Thanks tons for the effort. Here's couple of pics of my cannon, set out as part of my pirate-themed Halloween yard haunt. It's the same cannon, evolving over the last three years. A 12-inch speaker is at the end of a matching-sized concrete form tube. A fog machine on a timer is concealed in the gun carriage. The fog is blown into a 3" wide galvanized tin elbow mounted underneath the barrel. The speaker is hooked to my stereo. The "bark" is provided by a looping wav file of a howitzer being fired, followed by two minutes of silence. As you can see, it blows a pretty decent smoke ring. At night, a small sound-activated LED strobe is placed in front, facing the end of the barrel for extra effect. Enjoy!
Step two part three about where the bungee cords go was extremely vague and yet has a major affect on how the cannon works. I expected better detail from you.
