Abstract (en)
[origin: WO03023158A1] A process to enable the manufacture of tapered house building logs of various diameters, which would be used in hand-crafted round log construction, in both residential and commercial applications. A milling process would remove wood to create the lateral notches, also known as grooves or copes, on the underside of each wall log, while maintaining the natural taper of each whole log used. The convex curvature of the top of each log is milled to match the concave curvature on the bottom of the log sitting directly above it, using a common curvature for specified diameters; in the process of planing the top and the underside of each log, the same degree of taper is achieved. Whole, round trees are utilized and the natural taper of each log is always maintained.
