Measuring

Measuring Standing Trees: Estimating
Two measurements are needed to determine the volume of a tree, its diameter and height.
 Measuring Tree Diameter and Height
Measuring Standing Trees: Stumpage
Stumpage is the value of a standing tree with that tree being used for anything from fuel wood to veneer.

Processing

Drying Boards and Lumber 
After logs have been milled into lumber, the lumber must be properly dried to ensure quality.
Processing Wood: Maintaining Band Saw Blades - Part 1
There are three different directions to maintain when reconditioning a saw blade.
Processing Wood: Maintaining Band Saw Blades - Part 2
After finishing one direction of setting, the blade must be flipped to check the other direction.
Processing Wood: Maintaining Band Saw Blades - Part 3
After checking the alignment, the blade is ready to be sharpened.
Urban Logging: Sawing Patterns - Processing Wood
Sawing logs using different cuts creates grain patterns with a wide variety of uses.

 

Contaminants

Contaminants  
If conditions are right, surface mold will appear on many species of wood.
