A Shapely Top for that Leggy Console

0

With the shapely base for the console table completed, the next step in this project was to make the equally shapely top to go with it. Because of the shape and detailing of the top, I decided to make it using shop-cut veneers. This way I could achieve the most consistent color and grain match. It was more work that way, but made for a more stable platform in the end. The first step was to cut and fair the marine plywood substrate. Next, the leaves of veneer had to be jointed and glued together. At just over 7 long and only 3/32" thick, the veneer leaves were much too flexible to joint on a machine. So, I turned to an age old hand tool technique. Adjacent veneer pairs were sandwiched between two pieces of plywood to make a shooting board, of sorts, so they could be planed for a perfectly matched joint.

The jointed leaves were then taped together and their edges glued before being pressed to the substrate in a vacuum bag.



After the bottom face was pressed, a chamfer was cut in the front edge. The chamfer was then veneered and faired. Before the top face was pressed, T-nuts for mounting the drawer pivots and stiffener were mortised into the top surface of the substrate. The mortises were then filled and leveled before the top face was pressed.

Once the top face was pressed, the front edge could then be faired to final shape and the drawer pivot post and leg attachment mortises could then be cut.


Finally, the top face was mortised and stringing inlaid. To make the string inlay fit easily into the tight curve at the ends of the top, it was pre-bent before insertion using a simple clothes iron for steaming, and the edge of the original top template as a form.

Once the top was completed, it was time to tackle the drawers. Stay tuned....

New Project A Leggy Console Table

0

My newest commission is an entry console table that features swoopy, sculptured legs and two curvy drawers for small items like keys and such.


Complex legs like these start with a paper pattern printed full-scale from the computer model. The patterns are placed on the plywood template material such that the mating edges of the parts line up with the straight-and-square milled plywood edges.



Once theyre rough milled on the bandsaw, theyre smoothed and faired by hand with rasps and sandpaper.



The parts are then laid out on the rough lumber to take best advantage of grain.



Once theyre rough milled, again on the bandsaw, the mating edges are trimmed straight using a straight-edge saw guide.



After the mating faces are established, dadoes are cut across them to form bridle joints.



The next step is to trim them to exactly match the templates using the router table. In a design like this, with highly curved parts that meet at variable angles its important to leave flat ears to act as clamping aids.



The next step is to mill and attach the contrasting feet. To create a pleasing look, its important to maintain a continuous grain flow from leg to foot. With legs that are square in cross-section, structural integrity can be maintained by creating the foot by just veneering the bottom of the leg. But with curved legs that are rounded in cross-section its much easier to simply attach a solid foot to the leg that can be shaped and smoothed with impunity. Because the joint between feet and legs in this situation is, by necessity, an end-grain to end-grain joint, it has very little structural integrity. Therefore I always support this type of joint with a mechanical fastener, aka, a screw. Once the pre-drilled foot is glued in place, a pilot hole is drilled into the leg and the screw inserted.



Once the foot is attached, the leg can be tapered and rounded. Because the tapered legs change in thickness along their length, the radius of the edges has to change, as well. To make this easier, I use several round-over router bits of increasing radius as I move up the leg. This makes creating a consistently changing edge profile a snap.



Here are the four back leg pieces dry fit together. You can see the floating bridle tenon that connects all four pieces, as well as the positions of the clamping ears at critical points.



Then its just a matter of gluing it all up.




After the back leg sub-assembly has dried, the clamping ears are removed and the final fairing completed.



Et voilá, the assembled base.



Stay tuned for more as the piece progresses.
