35. t to saw Tensions can also arise in storage If the bark and top segment begin to dry the whole surface will begin to shrink In such a case when one side is trimmed the log may bend slightly It is easy to discover tension in logs that leads to measurement errors each time you pull the saw back you can read what is happening in the log As long as the guide bar continues to lie just above the newly sawn surface then the log has not bent However there is space between the guide bar and the sawn surface or if the guide bar is pressed upwards it is time to plan how the next cut should be made to reduce the effects of tensions When sawing from the top towards the bottom the wood has a tendency to bend downwards at the ends This is especially true if there is large root end growth It is therefore often best to turn the log after passing through the centre and saw the rest of the material from the other side If you still want to saw logs with high tensions a chain saw and a timber jig 4900 000 1000 to slice up the log can be a better alternative This follows the previous saw surface and therefore gives better precision if the log bends FARMERS M8 SOME TIPS FOR AVOIDING THE EFFECTS OF WOOD TENSIONS 1 Cut wood with tensions in as short lengths as possible By reducing the log length to app 2 5 m the precision will be high even if there are high tensions in the wood 2 Work around the log sawing all sides in or
