Rotary veneer is produced by centering the log in a lathe and turning it against a broad cutting knife which is set into the log at a slight angle. Rotary cut veneer can be sufficiently wide to provide full sheet (one piece) faces. Follows annual growth rings creating a bold variegated grain.
Rift-cut veneer is produced from the various species of oak. Oak has medullary ray cells which radiate from the center of the log like the curved spokes of a wheel. This straight grain cut is at a slight angle to the medullary rays in oak to minimize ray fleck (flake). Used on oak species, this method avoids the prominent “flake figure” of medullary rays that quarter slicing causes.
