Big Bubinga Boards About this time I was blessed with the arrival of four of the biggest and most spectacular bubinga boards you're likely to ever see this side of the African jungle. We picked the finest of these for our tabletop. In the spirit of waste-free woodworking, I made a mock-up of the top from plywood, as a study for shape and dimension. A few of us weighed in, arriving at a final dimension of 20" wide and 76" long. Turning to our prized bubinga slab, I found the tabletop dimension in an area running across the middle of the board at a gradual angle, landing on some highly figured center grain. I rough-cut it out using a circular saw and I decided to use dowels to join the end and center rails (pieces 3 and 4) to the leg-apron rail subassemblies. I carefully laid out the dowel locations and bored the holes on my drill press. Gluing and clamping these pieces to the two subassemblies wasn't that complicated, but as with any project this size, a test run is a good idea. (As is inviting a friend over to your shop to lend a hand!) The final bit of shaping on this leg assembly is to rout a slight radius on the outside edges of the legs. (See the Drawings at right for details.) When that's done, it's time to grab a sander and a dust mask and smooth the piece through the grits, right up to 220. The legs are formed in a two-step template-routing process. The second step uses the face created by the first to guide the bit.
There are three pocket-hole joints bored into each end and center rail to hold the tabletop to the legset. The pocket-hole joints to the left and right of the center hole should be drilled double-wide to allow for wood movement in the solid tabletop.
