If I didn't have to work for a living, I could sure have fun building stuff like this.
Description of top one: The barrel is 10 feet long and 8 inches in diameter, and the entire rig is over 15 feet long. The pistol’s grips, which cover the firebox, are made of red oak. When cooking, the barrel acts as the grill’s chimney. It took over two years and 1,100 hours to complete, and used more than two tons of red oak, stainless, and carbon steel.
