(The boring is done with the brace, [Fig. 103], and the bit, [Fig. 104]. Bits are of different forms; [Fig. 105] shows a number of different styles).
It will be necessary only to draw the lines across the end of the piece marked [B, Fig. 102], as the marking of this piece for the recesses will be made by holding in position the piece already cut, and scribing or marking the pins or tenons, then squaring the lines across the end.
Great care must be taken in sawing the mortises if a perfect fit is desired. This can be done only by sawing on the inside of the line, cutting the lines in two. The pieces should go together by light driving, and should be perfectly square on the inside. If the joint is satisfactory take apart and glue together. After the glue is dry the joint can be smoothed and the ends of the pieces cut off and squared to the proper dimensions given in [Fig. 101].

EXERCISE NUMBER 8.
DOOR FRAME FOR GLASS PANEL.
The preceding exercises are only a few of the methods employed by the workmen in joining pieces together. The experience gained in their execution will be of great help in the work that follows.
[Fig. 106] shows the working drawing for a small frame door for a glass panel; the details and sections of the pieces required are shown in [Fig. 107].
It must be taken into consideration that this door is actually to fit into an opening of a given size, and a little forethought will be necessary to work the material so that when all cutting and fitting is done the correct size will be the result of the labor expended.
