Unread postAuthor: demilus » Wed Apr 12, 2006 9:57 pm

what would be the perfect ratio for a pneumatic cannon with a 10" long 2" wide resovoir to a 2" barrel at 100 psi?

no larger than 1 inch
maybe you could have a paintball barrel(3/4" cpvc)
half inch for batteries AA but 3/4 or 1/2 would give you good performance

Andrew, that wasn't his question.
Using the <a href="http://www1.iwvisp.com/thehalls/ggdt/index.html">GGDT</a>, you want ~42" of barrel.

What ratio are you using? If his barrel is the same saze as the chamber, why would it be longer? Sorry if I misunderstood something here.
