48 ELEMENTARY WOODWORKING 



A drawing which is made the exact size of the object 

 represented is known as a full-sized drawing ; but for 

 large objects such a method would necessitate large and 

 unhandy sheets of drawing paper. It is customary in 

 such cases to make what is called a scale di'awing. 



A scale drawing may be half, quarter, or eighth size, 

 and the fact is printed under the title in smaller letters, 

 thus : I- inch = 1 inch, or ^ inch = 1 inch. 



Other scales may be used. In map making, for ex- 

 ample, a sixteenth of an inch may represent one, ten, 

 or even a hundred miles. Wliatever scale is used, how- 

 ever, the dimensions must always give the exact size of 

 the object represented.
