MEASUREMENT AND GRADING OF OTHER PRIMARY PRODUCTS 



Hickory is used for the manufacture of many specialty items such as 

 skis, Softball bats, and sucker rods (1). Specifications vary from industry 

 to industry and from one manufacturer to another within a given industry, so 



that it is almost impossible to set

down standards. The handle indus- 

 try, however, has grades and spec- 

 ifications that permit generalization. 



Handle Blocks and Blanks 



Hickory handle blocks are com- 

 monly bought and sold on the basis of 

 the handle "count" for various diam- 

 eters (fig. 1). Sometimes bolts are 

 measured by the standard cord of 128 

 cubic feet. A pile 4 feet high by 10 

 feet long of 40- inch handle bolts equals 

 one cord, approximately. Table 14 

 shows the number of handles obtainable 

 from blocks of different diameters.
