ROTARY PEELEDu
An entire log is placed into a lathe
and rotated in uninterrupted contact
with the lathe knife, resulting in a
cut that roughly parallels the growth
rings to produce a bold and often
variegated grain pattern. The
resulting ribbon of veneer is sub-
sequently clipped to usable widths,
including sheets called whole piece
or one-piece face that will cover an
entire 4x8' sheet of plywood, as well
as narrower leaves that will later be
spliced together in order to cover
a 4x8, 4x6, 8x4, or any number
of sizes as may be specied by a
customer. Rotary cutting is the only
method of producing veneer that
will produce whole piece faces.
SLICEDu
A half or quarter log is placed on the
slicer which forces it laterally against
a knife to produce narrow veneer
sheets with somewhat more predict-
able grain patterns. These sheets will
later be joined together through one
of the various matching methods to
produce 4x8', 4x6, 8x4, or any number
of sheet sizes as may be specied by a
customer. Generally, slicing veneer
produces more of a solid lumber ap-
pearance associated with the manner
in which the half or quarter log is posi-
tioned in the slicer. Veneer leaves are
kept in order as they are cut from the
log to ensure a consistent appear-
ance, making sliced veneer generally
more prized than rotary cut veneer.
Rotary Red Oak
Whole Piece Face
Rotary Cut Veneers
Entire log is peeled producing
a continuous ribbon of veneer.
Plain Slicing
The half log is mounted with
the knife parallel to the center
or “back” of the log, then forced
across the knife to produce a at
sawn lumber look, often devel-
oping a repeating grain pattern
called a cathedral.
Quarter Slicing
The quarter log is mounted in
the slicer so that the knife cuts
across the growth rings at ap-
proximately a right angle and
parallel to the rays, resulting
in a highly three dimensional
ray ake appearance in red
and white oak.
