Fig. 101.
In [Fig. 101] is given the working drawing of the common dovetail, and [Fig. 102, A-B] shows the details of each piece.
The stock can be prepared in one piece (having it long enough so that if a poor joining is made, the dovetails can be cut off and new ones cut on this piece). After planing, cut in two, square one end of each piece (the ends to be joined). To lay out the work, it is advisable to lay out the piece with the pins or tenons first. From the squared end measure in the thickness of the side; then mark on both sides, using the knife to draw the lines.
Fig. 102.
On the face side (which is the side that would be toward the inside of a box) lay off the lines shown for the pins in the detail marked A, [Fig. 102]. These lines can be drawn from the working edge with a gauge, or, if the ends are perfectly square, the square can be used (the lines being parallel with the edge). From these lines will be drawn the oblique lines across the end with the bevel set at a taper of 1 inch to 4 inches. The bevel can be set by the steel framing square, by the methods already given.
After drawing the lines saw down the required depth on the outside of the line, and remove the pieces between the pins or tenons by first boring a hole through the piece to be removed, then cutting from both sides with the chisel.
