or the
drawer bottom should be cut or at least laid out before laying out the
joint. See also drawers, p. 190, and Fig. 287, p. 191. On the end of
the drawer front, gage the depth of the joint. Gage the same distance
on both broad surfaces of the drawer sides, marking from the front
ends. Lay out and cut the dovetails as in a thru dovetail joint,
taking especial care to have the groove for the bottom completely
within the lower tail. Take care also to make the sides, one right and
one left, not both alike, so that the groove will come inside. Lay out
the drawer front by superposing the dovetailed side, X, on the end of
the front, Y, as in a thru dovetail. Saw and chisel out the mortises
and fit together.
_No. 50. A stopped lap dovetail_, Fig. 267, is one in which neither
the tails nor the pins extend thru the other members. Hence the joint
is concealed. The lap may be rounded. It is used in fine boxes, trays,
etc.
_No. 51. The blind miter or secret dovetail_, Fig. 267, is a joint in
which only part, say one-half, of both boards is dovetailed, the outer
portion being mitered. The edges of the boards are also mitered right
thru for a short distance so that when finished the dovetails are
invisible. It is used in highly finished boxes.
BEVELED JOINTS
A beveled joint is made by beveling the members so that the plane of
the joint bisects the angle at which the members meet. This is called
the "miter" and may be 45 degrees or any other angle. It is a neat but
weak joint unless reinforced by a spline, nails, or in some other way.
[Illustration: Fig. 253. Gluing Together a Picture-Frame (See also
Fig. 254.)]
_No. 52. A plain miter_, Fig. 268, is a joint where the beveled edges
or ends abut and are simply glued or nailed together. It is commonly
used in picture-frames, inside trim, columns, boxes, and taborets,
four or more sided.
[Illustration: Fig. 254. Picture-Frame-Clamp.]
For gluing mitered frames, the most convenient way is with the aid of
the picture-frame-vise, Fig. 172, p. 101. Nails are driven or splines
inserted as soon as each joint is glued. Where this vise is not
available, an ordinary metalworking vise may be used, as follows:
Fasten one member, X, face side up, firmly in the vise. Bore holes in
the other member, Y, at the proper places for the nails. Insert nails
in the holes, apply the glue to both mitered surfaces, place the glued
surfaces together, letting Y project about 1/8" beyond X. A
