PATTERN MAKLMi 



Take any block of wood from 12 inches to 16 inches long, about 2 inches 

 wide, and about l,^ inches in thickness. With try -square and a sharp-pointed 

 pocketknife, lay it out as illustrated in Fig. 19, on the upper, front, and back 

 sides of the block. The knife-cuts must be at least ^ inch deep, and about 

 J^ inch distant from each other. Next proceed to saw up the block into thin 

 sections, sawing each time so that the saw kerf will be just outside of, but 

 close to the knife line, as indicated at <t. 



The saw-cut through the block should be true to each of the three lines; 

 and while the saw passes along one side of the line, its teeth should not 

 scratch the opposite side of the knife-cut, but should leave a smooth, clean 

 angle of the knife-cut on the block, as shown at b in Fig. 19, while at the same 

 time it should be so close to the line as to leave no wood to be smoothed off 

 with plane or chisel.

A few hours' thorough and careful practice of this exercise 

 will enable any one to use the saw successfully. 



Compass Saw. As the work of the compass saw, illustrated in 

 Fig. 20, will be both with and across the grain of the wood, the 

 best form of tooth will be that shown in Fig. 21, having more pitch, 

 and slightly less bevel, than the crosscut saw. A crosscut saw 



will rip better than a rip saw will cross- 

 cut; hence the shape of tooth should 

 be between the two. Compass saws 

 are ground very thin on the back of the 

 blade, but in order to turn easily they

on the beginner the necessity of keeping his K;I\V 



other cutting tools perfectly sharp and in good working condition 



at all times. A sharp saw w r ill work faster, and will always do 



smoother and better work with less set and with less expenditure 



of power, than a dull one. Even to saw well is an art, which 



cannot be gained through the use of dull, imperfectly set, and 



poorly kept tools. To file well will require from the beginner close 



attention, a study of the subject, and c{>ful practice, all of which
