Hey you guys this is going to be my Pen cannon when it's built
![Smile :)](./images/smilies/icon_e_smile.png)
. So I have 3 different barrel sizes 2 are long that i got from school and the largest one is from my bb gun. For the shredder valve I have a tire valve. That I will shave the rubber off so it's just the metal. The piston I'm still not sure on :/ to get it tonthe right size and to last because it won't be servicable. Another problem is I can only fill it up to no more than 200 psi.
Alright enough of my dum blabiling here are some picture od the barrels. And the pen I would use if I am to use the 2 smaller barrels.
Oh and i'd use epoxy to hold the valve and epoxy at the end. Supported?

That's the wholes the pen has I'd cover them with jb weld
