| Contemporary Writing Desk: Veneered Zebra-Wood Top |
From "Wood Works" episode WWK-511 |

 |

 The simple cherry base of this writing desk is offset by the striking pattern of the richly figured zebra wood.

With the writing-desk frame assembled, and the glue dried, work can begin on the zebra-wood desktop. Materials: Zebra wood and cherry stock for veneers 3/4-inch plywood stock for substrate Vacuum press Table saw Drum sander Jointer Belt sander Hand scraper Hand plane Dead-blow hammer Chalk Yellow woodworker's glue Slow-setting resin glue Glue roller Carpenter's tape Carpenter's straight-edge Clamps Safety glasses or goggles

Safety Alert: Always wear safety goggles or safety glasses when working with wood, power-tools, saws, drills, routers, etc.Once the glue in the assembled base is dry, remove the clamps and chisel the inside corner-notches of the legs square so that the top will fit snugly. The top of the writing desk is composed of a 3/4-inch substrate of apple plywood laminated with veneers of cherry on the bottom and African zebra-wood on the top. The top is 18 inches wide by 42 inches long. Since our cherry and zebra-wood stock was only 6 inches wide, we had to glue up three pieces of each to achieve the necessary width for the veneers. Preparing the Zebra and Cherry Veneers - At the band saw, re-saw the cherry and zebra-wood into veneers that are 3/32-inch thick (figure A).
- Once they are cut, run the veneers (both cherry and zebra wood) through the drum sander to achieve a uniform thickness of 1/16-inch (figure B).
- Before edge-gluing the veneers, joint one edge at the jointer (figure C).
- Also before gluing, mark the faces of the zebra-wood veneers to ensure a continuous flow of the wood grain. Take the center veneer and book-match the right side, then the left side (figure D) and then mark faces with cabinet-maker's triangles to indicate the placement of the veneers for glue-up.
- With the panels clamped together, evenly roll yellow glue onto the edges (figure E).
- Line up the triangles, add blue carpenters tape across the seams, and clamp the veneer securely. Use bricks to keep the veneer sheets flat as the glue dries (figure F).
- Follow the same procedure to glue up the cherry veneers.
- Once the glue has dried, remove any hardened squeeze-out from the faces of the veneer using a hand-scraper.

Assembling the DesktopWith both veneers complete, they can be added to the plywood substrate to create the desktop. - Cover one surface of the apple-plywood substrate using plastic resin glue. Use a glue-roller to ensure even coverage.
- Add glue to one side of the cherry veneer (figure G) and position the substrate on top of it.
- Add glue to the other side of the substrate and to the back of the zebra-wood veneer.
- Position the zebra-wood veneer on the substrate (figure H).
- Add blue tape to the edges of the "wood-and-glue sandwich" (figure I) to prevent slippage during the curing process.
- Place the taped tabletop assembly into the vacuum press, add an MDF caul, seal the bag and turn on the vacuum pump. The vacuum press will provide more than 1500 pounds-per-square-foot of atmospheric pressure. Allow 12 hours in the vacuum press (figure J) for the tabletop to cure fully.
- Once the glue has hardened, and the tabletop has been removed from the press, belt-sand one edge to remove any hardened glue (figure K). Use a long carpenter's straight-edge to ensure that the edge is straight.
- Rip the tabletop to a width of 18 inches at the table saw.
- Using the cross-cut sled, cut the top to its final length of 42 inches (figure L).
- Hand-plane the edges of the top (figure M) to achieve a perfect fit of the top into the frame. For a better fit, bevel the bottom edge of the tabletop slightly.
- To attach the tabletop to the desk, apply yellow glue into the rabbet in the frame, and to the edges of the top.
- Position the top in the frame and use a dead-blow hammer to tap it into position (figure N).
- Add good clamping pressure around the perimeter of the top (figure O).
In the segment that follows, decorative brass pins are added to reinforce the drawer joinery, an ebony handle is added to the drawer-front, and a tung-oil finish is applied to complete the desk.
