Things You'll Need
Instructions
Use the metal punch to create holes in the bottom of the oil drum. Once you created leverage to us the hack saw, make vent holes. In the same manner, make one large opening for the top of the drum. Stuff the bottom holes with ears of corn. The corn will keep flames from shooting out of the drum but vented enough to allow oxygen for burning. Place 3 or 4 large stones in a circle and place the drum on top. Fill the drum with corn and set on fire. Cover the drum with the sheet of metal. Place 1 or 2 stones on top to hold it down.
Let the fire burn until the smoke disappears. Once the corn cobs have cooled place a portion of them in the plastic garbage bags. Tie off the top of the bag and step on the cobs until they are crushed. Repeat this process until finished.
Take the crushed cobs and mix with a binder. Binders can be from flour and water or even cassava corn porridge. Mix the crushed coal and the binder in a bucket until an even consistency is reached; about the thickness of bread dough.
Place the mixture in a briquetter. There are different types of briquetters ranging from very simple hand made tools to industrial quality, but they all work under the same premise. Put the mixture in, squeeze it tightly with a press to bind it and then remove the now fashioned briquette. Place the briquettes out to dry.
