Excerpt from A Treatise on the Construction and Operation of Wood-Working Machines The want of that scientific consideration to which wood machi nery is so fully entitled, must in a great measure account for the imperfect manner in which much of it is made. In many, if not in the majority of the shops in America, there is no system of drawings, no standard for bearings, bolts, or shafting the metal in the framing is disposed in the most unaccountable manner, in fact there is nothing approaching the standard of our machine tools, except the paint, which is laid on in variegated profusion. But it is outside the province of this work to criticize, inasmuch as it is not assumed to be a regular text-book. Yet it will not be amiss to stir the matter up, and thus provoke the attention which the importance of this great interest demands.

The Shakers produced many incredible furniture objects that we continue to venerate today. For the woodworker the fascination is often rooted in the essential simplicity of the work. Interest in Shaker design is as strong today as it was when the first edition of this book was published in 1977, possibly stronger. This ongoing interest is the direct result of the inherent beauty of Shaker design—beauty that stems not only from form, but from superb workmanship, a commitment to utility and a total understanding of material.

Wood as an engineering material can be technically defined “as a hygroscopic, orthotropic, biological, and permeable material having extreme chemical diversity and physical complexity with structures, that vary extensively in their shape, size, properties and function”. Therefore, using wood to its best advantage and most efficiency in engineering applications, specific characteristics or chemical, physical and mechanical properties must be considered. The products are divided into two classes, solid wood and composite wood products. Solid wood includes shipbuilding, bridges, flooring, mine timbers, etc. Composite wood products include insulation board, plywood, oriented strand board, hardboard and particle board. In recent years, the machining of wood products has acquired great importance due the short supply of wood and increasing environmental awareness among users and manufacturers. The optimization of the machining process centers around the mechanism of chip formation, tool wear, workpiece surface quality, crack initiation and propagation of different types of wood. Other factors are also humidity, temperature, static preloads, and vibrations that can affect the wood during the machining process. The book provides some fundamentals and recent research advances on machining wood and wood products.

. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.
