A thin sizing coat of glue should be applied to close the endgrain pores. For light frames, pictureframe nails, in addition to the final glue coat, will suffice. Waxed paper should be placed under the joints before the jig is glued and clamped in. In heavier frames, corrugated fasteners driven into the rear can be used, provided the molding is thick enough. Dowels are necessary reinforcements for heavy frames, and slip feathers or splines of veneer (Figure 2.8) have great holding power. Grooves for the latter type of joint consist of a saw kerf through both members when they are clamped together as shown. The grain of the feather or spline should be at right angles to the miter cuts. Finishes. The finish of the frame depends on the kind of wood employed, the color scheme of the room, and most of all, the picture itself. If a clash with other hues can be avoided, an interesting treatment is to select a dominant color or shade in the picture as the principal color for the frame. When the frame is beaded, an inner band of silver or aluminum paint is another pleasing variation suitable for many framings. Gilt, bronze, and silver paints are standard finishes. ThreeDimensional Effects. When duplicate pictures or photographs are available, interesting depth effects can be obtained bv the use of an additional sheet of glass. First a piece of glass the same size as that already cut for the fran Feather of Veneer iг SawSerf Fig. 2.8. INDOOR FURNITURE CONSTRUCTION is laid over the picture and its mat, as it will appear in the frame. Then central, foreground part of the picture is cut out and pasted on the second g sheet directly over the same figure in the glasscovered picture. All that rem, is to cut the rabbet in the back of the frame deep enough to receive both pit of glass, the mat, picture, and backing, as in Figure 2.9.

Even deeper relief can be secured from three identical pictures, with objei in the intermediate background cut out and cemented intheir proper positio on a third piece of glass, midway between the other two. Trays. Heavy frames holding triplestrength window glass make excelle serving trays when backed by light, feltcovered plywood that has been glued ai bradded, or screwed, to cover the entire back of the frame. The best practice to cut a second rabbet to the depth of the plywood, 4 in. inside the outer edj of the frame. A picture, design, or piece of colorful fabric can be inserted betwe the glass and the backing, and simple handles screwed into the ends. plywood projects Plywood panels, made up of thin layers of wood glued together with the grai of one at an angle (as much as 900) from the other, have proved a boon to cabine makers. Fabricated with one or both sides veneered with a wide selection с beautifully grained woods, these panels vary in total thicknesses from less tha Aq in.
