one side of the saw, and to file the other side when standing on 

 the opposite side. The same rules hold good for filing circular 

 saws that are observed for filing long saws. A circular saw for 

 cutting across the grain should have not less than four t^eth 

 one on each side of the saw filed square across, and a little 

 shorter than the others, to cut out the chip. These teeth should 

 have a good hook. All the teeth should be kept as nearly of a 

 size and length as possible ; and for this purpose the templet 

 (see Fig. 184) should be placed on every tooth before it is filed, 

 in order to show whether or not a tooth has the desired shape. 

 It is sometimes a very good practice in filing any kind of saw, 

 and especially if it is a very soft saw, to go over all the teeth 

 with a very fine file, or with one that is nearly worn out, after 

 they have been brought to an edge with a sharp file. This pro 

 cess gives the teeth a more perfect edge. A good fine edge can 

 never be obtained with a coarse file, if the strokes be made ever 

 so light. The finishing strokes with the file should always be 

 made from you, and if the teeth be fleam-pointed, the strokes of 

 the file should be made in the same direction that the teeth are 

 bent in setting. My twenty-four-inch circular saw, for cutting 

 fire-wood, with teeth an inch and one-fourth apart, is filed fleaming, 

 at an angle of about forty-five degrees ; and every fifth tooth is 

 filed square, and a sixteenth of an inch shorter than the others ; 

 and I have never met with a saw before which will run through 

 large knots and gnarls so noiselessly, and with so little power, and 

 cut so neatly. , 



654. There are several styles of saw-filers for filing circular 

 saws. But a man should have more saws to file than a common 

 farmer usually owns, in order " to make it pay " to purchase a 

 filer, which costs from $10 to $15. A little practice and skill 

 are more important than a saw-filer, unless some cheaper article 

 shall be invented than any with which I have ever met.
