Rh its fence is adjustable to the face, allowing a rebate to be made of any width within the breadth of the plane iron. These planes,



and also the plough (Fig. 76), are principally used for grooving with the grain. They are not used so much as formerly, owing to the introduction of machinery in large



shops, but they are still indispensable to most joiners. For the working of hardwoods, to obtain perfect joints, gun-metal or iron planes known as the shoulder plane and bullnose plane are considered indispensable, as is also the steel smoothing



plane which is used for cleaning up face work. The router, or "old woman’s tooth" (Fig. 77), is used for working out the bottoms of rectangular cavities; the chariot plane (almost obsolete), is used for the small parts of work which the smoothing



plane cannot get at, and for planing end grain and cross-grain work ; chamfer planes are used for taking off sharp edges to form chamfers; mitre shooting planes



are sufficiently described by their name; and the plough or plough plane (Fig. 76), used for cutting or "ploughing" grooves. There are many other varieties of planes; the names and uses of the more important



will be treated upon in some of the following sections. Particulars of these may be found readily by reference to the index.
