What issue is associated with logs that are not well rounded or have an off-center pith?

• A. They result in shorter wood fibers but stronger veneer.
• B. They result in undesirable grain patterns and are likely to buckle.
• C. They improve veneer color uniformity.
• D. They reduce drying time.

Answer: (B)

Logs that aren’t well rounded or have an off-center pith create uneven geometry and growth patterns that show up in veneer as irregular grain and internal stresses. When the veneer is peeled, the growth rings are not centered under the peeling plane, so the grain looks distorted and the sheet carries mismatched stresses. As the veneer dries, this uneven structure shrinks differently across the sheet, making it prone to buckling. So the issue tied to these log flaws is undesirable grain patterns and a higher likelihood of buckling during processing. The other outcomes—shorter fibers with stronger veneer, improved color uniformity, or reduced drying time—don’t explain both the grain irregularities and the tendency to buckle produced by an off-center pith.
