Firewood has to be split into pieces and dried before it can be burned. Stacking green wood is the most efficient way to dry it. Building a storage rack that allows the wood to be kept up off the ground is preferable to leaving the pieces in a pile on the ground. A cord of wood is measured 8 feet long, 4 feet high and 1 foot deep. Whether the wood is green or dried, a rack built to hold a cord of wood is the best way to store it.
Cut two of the 8-foot boards in half, making four 4-foot pieces.
Cut the 6-foot board into six 1-foot pieces.
Lay the remaining two 8-foot boards parallel to each other, 2-inch sides up, and 12 inches apart.
Set one of the 1-foot pieces, 2-inch side up, against the ends of the two 8-foot boards. Flush the ends square, forming a 90-degree angle on each side. Drive three nails through the 1-foot piece into each end of the 8-foot boards.
Nail a 1-foot piece to the opposite end of the 8-foot boards, forming an enclosed rectangle.
Stand one of the 4-foot pieces vertically in an inside corner of the rectangle. Flush the vertical piece into the corner with the 4-inch side against the 8-foot board and the 2-inch side against the end board. From the outside of the rectangle drive four nails through the 8-foot and vertical boards; bend the nail points over to lock the two boards together.
Attach the other three 4-foot pieces to the remaining corners of the rectangle in the same manner as the first board.
Hold a 1-foot piece, 2-inch side up, 3 inches above the 1-foot piece that forms the end of the rectangle. Flush the ends of the second 1-foot piece even with the sides of the two vertical boards and drive two nails through each end of the 1-foot piece and into the vertical boards.
Place a third 1-foot piece 3 inches above the second 1-foot piece and nail it in place the same way.
Nail the last two 1-foot pieces to the opposite end of the structure in the same manner.
