Quarter sawn and rift sawn timber 

Quarter sawn and rift sawn timber. Measurement of angles

Most common plain sawn timber may contain both quarter sawn and rift sawn sections in the resulting wood.
With quarter sawn, the growth rings intersect the board’s face at angles of 60-90 degrees. With rift sawn the growth rings fall between 30-60 degrees. To identify quarter sawn and rift sawn timber the Pitago optimizers measure angles at three cross-sectional points of each board. Measurement points and angles, in degrees, between growth rings and the saw plane are indicated on the cutting patterns. (85°-81°-51° the below). The number and locations of measurement points is unlimited.
