Our friend David Allard and the talented furniture makers at Lyndon Furniture are always coming up with some new, exciting wood furniture design project. Check out this huge custom walnut slab table they recently finished. It's 13.5' long and the two planks in the top are made of 1 ¾" thick solid black walnut.
The legs are made of welded steel tubes that thread through the walnut slab top like through-tenons. On the top, Dave left a gap between the 2 walnut slabs to allow for wood movement. Believe it or not, even kiln-dried wood (like these walnut slabs) expands and contracts quite a bit with changes in humidity and temperature.
Such a simple elegant design, isn't it? But as any amateur woodworker could attest, it's not one to try at home unless you've got the hand of a trained professional. And a crane :)
