Abstract:
1. A method of joining a plurality of elongate log members using mortise and tenon joinery in which the log members each comprise a natural log member which is elongate in a longitudinal direction of a respective longitudinal axis and which has an outer surface comprising a natural irregular profile of varying radial dimension relative to the longitudinal axis along a length of the log member, the method comprising: selecting a first log member from said natural log members to comprise a mortise bearing member; identifying the longitudinal axis of the first log member extending centrally through the first log member in the respective longitudinal direction along the length of the first log member; selecting a second log member from said natural log members to comprise a tenon bearing member; identifying the longitudinal axis of the second log member extending centrally through the second log member in the respective longitudinal direction along the length of the second log member; forming a tenon at one end of the second log member comprising a first mating surface of reduced diameter relative to the natural irregular profile which is coaxial with the longitudinal axis of the second log member; measuring a selected distance in an axial direction between the first mating surface of the tenon of the second log member and the longitudinal axis of the first log member; forming a mortise socket in the first log member comprising a second mating surface in which the mortise socket is arranged to matingly receive the tenon therein such that the first and second mating surfaces are abutted with one another; wherein the mortise socket is formed to have a depth relative to the outer surface comprising the natural irregular profile of the first log member such that the second mating surface is located at said selected distance from the longitudinal axis of the first log member when the first and second mating surface are abutted with one another.
