You're saying you want to build something like this, yet something completely different???
I want a black Mercedes, only built by Honda to resemble the General Lee...

What ever...

And Taz22..I doubt a blowgun will have enough flow.This gun can take pressures of over 300 Psi( 21Bar) so i think a ballvalve would still be the best option.( unless he can get a high flow fire-extinguisher valve, and the fittings to attach it)

I got my 20oz paintball cylinder. AND! it has 1/2" threads, which is great because it should be easy to install on my cannon.

Now it is just the trouble of finding a regulator over here. I attached my fire extinguisher to the cannon for multiple shots, just until I get the co2 running. But it isn't great because of the 50 psi limit. I love my cannon.

A footpump would give you more than 50 psi.

NO! Regular regulators are meant for like 200 psi max, Co2 can get to 3000.

im not 100 percent sure, but i think most pb co2 cylinders are regulated in the nozzle, i doubt they output 3000 psi even if that is what they are holding.
also im pretty sure your basic 50-80 dollar cylinder isnt filled that high...
but i could be totally wrong

They are filled to 800-900 psi, but (according to frogy, who works at a paintball place) Co2 tanks have a 3000 psi "burst disk" that sometimes ruptures. Heat changes everything. As for the output, I'm not sure if they are regulated down or anything, they might be.

Still you need a Bulk tank reg or A paint ball one to get it right.
