Military specifications for aircraft structural plywood require that the specific gravity of the veneer shall not be less than the minimum values listed for particular species. The Forest Products Laboratory has developed a practical method by which venner for such plywood can be produced with reasonable assurance that it will meet the minimum of specific gravity requirement. By this method specific gravity of flitches and bolts is determined before veneer is cut, and wasteful cutting of low-density material is therby avoided. In most cases, this material would not prove usuable as commerical veneer, because it has been cut to special thicknesses for aircraft plywood paricularly designed for certain strength properties.
