Greek Key Desk
This is an original design by Armand Sussman, an amateur furniture maker living in Pennsylvania. The design creates an illusion of wood twisting and turning. By using contrasting woods, an endless stripe is created, adding movement to this piece. The glass top serves as a work surface, but it doesn’t obscure the base. The numerous lap joints (called “step-miters” by Mr. Sussman) have been worked into a novel Greek key design on the ends of the desk, which is built using cherry and walnut.
The desk is constructed by laminating strips of wood together. By making some of the layers shorter than others, you make the joints for attaching that lamination to another. As a result, all of the materials for this project must be machined precisely. Any variances will show up as gaps in the joints after final assembly.
Tricks to Dead-on Components
On to Assembly
Start by gluing the E pieces and two sets of the D pieces together to form a shallow “U.” (When gluing these step-mitered joints, I found it best to use polyurethane glue. It provides a strong bond for this type of joint.) I dry-fit all the parts to be sure I would be able to get all the pieces to come together tightly. After applying the glue, clamp the length of the E pieces first. By using 3/4″ spacers at the ends of the D parts, applying even clamping pressure is easy on the lengths of the D parts. Make two of these assemblies.
The next assembly consists of the C, B and A parts. The glue-up of this assembly is done the same way as the E and D assembly. Make four of these assemblies.
Next glue one of the E and D assemblies and two of the ABC assemblies together to form the Greek key part of the end assembly. I had to clean the glue squeeze-out at the joints and pare the wood down in a couple places with a chisel to get a tight fit. If your pieces don’t come together tightly, your joints will not be strong.
For the next assembly, put two glue-up jigs at a right angle. This makes the glue-up of the two legs (F) to the Greek key assembly easy to keep square.
Glue the F4 and F5 pieces to the tops of each leg. Use a stop block to keep the pieces even with the end of the F3 piece of each leg.
The G pieces attach the two end assemblies together. It is easier to control gluing and alignment of the G1 pieces if they are glued into place one at a time, starting at the bottom and working up.
Sanding and Finishing
I used a random orbital sander, going up to 150 grit sandpaper. Break all the sharp edges with a sanding block using 150 grit sandpaper. For a top coat, I applied three coats of a clear finish.
For the top I used a 1/2″-thick piece of 30″ x 50″ tempered glass polished on all edges. (To keep the glass in place, use six clear door bumpers applied to the top stretchers.) It wasn’t until I completed this desk and had the glass top in place that I appreciated how striking it looked. PW
