Learning Objectives

Indicator: 1.5.2.LI.2 - Outline the processing phases of timber in the woodwork industry

By the end of the lesson, learners can:

List, in the correct order, the five main processing phases of timber from felling of the tree to the final seasoned product.
Describe what happens at each processing phase (felling, conversion, seasoning, machining, and preservation) using correct technical terms.
Explain the difference between the two main methods of timber conversion: plain (through and through) sawing and quarter sawing.
Compare the advantages and disadvantages of at least two conversion methods, giving reasons for choosing one method over another in a given situation.
Outline at least two main methods of timber seasoning (air seasoning and kiln seasoning) and state one advantage of each method.
