After spending years working around wood, Woodworth would design and then patent the Woodworth Planing Machine in 1828. [2] Hailed as the greatest improvement to the planing machine so far and one of the most important inventions of the century, it added speed and efficiency to the process of creating lumber for domestic usage.
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece. [1] A planer is similar to a shaper , but larger, and with workpiece moving, whereas in a shaper the cutting tool moves.

Obtaining the first flat side requires either face planing with a jointer or face planing using a planer and jointer sled.
