QUARTER SAWING. 



169 



Quarter-sawed lumber presents a more durable surface and 

 warps and shrinks less than that tangentially sawed. If these 

 points alone are the chief considerations, any wood is considered 

 quarter-sawed that presents the edge of its annual rings to its 

 surface at an angle of not less than forty-five degrees. This is 

 done in various ways. 



Figure 44 illustrates one method of quarter sawing such 

 woods as Yellow Pine, which are so sawed solely to increase 

 their strength arid wearing qualities. Slabs are taken off the 

 four sides, then a cant A. B. is removed by cutting to within two 

 or three inches of the heart. This cant is thrown back on the 

 deck. Then the mill goes on sawing right through the heart C., 

 taking off four to six boards, as the case may be, which are run

through the edger and have the heart cut out. This leaves two 

 cants of the same thickness. The one on the deck A. B. is put 

 back on top of the one D. E. on the carriage and both are cut 

 up together. Practically all of the stock thus made, except the 

 boards taken off in slabbing, is edged grained, and if oak about 

 half of it would show a fair figure. 



If Quarter Sawing is Done for the Purpose of Bring- 

 ing out the Silver Grain of the wood, as is necessary in the 

 case of White Oak for best effects, then the saw cut should 

 always be made towards the heart and on the line of the silver 

 rays. This is a much more wasteful process than the former
