What size barrel? My first one looks just like that with a .5" barrel and ball valve and a 1.5" chamber.

Good first cannon, just ease up on the primer kinda hard to paint over. If u decide to paint it use Krylon Fusion works great.

Cool gun. Its a lot cleaner than my pre-spudfiles pneumatics.
You should post some damage pics if you can.
If you have time you could make a spring loaded trigger for the valve to open it faster. It really helps if its hard to turn, plus its easier to aim.

Edit: Also, how long is the barrel?

It's an ordinary ball valve. Obviously made of PVC, probably sch. 40.
Please read before you ask a stupid question like that again.

Great job on the gun. What does it shoot? HA HA HA HA HA

oh yeah. Nice firstie gun. Next time remember to use bushings instead of bell reducers. Bell reducers aren't pressure rated(usually) and create a small(and usually insignificant in a first gun) saftey problem. Nice job.

Another tip from me would be that it would be nice to see some puncutation and capitals.

And to the noobs: STOP FLAMING EACH OTHER!!!

Back to reality:
Your pneumatic sort of reminds me of my second cannon. (My first cannon was the most ghetto cannon that never won Sgort's coveted prize. *sob*)

You did overcook it on the primer a little - you've got it a quarter of the way up your chamber!
Next time, be a little more sparing.
