Abstract
The new technologies, incising, moisture tolerant phenolic adhesives and steam pressing were evaluated for the manufacture of laminated veneer lumber (LVL). Both 8- and 13-ply incised spruce LVL panels were prepared using these new technologies. The results showed that both steam pressing and self-generated steam from wet face and back veneers accelerated temperature rise in the innermost glueline of 13-ply incised spruce LVL panels. This would help facilitate faster production rates for LVL manufacture. Bond quality and edge bending values were determined for the steam-pressed 8-ply and 13-ply incised spruce LVL panels. In all cases the average % wood failure was above 90% indicating excellent adhesion between the moisture tolerant adhesive and wood. The modulus of rupture and modulus of elasticity values measured for the steam-pressed incised spruce LVL samples compared very favourably with those for a commercial Norway spruce 15-ply LVL product.

Abstract
The existing softwood kilns are vastly oversized and ill equipped to dry the volume of hardwood lumber identified for the study. A dehumidification kiln with a twenty thousand board foot (20 Mbf) capacity would be the most cost effective kiln drying technology. It would be well matched to the annual volume to be dried and does not require specialized skills to operate. Such an operation would require a price differential between green and dry lumber of approximately $120 per Mbf to be viable. Within the study area, there exists a small volume of veneer quality hardwood resource. A longitudinal veneer slicing system would be well suited to process the volume available. Such a system would process green lumber to produce high quality, sliced face veneer. White birch, however, has little figure or grain when sliced and hence, little advantage over rotary cut birch veneer. To be viable, markets for the sliced veneer would have to be developed at the current market price for rotary cut face veneer. This should not be too difficult as the volume is relatively small. The fact that suitable technology exists for the kiln drying and veneering operations is encouraging. If markets in these two areas can be developed, it is recommended that consideration be given to the concept of a wood products industrial park. Initially, the core enterprise of the park would be a lumber concentration yard with dry kilns and possibly dressing facilities. It could be expanded at a later date to include a small sawmill and the veneer operation. As markets develop, consideration could be given to other complementary industries which build on the expertise and resources of the industrial park. This concept is further detailed in the report.
