with a view to make a saw cut faster. Suppose, for instance, 

 that we cut away four-fifths of the teeth, how fast will a saw 

 cut ? For sawing timber of ordinary size, the teeth should not 

 be more than one inch apart. When a saw jumps and jerks 

 along, it is very certain evidence that the teeth are too far apart. 

 The smaller in diameter the timber is, the closer together the 

 teeth should be, in order to work best and smoothest. As the 

 teeth of two-hand crosscut saws are filed without any hook, they 

 should be filed rather slim and narrow at the base or roots, in 

 order to cut the fastest. 



643. Improved two-hand crosscut saws are now manufactured 

 with every third tooth formed like a cat's claw, and filed square 

 across, and about a sixteenth of an inch shorter than the others* 

 which are filed very fleaming. They are much superior to the 

 common kind of saws. 



PUTTING TWO-HAND CROSSCUT SAWS IN ORDER. 



644. Dress out two strips of board, with one edge of each one 

 of the same circle as the cutting edge of the saw, and screw 

 them together with the saw between them, like Fig. 182, which 

 shows a combined clamp and jointer, with the longest teeth of a 

 saw extending above the edges of the clamp. The screws are

put between the teeth. Adjust the clamp so that the long teeth 

 will extend a little above the edge, and with a file dress them 

 off even with the edge of the clamp. After it is jointed take 

 out the screws, and place the saw in the bench-vise, and file it. 

 645. In filing, always endeavor to file the spaces as deep or
