Use the diagrams to measure where the stiles start and stop on the feet. Like the rails, use the edge of the stiles' tenons like rulers to mark the beginning and end of each mortise. When cutting the shelves' notches, draw a line on your table saw's fence to determine when to stop cutting. Because of the table saw's curved blade, more material will be cut away on the underside of the piece than on the top. Wedges slide through mortised holes in both the top and bottom shelves. Use the diagrams to lay out the locations of the V2" x V2" mortises. Note on the diagram how the mortises are located V8" behind the line of the rails. Sturdy Shelves With the sides now assembled, it's time to cut the shelves. First you need to cut notches in the shelves' corners. The top and bottom shelves' notches are 21/4" long by 3/4" wide, allowing enough overhang for the wedges. The notches in the two middles shelves are 3/4" long by 3/4" wide. Once you've measured and drawn where the notches start and stop, head to the table saw to cut the notches on the top and bottom shelves. Because the table saw's blade is curved and because you won't be running the entire length of the board through the blade, you must be a little creative in your cutting. First, correctly position your fence and raise your blade to its appropriate height. Then, with a grease pencil, draw a line on the fence where the blade enters the table. Now, draw a line on your work where the cut should stop. Run the piece through until the two lines meet, stop and pull the piece back. Carry the line on the piece over to the other side, flip the shelf over and again run it through until the two lines meet, as shown in the top photo. Head to your band saw and cut the remaining part of the top and bottom shelves' notches away. Now cut the notches on the middle shelves, using the band saw. The whole bookcase is held together tightly by tapered wedges that snug into through-mortises in the top and bottom shelves. Cut the mortises in the top and bottom shelves, as shown at left. Tapered Wedges If you haven't done so already, plane the stock for your wedges down to 1/2" thick. Measure and make a mark 3/8" from the top of each wedge, and another mark 3/8" wide from the bottom of each wedge. Draw a line, connecting 58 Popular Woodworking August 2003 |
