How quartersawn lumber behaves

Quartersawn boards put a radial face outward, so they change width less and cup less.

When the purchase is complete, return to the original window. It will refresh.

From the opening

Quartersawn lumber is cut so the growth rings meet the wide face at a steep angle, close to square, which means that face is a radial slice through the log. Its width therefore lies more in the radial direction and less in the ring-around direction that moves the most. The opening covers rings stand steep to the face, width movement is mostly radial, and oak rays appear as fleck.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.

Inside

  • Rings stand steep to the face
  • Width movement is mostly radial
  • Oak rays appear as fleck
  • It still moves, only less
  • Where the idea stops applying
  • A distinction worth keeping
