Abstract
This invention is directed to an apparatus and method for making a shingle from a block of wood. The block of wood is canted and a shingle is sawed from this block of wood. The shingle has a thick end and a thin end. After the shingle has been sawed, the block of wood is moved away from the saw and canted at a new angle with respect to the saw. Then, the block of wood is moved toward the saw and another shingle is sawed. This process is repeated to form shingles from a block of wood.
