ting (Fig. 54). Finally, raise the hands, slightly continuing 

 this motion. This will tend to create a whetted bevel made 

 slightly at an angle with the ground bevel (Fig. 55). The 

 plane-iron should be held in this position for a few moments 

 only, when it may be reversed, laid flat on the top of the stone 

 and given a few circular strokes (Fig. 56) .

 edge for jack plane. 



The irons for all planes except the jack should be ground at 



right angles with the edge, with the corners rounded (Fig. 57). 



The plane-iron for the jack plane, if used principally as a 



roughing plane, should be ground rounding on the edge as in 



Fig. 58. When used 

 as the only plane in a 

 kit, it should be ground 

 very slightly rounding,

 a plane is used exclu-

wood, should be ap-

27. Care of Plane. In order to protect the edge of the 

 plane-iron, lay the plane on its side when not in use. Fig. 7
