Figure 3-78. Various types of joints that can be used on box corners. Which you choose depends on how the project must appear. The mitered joint is the neatest, but is not much stronger than a butt unless you reinforce it with a spline.
Joints are used to hold parts together. The joints can be simple or advanced, but all must be carefully cut if they are to look good and hold with maximum strength. Figures 3-78 through 3-81 illustrate some joint applications on typical woodworking projects.

Figure 3-81. Drawer supports, or rail frames, are integral parts of case construction. Some typical assembly methods are shown here. Many rail frames are done with thin inset plywood panels so they serve as dust guards between drawer sections. Click on image to see larger view.
