Natural Drying- Air/ Sun Drying
Done in dry kiln lumber is artificially dried in correct moisture content
Kiln Drying
Fibers running in the same direction as the main axis of the Tree
Straight Grain
Grains are in successive layers in opposite direction
Inter-locked Grain
Constantly changing in orientation so that a line drawn parallel their direction appears as wavy
Wavy or Curly Grain
Gain logged not sawn along its vertical axis
Diagonal Grain
Grain of tree grows twisted
Spiral Grain
fiber’s run approximately parrallel with vertical axis of log
Straight Grain
Grain direction of wood fibers has constantly changed
Wavy Grain
Fibers at directions that are varying and irregular from from log’s vertical axis
Irregular Grain
Grain structure sawn fibers lined up in opposite directions
Interlocked Grain
Grain structure sawn board is cut in grain direction but through radius
Quarter/Radial Grain
Grain structure sawn cut across the grain
End Grain
Methods of sawing : most common method, highest quality usable lumber
Plain Sawing
Methods of sawing: cuts log in quarters
Quarter Sawing
Methods of sawing: sawing through and through
Live Saw

Knots
Small knots caused by shedding of early branches
Pin Knots
Knots sliced through their length during sawing, “slash knots”
