35. Boring Holes for Rope. With marking gage, make 

 a short, light center line on face side of board from each end 

 thru a point 3" from each end (Fig. 63). By the use of the 

 try-square and knife, cross each of these center lines with a 

 short knife line at right angles to the joint edge (Fig. 64). 



With 3/4" auger-bit and brace, bore the two holes for the 

 rope, as shown in Fig. 65. A piece of board must be placed 

 on the back of the swing board, opposite the auger-bit, to pre- 

 vent splintering the fibers of the wood in the swing board, or,

soon as the spur protrudes on the back side of the swing 



board so that the hole may be finished from the opposite side. 



36. Sawing End Notches. On each end, measure 1" in 



each direction of the center 

 lines, square across the ends 

 at these points and on the face 

 side join the end of each of 

 these lines with the corre- 

 sponding side of the hole, to 

 form tangents (Fig. 66). 



Place the board in the vise 

 so that one of these lines is in
