Turning logs into useable timber

View the process in animation
 

1) The first several cuts are made across the top of the log. The first cut produces a slab piece and additional cuts produce boards with bark on both edges.

 

2) In this illustration, the log has been rotated 180° to sit on the first flat that was made. There are now two parallel flats. Logs like this may be used for 'landscaping' timber etc.

 

3) By rotating the log another 90° and placing one of the flats against the perpendicular side supports, another flat can then be cut. Once the top slab is removed, each cut will produce a finished, edged board.

 

4) If the log is turned a further 180°, a final flat can be cut to square the log to a finished size. From this point, beams, boards etc are sawn to size to the customer's requirements.

 

5) There are various ways of sawing the log to produce the required timber.

 

6) Some customers require 'waney' edge planks for barn cladding etc, others require 'square edge' boards, beams etc.
