Here's a little project I did one night after shooting my mauler cannon and out of boredom I went to Lowes and made it.
It works great!
It has a variety of barrels, 1", 3/4", Paintball, and semi-auto marble barrel.
Its completely portable thanks to my co2 regulator setup.

You can tell how awesome a cannon is by the pressure used.

That will look cool connected to a belt carried CO2 tank and small coiled connecting air hose.

Any idea how many, say 100 psi shots, you would get from a 20 oz CO2 tank and this cannon?

I have no idea on how many shots, but you have almost the right idea, I was going to mount the co2 in a satchel that I can rig to a belt

I made an Excel spreadsheet that can calculate that, I might post it tonight.

Great cannon, looks like fun!

Very slick. I like the stock; reminds me of Spudinator's hybrid. Can't wait to see the CO2 setup.
Stupid quote of the now:
joestue "The chamber is rated to 100 psi, it don't say that on the side, but the 2 inch stuff is rated to 300, so by analogy..."
"only the last two feet hear the end is black cellular core"
"I'm taking it to 300 psi"

What you should do is make shells out of a piesce of barrel and go with coupler shell coupler setup with a locking mech. On the inside of the shell would be like tape disk over back of shell wadding paintballs tape disk over front of shell. I also think it would look cooler w/o the stock but that's just me.

ya i agree, paint would look nice to hide that pink printing on the pvc, what about a barrel support? doesn't it flex and stress out the union/elbows without some kind of blocking between the barrel and chamber? I don't mess around with plastic, i assume it needs support wherever possible so it doesn't fail on me someday... just my theory anyways.
