Woodworking Uses of Tools

on a twisted string, communicated to the saw blade by a 

 wooden lever frame. 



All our saws cut in one direction only away from the 

 operator ; consequently, in sawing, the power should be given 

 on the forward stroke, and care should be taken to keep the 

 direction of the saw constant. It is well to remember that 

 the arm and elbow should be in the plane of the cut to be 

 made in order to secure a straight cut. It should be remem- 

 bered also that the track of a saw cut is usually twice the 

 width of the saw thickness. 



Hammers. Several kinds of hammer are in common 

 use, either of those shown in Fig. 3 being recommended (see

also metalwork tools). Little need be said upon this, beyond 



pointing out that if one can use heavy tools comfortably they 



will do more work, provided they are used 



correctly. It is a common source of annoy- p-| (A) 



ance to be obliged to do a heavy job with a 



light tool. The hammer head is meant to be 



controlled by the handle, not to be pushed at 



its work by the handle, consequently it should 



be held well away from the head, and allowed 



to do its work by the momentum it acquires in 



the swing towards the work. 



The same remark applies to the mallet, used 

 for striking tools or pieces of work which the 

 hammer would injure. The best shape is that 

 sketched, as the angle of the handle end (A) 

 (Fig. 4) prevents the head becoming loose or 

 displaced. Mallet heads fastened on by a 

 wedge of wood should be refused. The faces of the mallet
