Re: Optimizing Air Cannon Range

We just built an air cannon to fire confetti.. with a delrin projectile we got something like 80-90 ft of range..

I agree that the biggest problem is the valve.. We got a manual-open spinkler valve which seems to work better than the solenoids (which seems to "honk" as others have said) to be honest, the best solution is to use a large valve but those are hard to find, and diaphram types seem to open faster (from what I've read)

we'll be improving our cannons (we have 2) so I'll keep posting.
