For each adhesive, six wood triangular sections were used to produce three adhesive-laminated quartersawn billets.
As each piece was glued, it was placed in the clamp and oriented so that the grain of the wood would produce quartersawn or flatsawn boards when the billets were cut.
Experts recommend a reduced cutting angle when planing or moulding quartersawn
Sound boards from each species were segregated according to type of cut: flatsawn or quartersawn
. Radially cut specimens were taken from the flatsawn boards and tangentially cut specimens were taken from quartersawn
The Master grade refers to a tonewood board containing more than 95 percent quartersawn
material, no defects, no spiral grain, even grain lines, white color, good stiffness, no compression wood, and no dark growth lines.
Past research has shown that in drying of radiata pine lumber, the quartersawn
pieces need longer drying time than the flatsawn pieces.
In each case, the wood was straight-grained, free of defects, and flat- to quartersawn
. The wood was conditioned at 23[degrees]C and 50 percent relative humidity (RH) to approximately 9.5 percent equilibrium moisture content (EMC).
There is no agreement as to whether flatsawn or quartersawn wood bends better.
The wood was taper sawn and the samples were quartersawn. The samples contained no obvious signs of defects or tension wood and were taken far from the pith of the tree.
No significant differences were observed between flatsawn and quartersawn
This non-significant difference suggests that the growth-ring orientation (flatsawn versus quartersawn
) on different boards in a kiln charge should not significantly affect high-temperature SYP drying.
boards close to the pith were selected from each log.
