The leaves are fastened to the table-top with rule joints, in which the top's rounded-over edge mates with a cove cut along the edge of the leaf (Inset). Start by rounding over the edges of the top, using a piloted round-over bit in a router. To shape the leaves, install a piloted cove bit whose diameter and profile match the round-over bit, then mount the router in a table. (The two bits are often sold as a set.) To support the leaves during the cut, clamp a featherboard to the fence above the cutter. Align the fence with the bit's pilot bearing so the cutting width will equal one-half the cutter diameter. Set the depth of cut to reach the final depth in several passes. Feed one leaf into the bit, bracing its edge against the fence (right). After each pass, test-fit the pieces; continue cutting until the top and leaf mesh with a slight gap between the two. Repeat the process on the other leaf.
