46. Rough Cutting. If necessary, rip the pieces for the 

 sides of the box from a board, and square and saw each to the 

 required length. Plane each board to width (3-1/2") and 

 thickness (3/4").

 ing out joint. 



47. Laying Out. On the face side of each board, which 

 should become the inside surface of a side of the box, square a 

 knife line 1" from each end, or a distance equal to the thick- 

 ness of the stock. Continue this as a fine pencil line around 

 the piece.

 marked for removal. 



From the joint edge, which should become the upper edge 

 of a side of the box, gage consecutively on the end and on both 

 surfaces of each end of each board a line 3/4" from the joint 

 edge to form the first dovetail line (Fig. 94). Reset the gage 

 to 1-3/8" (3/4" + 5/8"), and in a similar manner gage the sec- 

 ond dovetail line on each end of each piece (Fig. 95) . Contin- 

 ue this process of gaging, adding 3/4" and 5/8" alternately 

 until all cuts are indicated. On the end of each board, mark 

 with a pencil the parts of the joint to be removed (Fig. 96). 



48. Sawing. Saw with the rip-saw to each line in the
