I've been working on this serving tray on and off for several weeks, and just got it finished yesterday.
The bottom is about 10" by 16", composed of 110 equilateral 60° parallelograms, each about 1¼ inches oer side. The three woods used are walnut, cherry, and poplar.
The sides and ends of the tray are half inch thick cherry, and are beveled and mitered at 15°.
Finish is two coats of Sealcoat®, followed by three coats of Arm-R-Seal®.
The glue-up was a real challenge, and I could only do one row at a time, so it took quite a while to do, but I really like the result.
