What pressure are you shooting at?

... and why such a short barrel? and "bad" valve?

I'm sure it's fun, but I'm also confident you can do a lot better?

I shoot with 1 bar at the time...i know i can go MUCH higher.I take it easy in the beginning. The valve is not bad and the barrel is short becuse i took it from a thing that you hang clothes on!

Custom machined piston valve and much MUCH higher pressure. You could probably shoot a toothpick through a 2x4.

I don't know about a toothpick but you can shoot a Golf Ball at mach 1.04!

Tornadoes with 250MPH winds have put straw through barns. In fact, Mythbusters shot straw into a palm tree. The right speed for any given mass can be devastating. I'm sure the right set up could do worse.

I updated a picture today!look at the top!

I have made some adjustings on the cannon!pics will come a little later

Okey,i made some miscalculations,i said that i shot with "1 bar","1 bar" is actually 6 bars(87 PSI) ...

[AircannonSweden]

I "invented" a new barrel today,now i can shoot golfballs,sorry for a ghetto-barrel-figure-thingy... We don't have PVC-pipe in Sweden...

Does the golfball just roll out of the barrel when u release the ball valve?
