How do I make a burning barrel from an oil drum?
Turn your drum upside down and drill several small holes around the bottom. These air holes will help keep the fire going, furnishing enough oxygen to the bottom of the fire as long as you don't pack too much wood in the barrel. I chose to drill about twenty holes around the edge, then a few in the center. Just make sure you put the barrel up on concrete blocks and make sure your barrel is LEVEL. Nothing worse than stirring up your fire and have the barrel tip over. My own county has restrictions as to wind speed before a "burn day" is even allowed, so check this out before you start your fire. When your fire dies out, spread the ashes around your yard, the grass will love you for it. Water must be handy all the time. And remember, don't look down into the barrel with a hot fire blazing ... it's bad for your eyebrows.
Growing up, pretty much all there was too it was throw stuff in, add a little lighter fluid, and light it on fire (I assume you are referring to trash disposal?).
You want the area surrounding it it to be mowed for at least about a 10 ft radius in case of flaming debris, and it's a good idea to water that area down first too, as well as having a fire extinguisher handy just in case.
