Shop injuries often can happen when something is difficult to remove and excess pressure is applied. When using heavy force, especially with tools like a screwdriver or a needle-nose pliers, think ahead to what will happen if the tool slips off. If it could hit a part of your body, search for an alternative removal method.
The original engineered wood, plywood consists of veneers arranged in perpendicular layers. The layers consist of veneer plies laminated with the grain running in the same direction. There are always an odd number of layers, with the grain of the face layers typically oriented parallel to the long dimension of the panel. It is the cross-laminated lay-up of veneer that gives plywood its excellent strength, stiffness and dimensional stability. In addition to a variety of sheathing, siding, sanded and concrete form grades, many manufacturers can produce custom lay-ups for specialized applications.
