Quartersawn white and red oak are my favorite woods. The vertical lines on the end grain in the photo above are the growth rings, and the thin, almost horizontal lines are the medullary rays that radiate from the center of the tree out to the edge. When a ray crosses the surface of a board, the flaked figure appears. Quartersawn logs are more stable and are less likely to shrink, expand, and warp.
Quarter-sawing maximizes the beauty of Medullary Rays and Growth Rings of White and Red Oak. Above is an animation of the quarter-sawing process and the beautiful wood grain characteristics of the quartered and rift boards that result.
