METHOD OF LOG SAWING

Page 3: Method and manner

Plain Sawn•Commonly referred to as “flat

sawn”. •Most common and widely used

method of sawing. •Produced by making the first cut

on a tangent to the circumference of the log.

•Produces the widest possible boards with the least amount of log waste.

•It is more economical in comparison to the other sawing techniques utilized within the industry.

Page 4: Method and manner

Quarter Sawn•Produced by first quartering the log

followed by sawing it perpendicular to the annual growth rings.

•Creates more log waste and therefore the end result of thinner boards in relation to the plain sawn technique.

•More stable than plain sawn, being less prone to distortion that comes with expansion and contraction from absorbing and releasing atmospheric moisture.

Rift Sawn•Rift sawing is very similar to that

of quarter sawing producing similar limitations and advantages.

•The most stable boards, and also the most wasteful to produce.

•There are large triangles of waste left from between each board.

•Costly to produce and therefore, the most expensive type of planks available from a log.
