Dimension Yields from Yellow-poplar Lumber


Book Description

The available supply of yellow poplar (Liriodendron tulipifera L.), its potential for new uses, and its continuing importance to the furniture industry have created a need to accumulate additional information about this species. As an aid to better utilization of this species, charts for determining cutting stock yields from yellow poplar lumber are presented for each of the five top grades. Adjustment charts present the changes for specified width cuttings, also by grade. Yield and cost comparisons are made for various grades and grade mixes, with a case study used for illustration. The data should aid manufacturers by making possible comparison of study yields with actual mill yields, comparison of various grade yields with one another, and the evaluation of grade mixes for most efficient production of cutting bill.




Cutting Yields from Standard Hardwood Lumber Grades when Gang Ripping


Book Description

This publication contains charts in nomogram form that can be used to determine furniture cutting yields from hardwood lumber graded by standard National Hardwood Lumber Association (NHLA) grades when that lumber is initially processed by gang ripping rather than by the more conventional crosscutting. Prior research by Englerth and Schumann developed nomograms for the prediction of clear cutting yields when standard-graded hardwood lumber is conventionally processed by crosscutting first.
