Building a coal forge is very easy. Really a coal forge can be built out of anything as long as air can be forced under or on the side of the fire to elevate the heat. these plans make a real nice permenent table forge, ( the kind found in most old time blacksmith shops) if you want to make this forge portable make the table a little shorter and out of a lighter material. you can also make a protable forge out of a charcoal grill as seen below. if you don't have a hand cranked blower a vaccuume cleaner on reverse works fine but very noisy! if coal is not redialy availible to you don't worry. charcoal can be used instead.
