Module 1: Lathe Anatomy & Turning Theory

Overview

This module introduces the components and operation of a wood lathe, emphasizing the relationship between spindle speed, workpiece size, and safety. Students will understand how to identify wood grain direction and select appropriate speeds for different wood densities. This foundation is essential before tool technique is introduced.

Learning Objectives

  1. Identify all major components of a wood lathe (headstock, tailstock, bed, tool rest)
  2. Understand the relationship between workpiece diameter and spindle speed (RPM)
  3. Explain grain direction and its effect on tool marks and cut quality
  4. Describe wood properties relevant to turning (density, grain structure, moisture)
  5. Select wood species appropriate for turning projects
  6. Calculate or select correct spindle speed for given workpiece size
