Describing the history and state-of-the-art of the thermo-hydrous manipulation of wood, this book provides either a desk reference or a field manual of wood science. It examines the polymeric components of wood and its multilevel hierarchical structure that confer its unique general-purpose character and faculty for transformation. Exceeding all other material in its capacity to deform under controlled conditions and for a proscribed outcome, wood, under thermo-hydrous conditions, permits a multitude of industrial processes. Discussing the processes at work and the industrial applications, this book is a must for all interested in the manipulation of wood.

Wood Bending Made Simple

Wood bending is intriguing to the vast majority of woodworkers, but until now most have not had access to the information they need to add it to their repertoire. Wood Bending Made Simple, a highly visual book and DVD, changes that.

Wood bending is intriguing to the vast majority of woodworkers, but until now most have not had access to the information they need to add it to their repertoire. This highly visual book and DVD changes that. It features step-by-step instruction on some of the most common techniques. Expert Lon Schleining explains and demonstrates both steam bending (where steam relaxes wood fibers so they can be shaped when clamped to a bending form) and bent lamination (where thin strips of wood are glued together, then clamped to a bending form). Schleining shows just how easy it can be to master these techniques, even using relatively low-tech equipment.
