What different tasks can the jointer do?

A jointer is primarily used to create flat surfaces on rough lumber, ensuring one face and one edge are straight and true. It can also be used to square edges for joining two pieces of wood together and to remove warps and twists in the wood. Additionally, with proper technique, a jointer can be used for beveling edges and creating tapered cuts. Overall, it enhances the accuracy and quality of wood preparation for various woodworking projects.
