while the gun looks good i think the chamber is unnecessarily large. The U-connector made from the two 90° adapters is way too small, making a bottleneck.

In any other cannon with a longer barrel this wouldnt be a problem, but the barrel is so short that there would be a hell of a lot of wasted air inside that chamber.

Anyways, it looks good so if u can overlook that small design error then its alright.

the bottleneck occurred way before the two 90 elbows... the sprinkler valve! there is no way around the bottleneck and it actually makes more sense to keep the same pipe size as the valve until you hit the barrel. also, how is the chamber unnecessarily large?

maybe you shouldn't start off your posting here with complaints about other, much more experienced people and their launchers...

Nope. That happens to be a safety pop-off valve. Basically if the pressure gets to high it opens so you don't risk blowing the cannon (and yourself) up. On the other side of the cannon there is a pressre gauge and a schrader valve to fill it up.

Like two dollars or something. Go to an autmotive store and get the pop-in tire valves. They are really easy to put in your chamber.
