If any of your woodworking tools seem to be losing their zip, make sure they aren't suffering from surface drag instead of a dull blade. Rubbing a thin coat of paste wax or paraffin on the top surfaces of tools like tablesaws, planers or jointers, or onto the sole plates of portable tools like circular saws, sabersaws or even hand planes, can make a big difference in how they perform.
Structural composite panels (the APA tradename is COM-PLY) consist of veneer faces bonded to a wood-base core material, such as OSB. Composite panels are manufactured in three- or five-layer arrangements. A three-layer panel has a wood fiber core and a veneer face and back, while a five-layer panel also has a veneer crossband in the center. When manufactured in a one-step pressing operation, voids in the veneers are filled automatically by the particles or strands as the panel is pressed in the bonding process. Typical composite panel applications include sheathing, siding and industrial applications.
