Quartersawn, Riftsawn and Flatsawn
Have you heard the terms quartersawn, riftsawn and flatsawn and wondered what on earth they mean? Our friends at Zena Forest Projects offer a wonderful and detailed explanation of the differences on their blog. A portion:
The above illustration shows how boards are cut out of a quarter of a log. 4 of the boards are labeled “quartersawn”. The growth rings on these boards are oriented at an angle of between 60-90 degrees to the wide face. This is the most accepted definition within the industry. The 3 smallest boards are labeled riftsawn, and we will get to those in a minute. For those who want to explore this further, here is a cool animated video about the quartersawing process.
