Abstract
Pacific Forest Products Limited began commercially thinning Douglas-fir dominated second-growth forest on southeastern Vancouver Island with mechanized shortwood systems in 1992. In the summer of 1994, FERIC monitored a thinning operation near Cowichan Lake to determine productivities, costs and impacts to sites and residual stands. The thinning treatment was carried out with a Timberjack 1270 harvester and a Timberjack 910 forwarder.

Abstract
Le trieur Pulpwood Sorter de Simco/Ramic a fait l'objet d'essais dans le but de déterminer s'il était capable d'extraire des copeaux sans écorce destinés à la pâte, à partir de copeaux produits en forêt et contenant des quantités connues d'écorce et d'autres débris. Les essais portaient sur quatre types de copeaux: des copeaux de feuillus provenant d'arbres entiers, des copeaux de résineaux provenant de troncs entiers, des copeaux de résineux provenant d'arbres entiers et des copeaux de feuillus produits par une ébrancheuse-écorceuse-déchiqueteuse à fléaux. Les résultats des essais donnent les proportions de copeaux acceptés et de résidus combustibles en pourcentage de l'approvisionnement total à l'entrée, et le rapport estime également le coût de triage par tonne métrique verte.

Abstract
With the appropriate mainline attachment, chain chokers are a viable alternative to conventional wire rope chokers, particularly for small-scale operations. This report provides users of tractor-mounted winches and cable skidders with technical information on chain chokers. The report covers type of steels, chain specifications and grades, and how to inspect chains for wear elongation. The various components (e.g. sliding hooks, rings) used to assemble chain chokers are also discussed.

Abstract
This report provides detailed estimates of current delivered roundwood costs for lumber and pulp, as well as the costs of forest biomass harvested in a system integrated with the roundwood harvest. Three different harvesting systems were studied: full-tree to roadside, integrated cut-to-length and full-tree chipping, and cut-to-length. Two typical site types were used: a boreal softwood site and an Acadian mixedwood site. Results are presented in $/m3 and in $/gmt (green metric tonne) for both roundwood and forest biomass. The effects of haul distance, biomass moisture content and the utilization rate of the biomass production machines on total cost are analyzed. Other factors that affect the viability of forest biomass as an economic source of energy are discussed.

Abstract
L'alignement précis des équipements de coupe est un moyen recommandé pour assurer la maximisation du rendement matière et de la qualité des produits manufacturés. Les tendances de l'industrie s'orientent de plus en plus vers l'utilisation de scies minces et vers une réduction maximale des dimensions-cibles. Il est essentiel pour la qualité des produits désirés que les préposés de l'entretien et de l'alignement des machines fassent un ajustement de haute précision. Le succès d'un alignement précis dépend en grande partie de la précision des outils utilisés pour accomplir ce travail. Un niveau de précision est calibré de façon telle à permettre de mesurer les déviations du nivelage par unité de millième de pouce. Ce livre propose des formules pratiques que l'expérience en milieu de travail peut mettre à profit. Les méthodes d'alignement s'appliquent à l'ensemble de la machinerie des centres de transformation: équarrisseuse-déchiqueteuse ("Chipper Canter"), scie de tête à ruban avec le chariot, scie de tête à rubans jumelés ("Twin Band"), refendeuse verticale, refendeuse à ruban horizontal, scie de tête circulaire avec le chariot et déligneuse à scies multiples ("Bull Edger").

Abstract
Composite panels were manufactured from waste wood and recycled, mixed plastics. The effects of key processing parameters including wood fibre content on the mechanical and physical properties of panels produced were evaluated. Chemical treatments of the recycled wood fibre were conducted to improve the dispersion and adhesion of fibres within the matrix. The morphology of the plastic/wood interface was examined critically using a scanning electron microscope (SEM). Experimental work on the hot processing of panels showed that a commercial high speed mixer, (K-mixer) failed to produce a uniform dispersion of the composite materials. The wet process studied presented a good option fro making composites from recycled wood and plastics. A significant improvement in bending strength and stiffness was observed for panels containing up to 60% wood fibre. However, because of the large amount of water required for the wet process, this technique was considered a less desirable approach. Dry processing appears to be the most environmentally sound method and produced panels with mechanical properties similar to those produced by the wet process. The SEM study on fracture interfaces elucidated the relationships between wood fibre/plastic matrix and mechanical properties of panels. Chemical treatments of recycled wood fibres were found to relieve the compatibility problem between wood and plastic, improving the adhesion between these components. Experimental work has also revealed that a commercial microwave generator can be employed to preheat mats prior to hot pressing.
