Abstract: The staves for producing wooden barrels are assembled of individual segments which are fixedly connected to each other at end faces. The individual segments are shorter wood pieces that are assembled such that the stave has the required length. The wooden barrel is produced of such staves which are placed against each other seal-tightly with their narrow sides. The individual segments are machined at their end faces such that individual segments resting against each other after assembly are positioned at an angle relative to each other and form a raw stave that is curved across the length.

Abstract: A plurality of metalogs form a freestanding wall or fence, or structure comprising walls, upper floors whenever applicable and/or roof of a building. Each metalog has an axis. A stiffener extends through a set of aligned holes in the metalogs at right angles to the axes. One or more additional stiffeners may similarly extend through one or more additional sets of aligned holes in the same metalogs. The stiffeners function to resist forces acting in a direction parallel to the axes of the metalogs and therefore enhance the stability of the structure and obviate otherwise required X-bracing.
