Post subject:  2X4 Cannon test

I'm building a 2X4 cannon to shoot a 15 lb 2X4 at 100 MPH. Using a Supah Valve and an 11 Gal bead seater with a 2" outlet. We got the 2x4 to 61 mph at 75 psi and a loose fitting plug. Here's the 1st test. The cannon is behind a tree. Testing again today at 100 psi with a tight fitting plugImage

The cannon did the job. Violent destructive fun. Fired from the back of a truck. The Supah Valve with electric firing was the key. Cost about $400.
