Building a Custom Walnut and Mahogany Wine Display Case

Today in my workshop, I’m building a project that blends form and function: a custom wine display case designed to hold three bottles and two glasses. This isn’t just any box; it’s a piece I’m building from walnut, with a lid featuring genuine mahogany. My goal is to create an heirloom-quality case where every detail, from the joinery to the interior cradle, is thoughtfully executed.

Milling and Planning

The journey begins with the walnut. I’ve already jointed and planed the board square, and now I’m ripping it to a width of six and seven-eighths inches—an eighth of an inch wider than the final six-and-three-quarter-inch height of the box. This extra material accounts for the saw blade’s kerf, as I’ll be cutting the lid and the base from the same piece of wood.

But I’m not just cutting pieces to length. I want the grain to flow seamlessly around the box, like it would with miter joints, but with the strength of box joints. To achieve this, I carefully lay out the pieces—two sides, a front, and a back—so the grain pattern will wrap continuously around the corners. After squaring off an end with some bug damage, I use a stop block on the saw to ensure every piece is cut to an exact, identical length, which is crucial for the box to assemble perfectly square.

Precision Joinery: The Art of the Box Joint

For the joinery, I’ve chosen box joints for their durability. Before cutting into my precious walnut, I dial in the settings on my dado stack using scrap wood. A perfect, snug fit on the test pieces gives me the confidence to move forward. I also take a moment to create new, specialized clamping blocks from plywood. These blocks will apply pressure directly to the “fingers” of the joint during glue-up, ensuring a tight, gap-free connection without stressing the end grain.

While the joinery is setting up, I turn my attention to the panels. I’ve cut pieces of plywood for the bottom of the case and an interior tray. To elevate them, I’m gluing resawn walnut veneer to their faces using a vacuum bag, which applies even pressure for a flawless bond.

Adding Detail: Dados and a Show-Stopping Lid

With the veneer setting, I rout stopped dados into the front and back pieces to house the bottom panel. This requires careful setup with spacer blocks and a router to ensure the dados start and stop precisely, avoiding the delicate box joint fingers. A quick touch with a chisel squares up the rounded ends left by the router bit.

Then comes the star of the show: the lid. The mahogany slab from Elements Wood Imports is stunning, but the pith, or center of the tree, can cause instability. To ensure the lid stays flat for years to come, I cut the pith out and glue the two resulting boards back together. After planing it smooth, I cut it to width and use the same router setup from the base to cut a groove. This ensures the lid will slide onto the base perfectly. A graceful chamfer around the edge adds a refined touch.

Freshly milled mahogany is quite light, so I apply a custom water-based dye to enrich its color and pop the grain. By wetting the wood first, I slow the absorption, giving me more control and preventing streaks. The result, after drying overnight, is a deep, rich hue that truly does the wood justice.

The Moment of Truth: Glue-Up and Separation

It’s time for the main event: gluing the box together. With my custom clamping blocks covered in packing tape to prevent accidental glue bonds, I carefully assemble the sides, front, and back. I place two small dots of blue tape on the back piece as alignment markers for later, when I install the hinges.

After the glue cures, I sand the joints smooth. Then, with a deep breath, I raise the table saw blade to just below the surface of the wood and carefully cut the lid from the base. A few light passes with a hand plane clean up the cut, leaving a perfectly flush seam.

Finishing Touches: Hinges and Interior Fittings

For the hinges, I’m using high-quality Brusso hardware. Using their mortising template, I routed the recesses for the hinges and their unique 90-degree stop mechanism. To avoid stripping the soft brass screws, I pre-thread the holes with a provided steel screw and then carefully drive the brass ones in by hand.

Inside the case, I add a thin walnut ledge to support a small tray for notes or corkscrews. The tray itself features mitered corners and a gently curved handle, all pre-finished before a final sanding for glue.

Finally, the piece de résistance: the custom foam cradle for the glasses. I laminate two pieces of rigid insulation foam together and then use my CNC machine to carve out perfect pockets shaped for the wine glasses. After a few test runs, the final cut is flawless. I paint the foam with a green adhesive and apply flocking—a velvety powder—giving the interior a professional, cushioned finish.

The Final Assembly

After letting the flocking cure overnight, I gently blow off the excess. The foam insert for the bottles is a friction fit, so it slides snugly into place without glue. The glass cradle, however, gets permanently installed. I carefully mask off the surrounding area, apply glue to the case, and slide the cradle into its final home.

And with that, the project is complete. This walnut and mahogany case is more than a display; it’s a functional piece of art, built to protect and showcase a prized wine collection for generations to come.
