A process is described for making a laminated wood product having improved strength and dimensional stability (i.e., less warping caused by temperature and/or moisture change in drying, transportation and in use). Adjacent surfaces of lumber or veneer laminae cut from a single piece of wood are arranged in units of three laminae where the center lamina is twice the thickness of each outside lamina and in such a way that the outer laminae are rotated 180 degrees about their longitudinal axes to provide mirror images of the surfaces of the center lamina. These trios are arranged in a symmetrical manner about the central plane of the laminate and then bonded together. The minimum number of laminae is three, but with increments of three additional laminae the mirror-laminate can be built up to any desirable thickness. The mirror-laminate may be used in rough form or surfaced to specific finished dimensions. It is an improved value-added product which is stronger than a solid piece of wood of similar quality and size.
