Base Assembly

1. Cut the torsion box parts (A1-A3). Lay out tire rib positions on the top and bottom panels and assemble with brads and glue (Photo 1). I use polyurethane glue here because it does not require much clamp pressure.

2. Cut the base panel (A4) and veneer with sapele (VI) on both sides (see "Veneer The Panels", page 53). Use scrap veneer for the underside where it won't be seen.

3. Locate the base panel so it overhangs the torsion box by 1/8-in. on all four sides and mark the outline on the shelf. Clip the heads from four small brads and set them point-up in predrilled holes inside the marked corners on the base panel. Align and press the torsion box onto the brads before gluing. This will locate the shelf during glue-up, and resist slippage as clamps or weight is applied.

4. Glue the bottom panel to the torsion box (Photo 2).

5. Cut the baseboards (A5 and A6) and run a stopped groove on the top edge of the back baseboard to accept the back panel flange (Fig. A, Detail 1, page 52). Ease the outside edge of the groove slightly to make panel insertion easier.

6. Miter the baseboard to fit around the base panel.

7. Cut biscuit slots to join the baseboard to the base panel (Photo 3) and to reinforce the baseboard miters. Position the slots so the baseboards are slightly higher than the top of the panel.

8. Glue and clamp the baseboard to the panel (Photo 4).

9. Clean up glue squeeze-out, and plane the base-

The back panel has a light colored maple veneer on one side and dark Macassar ebony on the other. The panel is secured at the top by rare earth magnets so the panel can be reversed in seconds.

Exploded View

The cabinet base is built around a flat and structurally rigid Baltic birch torsion box with leveling feet. The glass shelves are supported on shopmade aluminum shelf pins. The long pins suspend the shelves, which are the same width as the veneered portion of the back panel, so they appear to float in the cabinet.

Order 3/8-in. thick plate glass with a flat polish on all four edges. A slight bow on the front edge is a subtle but pleasing detail that breaks u:p the linear lines of the cabinet.
