A Monumental Coffee Table

Well, its a new year and its time to get back to the too-ignored blog. So here goes.

Currently in the shop is a very substantial coffee table, made from 3" thick slabs of Claro walnut. 

Unfortunately, unlike the rendering, the actual top slab has some significant checking going on, so first order of business was to get that under control. This is an air-dried slab, so its moisture content is only down to about 12%. That means itll experience more seasonal movement than a fully dried piece would, but the big crack can be stabilized using butterfly keys (a technique popularized by the great George Nakashima). The first step was laying out a pleasing arrangement, which I did with paper cut-outs of various sizes.

After the layout was set, the butterfly keys were milled from 4/4 wenge stock using a simple band saw jig.

Once the keys were milled and inlaid into both the top and bottom surfaces, the edges were shaped. The curves were rough cut with a jig saw, then faired using a hand plane and sanders. You can see the installed butterflies in the photo, as well.

Heres what it looks like with all the edges shaped and faired.

Check back periodically over the next few weeks to see how the base unfolds....
