Principles of Log Building

First pick the ridge beam, roof joists and other long special logs among the logs available.
Number the logs and record the measurements in a log list. Measure dimensions such as butt diameter, top diameter and length.

  • The bottom tier is the first layer of logs on top of the foundation.
  • Log preparation includes debarking and trimming.
  • When roundness is removed from the log, the corner joint becomes tight and neat.
  • Traditionally, the log has been set so that it curves upwards. Nowadays, a round log is placed on its side, in other words the curved back comes away from the wall.
  • The cross-grained cells of wood are less resistant to weather changes, and these should face the inside of the building.
  • When lifting a log, it is recommended to tie a rope at the end of the log so that the rope can be used for guiding the log from the ground.
  • Logs can be moved safely by using appropriate tools.
  • Set the log in place on the basis of the centre line of the log or the surface of the interior wall. You can use a spirit level and tape measure here.
  • The log is secured in place using special holding hooks.
  • The log can be hewed in place without pre-cutting a longitudinal groove, by using a pen marking.
  • The corner joints must be drawn accurately.
  • Once the drawings have been made accurately, the cutting of the joints can begin. Otherwise, this can be a rough sawing, after which the setting and drawing of logs are repeated.
  • The hewing begins with the cutting of the longitudinal joint.
  • Any protrusions are removed from the joint to the overhead log by means of a barking iron.
  • A well-drawn and carefully-hewed log will fit well into place.
  • When the frame is in place, the holes are drilled, and the log seams are stuffed and provided with tenons.
