This bowl is 8-3/8" by 1-3/4", and constructed of walnut and maple strips. The strips in the lamination start at 1/16", and increase by 1/32" increments to 1/2". Precise (!) woodworking... ;^)
After the glue had cured, the blank was cut in half, one side flipped, and then glued back together. It was then turned in a conventional manner, finished with food safe oil, and buffed with carnauba wax.
