Re: FIRST air cannon robots PVC??

Our team is developing a cannon that uses almost nothing but KOP pneumatics, with the exception being our barrel and its mount.
This was indeed prototype 0.1. I used 8 KOP tanks in four parrallel circuits. I.e. two tanks in series feeding into a manifold with four inlets. The manifold was all 0.5" black pipe tees. I then used couplings to enlarge the opening to the 1.0" diameter for the sprinkler value. Not nearly enough air flow was generated to launch the tee shirt out of the 3.0" diameter barrel.

Prototype 0.2 used three 36" lengths of 1.0" black pipe in parrallel which fed into the sprinkler value. Now we had the shirt launching but only a few feet and a really loud harmonic reverberation in the pipe ala Big Rig air horn.

Prototype 0.3 can be seen in the CD media and is now linked in my original post.
