A 5 gallon should be fine, how long what? It depends how high(PSI) you charge the compressor to, how much PSI you put in your chamber and how big your chamber's volume is. With my gun which has 2 1kg fire extinguishers as a chamber I get about 3 or 4 shots of before my compressor hits 60psi if I charge it to about 115 and regulate it at 85-ish PSI.

Okay, I went to Lowes and their only blowgun was rated for 90 PSI. I plan on going around 120-30 PSI or so. Will it hold?

Also, can anyone give me a complete list of the parts I need for this tutorial? I want it to look exactly the same as in the last picture. I am having trouble picking out a final parts list.

The blowgun should be fine, it's just the rating of the internal parts and such. The only thing that could happen is you take it too high and mess up the seal.

Hey i am new to this but with that kind of valve you can plug the hole where the solenoid is and just screw the wide end of the blow gun directly on the valve

i think you are refering to either the solenoid or the manual bleed valve, in my opinion i would take them out (solenoids leak slightly & manual bleed gets in the way) but if its your first time just leave them in there till you have learnt a bit more about them and how they function.

im about to make my first pneumatic cannon and i understand how to mod the valve pretty much but i am con fused on step 6 & 7 on step six the adaptor has this thin tube on the end but then on step seven after youve threaded it in it all of a sudden has a barb on the end. Does the male barb screw into are somethin :?:

You have to tap aka thread the 1/8" fitting into the top of the valve. In this instance the fitting with the thin tube was put in the drill for easier threading. You should watch the video here

im not sure what you mean by a barbed valve, but maybe you meant a barbed hose adaptor. if you use a hose then you should, but if you just used a nipple and 3 or 4 hose clamps that would probably work to, but agai the barbed adaptor would work best.

you also dont even need to use a hose, just tap a hole and screw a blow gun in.
