing the vid

Humm, classical music for your video sound background...other than some 1812 overture/spud damage clips I've seen, this is the only one I've seen that I remember.

Nice and simple, but I would suggest an epilepsy warning for the vid as well ;p

nice 8) make a mortar out of it by puting on a 40mm barrel or something. great for 1.50 . onya

PSP (plain simple powerful)

starman: I dont actually listen to classical music I just thought it fit well with the vid

JSR:elipsey warning will be put up if you explain to me why it needs it.

Cosmic muffin: I was thinking of getting a larger barrel for it but Im out of money right now so wait till next weekend unless I have some spare pipe laying around

spudfarm: Definately.
I will make a similar version in a couple weeks just out of metal so it can take some high pressure

I just use the basic "normal" sized marbels.
Before i was using smaller ones which fit nice in the sch40 but the "normal" ones dont , they only fit in the paintball barrel. Very nicely I must add.
Id see if your common marbles fit in the paintball barrel.
If they are very loose then they might fit in the sch40 but they will most likely be to big.
sorry for the hard to understandness of this post.
