Very frequently the arrises of a board are removed; the result produced is known as a chamfer. Chamfers are laid out with a pencil rather than gage and try-square and knife. While the latter is more accurate the V-shaped grooves produced, spoil the appearance of the piece after the chamfering is completed to the lines. Hold the pencil as in Fig. 60, first having measured the required distance the chamfer is to be laid out from the arris. This method of laying out a chamfer is known as pencil gaging. The lines will be laid off on edges, on ends, and on the surface at the two edges and two ends where the chamfer is to be placed, entirely around the piece of stock.

Holding the plane as in Fig. 61 plane the two arrises extending along the grain. Next, holding the plane as in Fig. 62, but moving it in a horizontal direction, plane the two end chamfers. By holding the plane as indicated in Fig. 62 a shearing cut is secured which, with the buttressed effect produced by planing the edge chamfers first, makes it possible to plane entirely across the end without splitting the far corner. In all cases where a plane is turned across the stock so as to secure a shearing cut, the plane should not be turned so far that the benefit of its length is lost as an aid to producing a straight surface.

As a rule, the eye will detect inaccuracies in a chamfer. If a further test is desired, Fig. 63 illustrates one.
