Not every woodworker is going to be sawing logs to get their wood. However, whether or not you saw your own wood, there is still a lot of great information in this video.
Plain Sawn – Boards are cut tangential to the growth rings, so that the rings make angles of less than 45° with the faces of the boards.
Rift Sawn – Boards are about 30-60 degrees to the face of the board, but 45 degrees is the most optimum.
Quarter Sawn – Boards are about 60-90 degrees to the face of the board. These boards are more resistant against warping with changes in moisture.
