Bore the hole in the upright which will receive the dowel that connects the frame to the upright. for a biscuit. Dowels, however, will increase the strength of a joint and can be used in relatively small areas. A set of dowel and tenon centers makes the construction of accurate dowel joints almost foolproof. They are inexpensive, use no electricity and are easy to use. Drill the hole for the dowel in the workpiece, insert the correct size dowel center, and press or lightly tap the end to mark the piece to be joined. The point in the center will mark the exact location for the hole. Drill the hole and you are ready for the dowel. As you put the shelf together, you will need to drill the dowel holes. First drill the 3/8" dowel holes in the notch on the outside edge of each upright (see Fig. 8). Use a dowel point to locate the hole in the end frame. The upright should be flush with the back end of the end frame. Glue the uprights to the frame ends, making sure they are square (see Fig. 9). It's now time to dry fit the support (E) and the front frame to the glued-up ends. You should drill the dowel holes in the front ends of each support. With the support clamped in place, install a dowel point and mark the location for the dowel in the front frame (see Fig. 10). Now glue the support to the end frames and the bracket into the groove and against the frame end. Finally cut the dowel to fit, glue, and clamp the front frame on each end frame and support. The wall bracket frame is now ready for the telephone center; you can now sand, finish to match and mount it to the wall. Make sure it is firmly attached. If you are going to modify this design for a shelf, you will need to shorten the length of the end frames and supports by 4-1/4" each. This will provide you with a 9" deep heavy-duty shelf. Cut a piece of 1/2" plywood to fit into the frame. After cutting to fit, use a straight bit in your router table to cut a I /4" deep rabbet in the three outside edges so the plywood will fit flush with the top of the frame.
