semi-auto or bolt action

Cannons powered by pneumatic pressure (compressed gas) using a valve or other release.

Is it possible?

Do you have any suggestions of what to use for a bolt?

realy you just have to look around but like i said if you cant find anything just mold one with like hot glue (i dont know if you can drill though it though) or epoxy would work

I did use cooking spray, but it still didn't come out. Anyway, I'm using a wooden dowel that fits nicely in the barrel. All it needs is a hole in the middle.

GAAAHHH!!!! that will reduce flow like a Mother!!!!!!

use the brass tubing. sure, its expensive, but your preformance will not drop because of it.

either that, or you get veneer tubes. or, you can use ur idea. whateveres best.

if youre still gonna use wood, i reccomend drilling lots of small holes, not one HUGE one, it will maintain streingh better.

Wood will NOT make a good bolt as it will choke the barrel size so much, its pretty much guaranteed to rip it out of the barrel and ruin the barrel end of the gun.

Hot glue would again have the same problem that the wood would have, it would choke the flow down and tear the gun up, and drilling in too many holes would just make it like a bit of rubber in the barrel, that will be shot out eventually.

Like suggested before, use brass pipe that fits inside the barrel and what not. But some smaller PVC pipe will suffice too.
