Live Edge Spalted Sycamore Coffee Table
I was recently asked to build a live edge coffee table for a special client. So, it was off to the sawmill to see what the slab inventory looked like. The customer was very fond of a specific piece of spalted sycamore. The slab had a large through and through crack as well as knot splits and surface checking. All of those “defects” would be dealt with during the preparation of the slab. Maple was chosen for the base. Initially, Norway maple was selected, however, it proved to be unsuitable during the subsequent milling.
The raw slab was slightly thicker than 1 3/4″ with a bit of twist. I used my router sled to remove the twist and bring the slab to a final thickness of 1.5″. The through and through crack would need to be filled. I chose black tinted epoxy for the job. It took four pours to completely fill the crack consuming almost 6 ounces of five minute epoxy. The knot cracks and surface checks were also epoxy filled. There were some sedge splits that were also filled. Overall, I was happy with the outcome. The black epoxy complimented the spalted surface and blended in quite well.
With the voids filled, it was now time to start the structural repairs for the top. I made a batch of butterfly splines from spalted sycamore in a variety of sizes. For the large central crack, I used a total of eight splines (four on each side). The knot cracks received an additional four splines. The sequence of work for the repair was layout the location for the butterfly, route out the rough opening, pare the opening to the final size, glue in the butterfly and trim flush.
With all of the repair work complete, the top was shaped and sanded to 800 grit.
My attention now turned to the base of the table. Initially, I planned to use Norway maple for the base, but it proved to be too brittle and prone to cracking. I switched over to hard maple instead. I was lucky because my hardwood supplier had a good inventory of hard maple shorts suitable for building the base. The base was made from 8/4 maple. The table base is a scaled down version of George Nakashima’s Frenchman Cove Table dining table.The joinery employed was bridle joints similar to the joinery employed by Nakashima. The feet and stretchers have a double taper.
The end assemblies were glue and pegged. The base breaks down into 3 parts for flat shipping.
As previously mentioned, the top was sanded to 800 grit. That involved machine sanding to 400 grit and then hand sanding to 800. At 800 grit, the table surface took on a nice shine. The finish used on the top and base are Odie’s oil and Odie’s wood butter. If you have not tried these products, I can say that they are becoming my go to finish for this type of work. Odie’s oil is like a friction finish. The heat associated with working it into the surface helps penetrate the pores and cure the finish. Application is simple. Apply the oil, work it into the surface and then wipe off the excess within 24 hours. After a three day cure, the wood butter is applied in a similar manner.
The top is joinedto the base using #10 screws in slotted holes. This allows for seasonal changes due to humidity swings.
Overall, this table is 52” L x 18.5” H x 16-22” W. The top is 1.5” thick.
With the work completed, the table was packed for shipment to the client in California.
