PATTERN MAKING 



19 



plane has the advantage of being so constructed as to be held 

 easily in one hand. Owing to the low angle at which the cutter 



is placed it works more smoothly 

 and easily on end wood and on 

 miters than any other plane. 

 In cases where lumber must 

 be dressed from the rough, 

 without being first roughly 





dressed in a planing mill, the 

 No. 40 scrub plane, illustrated 

 in Fig. 28, will be almost indispensable. It is 9^ inches long, and 

 has a cutter 1^ inches wide. The cutter is a single iron, and is 

 ground and sharpened very rounding on the cutting edge, as shown 

 in Fig. 28, to allow of cutting 

 a very thick shaving without 

 grooving at the edges. This 

 plane works rapidly and easily, 

 preparing the rough-sawn sur- 

 faces of planks for the finish- 

 ing planes. Fig. 28. 



For truing and smoothing circular arcs and curves of all kinds, 

 either convex or concave, there is no tool that equals the circular 

 plane, illustrated in Fig. 29. This plane has a flexible steel face

which can easily be shaped to any required arc or curve by turning 

 the knob on the front of the plane. 



The Rabbet Plane. Among the special planes used by the 

 pattern maker, the rabbet plane, illustrated in Fig. 30, is the most 

 important. The face of this plane is always flat and at right angles 

 to the sides. It is used in working out square angles and corners,
