Tackling Large Tabletops
Make a tabletop that''s as strong as an airplane wing using torsion-box construction
The boat-shaped table featured in this article, if built of solid wood, would be unstable and too heavy, so the author made a torsion-box tabletop instead. A torsion box is constructed like an airplane wing, so it has a high strength-to-weight ratio. Author Kim Carleton Graves explains how to use a resin-impregnated cardboard honeycomb and an MDF frame between thin skins of veneer. He provides detail on cutting the core to fit the frame, building the core a layer at a time, assembling and gluing it up, using templates, building up the edges, and veneering the large surface area.
