An overall method of making engineered strand wood products in relation to a number of different possible criteria is provided. Such a method may involve any combination of different screening procedures to determine the best wood sources from which individual strands may be prepared. Such screening procedures may include initial determinations of certain physical characteristics of individual logs, further or initial determinations of certain physical characteristics of portions of sawn logs, further or initial determinations of certain physical characteristics of individual strands, and any combinations thereof. Additionally, after the initial physical characteristic sorting is completed, optionally the wood may be cut into uniformly sized and shaped strands for incorporation within a target strand product. Still further, such strands, in substantially uniform size and shape, as well as substantially uniform physical characteristics, may then be incorporated into a target strand product in specific predetermined configurations. Such various possible combinations of screening procedures and / or selective stranding processes results in strand products (boards, lumber, and the like) of improved properties over previously made strand products. Thus, encompassed within this invention are processes involving each of these procedures either individually or in combination with other sequential processes for the production of desired strand products.

Wood such as spruce, maple, and hornbeam are retained in high pressure steam of pressure 0.2 to 1.6 MPa at 120 to 200° C. for 1 to 60 minutes, and subsequently, cooled and dried to obtain a modified wood having superior acoustic properties and old wood-like appearance due to a change to a deep color tone. Since the conventional modification methods by chemical treatment using chemicals such as resorcin and formaldehyde are not used, the treatment steps are simple and a modified wood used as a material for musical instruments is obtained at low cost.

A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths. The saws are adjusted in response to the computer solution and the log is positioned by a positioner according to a computer generated reference datum. This results in the log being positioned for cutting to the optimum random lengths. A command signal is sent from the computer to the log sorting system, which tracks the position of the random lengths and allows them to be sorted to the appropriate sort storage bin.
