A traditional log structure was held together by gravity. Logs were carefully cut to length, and notched at the joining points to ensure a very tight fit, great stability, and weather-tightness. The notches were also beautiful and functional as the dovetails of a master cabinet-maker.
Here, Allan Mackie shows a complete selection of notches for corner joinery, roof beams and trusses and lateral grooves (for seating a stacked log firmly along the length of another wall log; and timber framing techniques).
Clear instructions and profuse illustrations and drawings make this a completely detailed manual for the log builder.
