Here is a zigzag dining table in jarrah that I designed to match my zigzag chairs. Its frame consists of two Z-assemblies (made from 2" x 3" stock, joined by three stretcher rails (2" x 2 1/2"). 8 mm dominoes were used for all the joinery, which is similar to that of the zigzag chairs. The top is 7/8" x 38" x 68". The table seats six easily. I used 7/8" x 7/8" x 1 3/4" glue blocks screwed beneath each end of the top stretchers to reinforce the joints against racking.
