Tangential planks and boards hardly crack, but they become convex by turning their backs on the core of the trunk. Radial sawing requires sturdy logs.
Radial cut pieces hardly warp as they dry, but the core cracks easily. Radial sawing is desirable for many tree species both for technical and aesthetic reasons. The low quality core, however, should be lost.
From tangential plank to radial board
- The convex plank is split in half from the middle.
- The halves are planed from both sides.
- The halves are split in rectangular bars.
- The bars are glued together, the planed surfaces facing each other..
