418 THE YOUNG FARMER'S MANUAL. 



swedged set. Bent set is used for both crosscut and slitting-saws ; 

 but swedged set is used only for saws that cut lengthways of the 

 grain. There are two kinds of lent set, but we shall notice but 

 one in this work. 



630. The least possible amount of set, in either a crosscut or 

 ripping-saw, and have the saw work easily, is the best. The 

 greater the amount of set the wider will be the kerf; and the 

 wider the kerf the greater must be the power to drive a saw. 

 Soft wood requires more set than hard wood. A good saw often 

 does bad work in consequence of too much set. If there is too 

 much set, a saw will sometimes run in consequence of it ; and 

 sometimes, especially if the feed is heavy, if there is too much 

 set, a saw will often make a rough and jagged cut, which makes 

 a saw run hard. 



631. The rudest and simplest mode of setting a saw is, to lay 

 the blade of it on a smooth end of a block of hard wood, and with 

 a punch and hammer bend the point of every other tooth by a 

 single blow, and then turn the saw over and set the other side, 

 being careful to place the punch on each tooth in the same place, 

 and to gauge the force of each blow as nearly as may be. If the 

 FIGS. 178 179. P uncn * s placed near the points of some teeth 



and near the roots of others, the teeth will be 

 set very unevenly. Two or three teeth on each 

 side should be set near the end of the saw first; 

 and then, if there appears to be too little or too 

 much set in these teeth, let the blows be lighter 

 or heavier, as may be necessary. 



632. Fig. 178 represents an edge-view of a 

 slitting-saw having the teeth set by bending the 

 points. 



633. Fig. 179 is an edge- view of a slitting- 

 saw having the teeth set, or spread, by swedging. 

 It is not practicable to set small saws by swedg
