In many developing countries wood harvesting with hand tools continues on a large scale. With the shift of emphasis towards trees grown by rural people rather than forestry enterprises, it will gain in importance in the years to come. This training manual provides basic information on efficient and safe equipment and methods for manual wood harvesting. At the same time, the information helps to ensure the fullest utilization of the available wood raw material. The manual updates previous ILO publications on the same subject, while taking into account progress and new developments observed in recent years. It is richly illustrated to make it easily accessible and will be ideal for forestry training and rural extension work. "This small book is a well-illustrated guide ..... simple to read, the diagrams are clear and are well described in the text ..... an excellent book dealing simply and in sufficient detail with a subject where current methods of operation often leave much to be desired."
The introduction of chain saws and tractors in the early 1950's marked the beginning of a change in tree harvesting techniques from the old manual methods to mechanized operations. It was followed by a rapid evolution both technically and systematically. Hence, the requirements for improved know ledge of operational efficiency also increased. Changing relations between Man, machines and environment brought about new experiences and awareness of a physiological and ergonomic nature. Improved knowledge of both machine technology and planning of work on a small or large scale has grown increa singly important for an efficient utilization of expensive machines and other equipment. The need for a textbook on tree harvesting techniques including expe riences made in recent years is enhanced. The book presented here is prima rily based on lectures given on the subject of Forest Techniques at the Faculty of Forestry at the Swedish University of Agricultural Sciences and after modifications also at the University of Nairobi (Kenya). Thus, the book is written primarily for students at the faculties and institutes of forestry. However, it is also useful for persons actively occupied in forest operations. The presentation of this book in its original Swedish version in 1972 created a considerable interest in the preparation of a condensed edition in English. Thus interest has been expressed in Finland, Norway, Holland, Canada, U.S.A., Brazil, Japan, Poland, Scotland and Yugoslavia.

This special re-print edition of William Noyes's book "Handiwork in Wood" is a guide to working in wood, from harvesting the trees, to milling them and to the completed project.Written in 1912, this classic text provides insight into everything a person would wish to know about wood working as it was done a century ago. Chapters include: Logging, Sawmilling, The Seasoning and Measuring of Wood, Hand Tools for Woodworking, Wood Fastenings, Care of the Woodshop, The Common Joints Used in Woodworking, Types of Wooden Structures, Principles of Joinery, Wood Finishing and much more.Lavishly illustrated with vintage photos and woodworking plans, this is a real treasury of historic information on wood working.Note: This edition is a perfect facsimile of the original edition and is not set in a modern typeface. As a result, some type characters and images might suffer from slight imperfections or minor shadows in the page background.
Working Wood, Not Machining It If you're more interested in working with wood rather than machining it, you will be relieved to learn that expensive powered machinery isn't required to build furniture. You can also forget the dust masks, face shields and hearing protection since many of the safety concerns related to woodworking—the use of power tools—are eliminated. In this book, you'll learn to set up a hand-tool woodworking shop, then discover the toolset, practice the skillset, and understand the mindset—effectively completing a comprehensive course in hand-tool woodworking.
Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.
