Different techniques and sophisticated equipment are required to slice hardwood logs into thin layers of decorative hardwood veneer.
The log rotates toward the blade and is peeled off one continuous or semi continuous roll. This produces long wide sheets with a long wavy grain pattern. Many species of wood in rotary cut veneer are used for the inner plies of plywood (core) but other high grade hardwood species are used for the decorative faces of the plywood.
Slicing is done parallel to a line through the center of a log cut in half. It is sliced by raising and lowering the log against the blade yielding a veneer that looks like a sawn piece of wood.
A quarter of a log is mounted on the flitch blade so that the growth rings hit the blade at a right angle. The quarter slicing method produces a straight grain effect.
This method is achieved by mounting a log on an off centered lathe and produces a combination of patterns between rotary and plain sliced.
The cut is made at a slight angle in relation to the position of the quartered log of wood. This brings a ‘’comb’’ or rift effect to the grain of the wood.
A stationary blade slices a travelling board of flat sawn lumber length wise.
