The goal of this project was to create a buffet / serving table to compliment the large farmhouse table I made a while back. We have been using a folding table for a buffet line at large family gatherings and that just didnt seem right when placed next to the giant 10' table. (info for the table: http://www.ana-white.com/2014/07/big-farmhouse-table)
The build is similar to the farmhouse table, but the materials are a bit smaller due to the size of the table. The legs are 2x3's and the table top itself is made of 2x6's outlining a 2' x 5' section of tile. All of the other materials (stretchers and apron) are made from 1x3s. The tile is set so it sits about 1/8" higher than the wood. This is to allow hot pans and plates to be placed directly on the tile without a trivet or other separator. The tile sets on a 3/4" piece of MDF supported by small 1x2 slats underneath.
All of the joinery is accomplished with glue and Kreg Jig / Screws.
Cost doesnt include finish materials or screws as I had them onhand already, but would probably cost $20 or less.
