Recovery of Structural Grade Veneer from Four Species of Southern Hardwoods

Yellow-poplar, sweetgum, blackgum, and white oak veneer blocks were peeled in a southern pine mill to determine yield of veneer by grade for use in the manufacture of structural plywood. The 515 blocks cut from trees 12 to 22 inches DBH were peeled into 1/6-inch veneer and the veneer graded using southern pine veneer grading rules. Veneer yields by grade for trees and blocks are presented and compared to veneer yields for similar size southern pine. Equations for predicting tree and block veneer yields for hardwoods processed in a pine mill are presented.
