With the sides, shelves and top created, work can begin on assembly of the case and shaping the cove-molding for the base.
Materials: Table saw
Table router
Band saw
Chop saw
Biscuit joiner
Goose-neck scraper
220-grit sandpaper
Slow-setting plastic-resin glue
Safety glasses or goggles
Note: Cut sizes may vary. For exact measurements, please contact David Marks through his Web site -- information below under Resources. Safety Alert: Always wear safety goggles or safety glasses when working with wood, power-tools, saws, drills, routers, etc.
Top Piece and Case Assembly
Molded Base With the case assembled, work can begin on the cove-molded trim that will wrap around the base. For this piece, the molded trim was made using the table saw. - We began with a piece of stock 1-1/2 inches thick, 5-1/2 inches wide and 28 inches long. This single piece will produce enough shaped trim to wrap around the base of the bookcase. The trim will be miter-cut for a perfect fit.
- The first step is to cut a 4-3/4-inch-wide cove centered in the stock. To do this, create an angled fence by clamping a jointed board to bed of the table saw as shown (figure F). Folded pieces of sandpaper tucked under the board will help keep it from slipping.
- It's advisable to make test-cuts on a piece of scrap-wood to confirm that the fence is set at the appropriate angle. The objective is to make a cove cut centered exactly in the board (figure G).
- With the angle properly set, cut the cove in the jatoba in multiple passes. After making the first pass (figure H), raise the blade 1/16-inch and repeat the pass. Repeat this process until the cove-cut is complete.
- Once the cut is made, use a gooseneck scraper (figure I) and some 220-grit sandpaper to smooth and refine the shape of the cove.
- Once the curve is smooth, use the band-saw to rip the stock in half (figure J). This provides the cove-molding stock needed for the base.
- Use the chop saw, and set the angle of the miter-gauge to 45-degrees, to cut to rough size the three pieces that will be needed to attach to the base of the bookcase.
- Biscuit joinery is used to join the miter-cut pieces together. Use the biscuit joiner to cut number-zero biscuit slots in the angled ends. The slots should be positioned right along the edge (figure K) so that the cut doesn't extend through the cove. Set the fence of the biscuit-joiner to 45 degrees, and use a shim taped to the fence to serve as spacer to position the cutter precisely on the mitered edge.
- To complete the trim, measure and mark them against the sides of the case (figure L), then cut them to the proper sized at the table saw so that they will sit flush with the case.
- Apply glue to the slots, biscuits and miters to glue up the trim in the U-shaped configuration (figure M). Dry-clamp the glued molding at the base, using the base as a form so that the molding holds its shape as the glue dries.
