—The old-fashioned wooden planes are still preferred by some woodworkers. The iron bodied planes have displaced them because of the ease with which they can be adjusted rather than because they produce any better results. Wooden planes are subject to warpage and as the bottoms become uneven thru wear, it is necessary to straighten and level them occasionally. The plane-iron and cap-iron of the wooden plane are fastened in the throat of the plane by means of a wooden wedge. This wedge is driven in place with the hammer. [Fig. 54] shows the manner of holding the plane while setting the irons and wedge. If the plane-iron does not project enough, the iron is lightly tapped as indicated. If too much projects, the stock is tapped as in [Fig. 55]. This figure also illustrates the manner of removing the wedge, two or three blows being sufficient to release it so that it can be withdrawn with the hand. In setting the plane-iron, should either corner project more than the other, tap the side of the iron.

[Fig. 56] shows the manner of holding the smooth plane in releasing the wedge, as well as when the cutting edge projects too much.
26. Planing First Surface True.
—A true surface is one which is straight as to its length and width and which has its surface at the four corners in the same plane. Select for this first surface, which we shall call the face side, the better of the two broad surfaces. Knots, sap, wind, shakes, etc., should there be any, must be taken into account when passing judgment. Often the two sides are so nearly alike that there is little reason for choice.
