Simple cannon

Usually people build ballvalve cannons as their first pneumatic. This is probably my 8th completed cannon and my first ballvalve. I built it just for fun and I'm actually pretty happy with it.

Specs:
-1 1/2" x 10" chamber
-1/2" x 24" barrel
-Schrader valve
-3 minute paintjob

Please don't suggest upgrading to a sprinkler valve. I simply won't. I wanted a ball valve cannon and that's what I have.

Also, would it be safe to use this even if I happened to forget primer on the pipe connecting the bushing to the ballvalve?

wow, you could put a sprinkler val.... Only kidding! Looks like a blast: nice and simple. Getting back to the basics. Nice work.
What are you using as projectiles?

Cool paint job, it looks pretty nice for a three minute job.

If not a sprinkler valve, at least get a better ball valve! The metal ones with the big handels should give you faster opening control, and you can easily spring load them! :D As to your primer situation, I wouldn't trust it on holding, but my knowledge of working without primer is non-existent. :oops:

I have had a cannon never blow(minus a cracked threaded fitting) and I didn't use primer on it, and it was 2" pipe.
so you should be fine at 90 psi.
