[Illustration: Fig.103.The Order of Planing a Board.] In a word, the order to be followed is graphically represented in H, Fig.103.The surfaces are numbered consecutively in the order in which they are to be planed.
The advantages of this order are these: by planing the working face first, a broad surface is secured to which the others may be made true.
