For those who are interested, today we were at the school filming for a show for the local cable company, and we found the new system actually works better than the co2 did. We shot quite a few shots (more than a 20oz co2 tank would have allowed, I think) and the cannon shows a range between 40 and 60 yards, while the best we got with the co2 system was around 30 yards.

Where did you get the release valve for the launcher? Is that a pneumatically actuated gate valve?

Great looking launcher!
