11. Rip-sawing. The chief tool exercise in this project 

 is rip-sawing. It is more difficult to make a series of parallel 

 rip-saw cuts than to make an individual one. In this pro j ec t, 

 the cuts must be made with great care, that one fan strip may 

 not be weakened more than another. The guide lines must 

 be followed accurately. 



' There is a possible element of

difficulty in sawing each edge of 

 the trellis stock to a taper. The 

 saw must run at an angle with 

 the grain. The piece should be

ing for Length. Select the 



best surface (1) and the best edge (2), as in Fig, 19. With the 

 try-square blade on one face, called the face side, and its 

 beam on one edge, called the joint edge, square a line across 

 the face side near one end (Fig. 19). 



With the beam of the try-square on the face side and the 

 blade on the joint edge, run the try-square with the left hand 

 toward the end of the line squared across the face side until 

 the blade touches the blade of the knife held in the right 

 hand, the point of the knife-blade being on the end of this
