Ever wonder what defines quarter sawn, plain (flat) sawn, or rift sawn lumber? Professional sawyer and fine-hardwood dealer Rick Hearne dissects a sample flitch-cut log to demonstrate the variety of grain orientations that can be milled from any log. It’s more than an academic exercise because each type of cut offers the woodworker specific characteristics not found in the alternate orientations. Grain patterns, figure, medullary ray, and board stability are just some of the variables that make up the mix.
In this short video, Rick briefly explains how each type of cut is defined by the relationship of growth rings to a board’s face. Quarter sawn boards have a grain orientation that is largely vertical (60-90 degrees) to each face. Rift sawn lumber is cut with the grain oriented 30-60 degrees to the boards face. And the most common cut is plain (or flat) sawn lumber with the grain running mostly parallel to the boards face. Most importantly, Rick explains why it matters. (2.5 Minute Woodworking Video)
