PATTERN MAKING 



For very accurate work, an excellent tool of this kind is 

 illustrated in Fig. 62. The beams furnished are 4 inches and 



13 inches in length. By the use 

 of the cone center, shown at V, 

 which maybe substituted for the 

 regular point, the tool can be 

 used for scribing a line around 

 any hole already bored which 

 is sometimes a matter of great 

 convenience. The complete set 

 includes the pen, pencil, straight 

 and bent points, and the cone 

 center, as-shown in the cut. 



CALIPERS. 



Calipers, like dividers, are

with and without screw adjustment. Fig. 63 illustrates the screw-
