Cutting Graphic |
Cutting Explained |
|
|
 |
ROTARY CUT
The log is mounted centrally in the lathe and turned against a razor sharp blade, like unwinding a roll of paper. Since this cut follows the log's annual growth ring, a bold variegated grain marking is produced. Rotary cut veneer is exceptionally wide. To put it simply, this is the way you peel an apple |
|
|
|
PLAIN SLICING
The log, or flitch, is mounted with the heart side flat against the flitch table of the slicer and the slicing is done parallel to a line through the center of the log. This produces a variegated figure. To put it simply this is the way meat is sliced at the deli |
|
|
QUATER SLICING
The quarter log, or flitch, is mounted on the flitch table so that the growth rings of the log strike the knife at approximately right angles, producing a series of stripes, straight in some wood, varied ion others |
|
|
RIFT CUT
Cut veneer is produced in the various species of Oak. Oak has medullary ray cells which radiate from the center of the log like curved spokes of a wheel. The rift or comb grain effect is obtained by cutting at an angle of 15 degree of the quarter |
