I have been racking my brain at times trying to come up with an inexpensive, easy to build fireplace. Then it hit me. Using a 55 gallon drum. The top already has the hole for the smoke stack. All I would need to do basically is cut a good size hole on the side for the door, and to put the wood in, and setup some kind of shelf to put the wood on, so the fire would be more center than at the bottom. Not only that, it would be mobile as well. Any suggestions would be greatly appreciated.
