Drying Hardwood Lumber
Author: Joseph Denig
Publisher:
ISBN:
Category : Lumber
Languages : en
Pages : 148
Book Description
Drying Hardwood Lumber focuses on common methods for drying lumber of different thickness, with minimal drying defects, for high quality applications. This manual also includes predrying treatments that, when part of an overall quality-oriented drying system, reduce defects and improve drying quality, especially of oak lumber. Special attention is given to drying white wood, such as hard maple and ash, without sticker shadow or other discoloration. Several special drying methods, such as solar drying, are described, and proper techniques for storing dried lumber are discussed. Suggestions are provided for ways to economize on drying costs by reducing drying time and energy demands when feasible. Each chapter is accompanied by a list of references. Some references are cited in the chapter; others are listed as additional sources of information.

Dry Kiln Schedules for Commercial Woods - Temperate and Tropical
Author: R. Sidney Boone
Publisher:
ISBN:
Category : Kilns
Languages : en
Pages : 158
Book Description
Contains suggested dry kiln schedules for over 500 commercial woods, both temperate and tropical. The schedules are written out for easy reference and use. The majority of the schedules are from the world literature with emphasis on U.S., Canadian, and British publications. Revised schedules are suggested for western U.S. and Canadian softwoods and U.S. southern pines. Included are conventional and elevated temperatures for U.S. and Canadian species, Latin American woods, Asian and Oceanian woods, African woods, and European woods. Also included are high temperature schedules for U.S. and Canadian species and tables of assembled dry kiln schedules.

Formation and Properties of Juvenile Wood in Southern Pines
Author:
Publisher:
ISBN:
Category : Juvenile wood
Languages : en
Pages : 48
Book Description
To satisfy the increasing demand for forest products, much of the future timber supply will be from improved trees grown on managed plantations. This fast-grown resource will tend to be harvested in short age rotations and will contain higher proportions of juvenile wood than that of current harvests. In anticipation of this resource, definitive information is needed on the influence of juvenile wood on lumber properties so that grading rules and the associated allowable design stresses can be modified as needed. This document reports the results of an extensive review of the literature on juvenile wood in southern pines. This report defines and discusses the extent, occurrence, and characteristics of juvenile wood. It reviews the effects that environment and silviculture have on the amount of juvenile wood produced. Finally, the impacts that juvenile wood has on mechanical properties were quantified. The results of this quantification are significant to all producers of fast-grown plantations. Research has clearly shown that juvenile wood will have a detrimental impact on allowable design stresses for visually graded lumber. It is critical that methods are developed to more carefully manage fast-grown plantation wood for its most efficient use. This review should serve as an overall collection of knowledge pertaining to juvenile wood research in southern pines and should help in the decision-making efforts to improve seedling selection techniques and silvicultural practices to maximize the potential for fast-grown plantations of southern pines.

LSY
Author: Edward M. Bilek
Publisher:
ISBN:
Category : Break-even analysis
Languages : en
Pages : 44
Book Description
A spreadsheet-based model, LSY (Log-sort Yard Cash Flow Analysis), has been constructed to aid in the pre-feasibility and financial feasibility analysis of log-sort yards. It is meant to be referred to concurrently with this documentation and is available for downloading at no cost from the Forest Products Laboratory's website at: http://www.fpl.fs.fed.us/documnts/fplgtr/fpl_gtr184/. The model is flexible, allowing up to 20 species and grades that each may be sorted into up to 19 products, giving a total of 380 different output possibilities. The mix of those species and grades can be allowed to change over time. Sort-yard operating hours and productivity and number and type of employees can be changed over time. Cash flows reflect automatic replacement of capital equipment when it is projected to wear out. Data on various pieces of capital equipment and equipment configurations can be stored so that cost comparisons can easily be made between different sorting systems.
