Rolltop Details
The upper and lower back panels are constructed very similar, the only difference being in the height. The inside edge of the 3-in. pieces is plowed with a 1/4-in. plow 3/8 in. deep exactly in the center and also both edges of each 2-in. piece. The 16-in. pieces in the upper back panel and the 24-in. pieces in the lower back panel must be cut 1/2 in. longer and a 1/4-in. tongue made on each end to fit into the plowed groove and form a mortise joint.
The upper back panel is filled in with four boards 9-1/2 in. wide and 16-1/2 in. long, while the four boards in the lower back panel are 9-1/2 in. wide and 24-1/2 in. long cut from the 1/4-in. hard wood. When the grooves are cut properly, the joints made perfect and the boards fitted to the right size, these two panels can be assembled and pressed together in cabinet clamps. This will make the outside dimensions as given in the drawing.
The end panels are made very similar to the lower back panel, the only difference being in the width of the filling boards, which are 10-1/2 in. for the outside end panels and 10 in. for the inside panels. One end panel and one inside panel make the sides of one pedestal. As the end panels are 1 in. wider than the inside panels they overlap the back panel and cover up the rough ends of the boards. A 1-in. piece 2 in. wide is fastened at the top and bottom of each end and inside panels as shown by the dotted lines. The lower back panel is fastened on by turning screws through the back and into the ends of these pieces. The bottom pieces have 2-in. notches cut out, as shown, into which to fit two crosspieces across the bottom of the pedestal for holding the casters. The top end panels are made as shown in the drawing, the inside edge of the pieces being plowed out, making a groove the same size as in the other pieces of the panels. The panel board is cut to the proper shape from the 1/4-by 24-in. material. The length given in the material list will be sufficient if the pointed ends are allowed to pass each other when laying out the design.
Details
Instead of cutting a groove for the roll top curtain, one is made by fastening a 1/2-by 3/4-in. strip 7/8 in. down from the edge and on the inside of the panel. A thin 1/4-by 1-3/4-in. strip is bent to form the shape of the edge and fastened with round-headed brass screws. A 1-in. piece is fastened at the back and a groove cut into it as shown by the dotted line into which to slide a 1/4-in. back board. The top is a 12-in. board 54 in. long.
