first cannon, i need help.

Unread postAuthor: edyo » Sun Jun 04, 2006 6:00 pm

For my Physics project we need to build something that will launch something 100 yards. So I decided to build a spud gun. My dad and I built it out of ABS and i was wondering is ABS good enough? Will the ABS withstand the pressure? It is a combustion cannon, the chamber is 3" and the barrel is 1.5". Its coextruded ABS celluar core DWV SCH40 pipe. So if you know anything about this please help me it would be very appreciated. By the way im a senior in High School so thats why i need this. Thank You.

You need to research the Spud Wiki at the top off the page to the right.

Pimp, ABS by itself is OK but Cellular core is cuttin it a bit close.

Edyo, I'd go out and find some PVC or ABS with a decent pressure rating on it. Take the gun you have now and have as much fun you can with it and a cement patio. :wink:
