In [Fig. 2729], for example, it is seen that if a right angle be laid in a semicircle so that its sides meet the corners of the same when revolved, its corner will describe a true circle; hence at each plane stroke the plane may be slightly revolved, to put on the cut, which must be very light, as the core box plane is only suitable for finishing purposes. For planing across the end grain of wood, what are termed block planes are used, the angle of the blade to the sole being from 65 to 85 degrees, as shown in [Fig. 2730], which represents the Stanley iron frame block plane. In block planes the bevel that is ground to sharpen the blade is placed in front and therefore meets the shaving instead of the flat face as in other planes.

Fig. 2732.
[Fig. 2731] represents the Stanley bull-nose rabbet plane for getting close into corners, and [Fig. 2732], a block plane, in which the blade may be set in the usual position or at one end of the stock as denoted by the dotted lines.
