Activity 001: Tool Identification and Selection Exercise

Activity ID: U7M2-ACT-001 Duration: 30 minutes Objective: Identify all major wood turning tools by sight and select appropriate tools for given turning scenarios.

Overview

Students examine a complete set of turning tools, identify each by name and type, then work through scenario-based selection exercises that reinforce when each tool is appropriate and, critically, when certain tools must never be used.

Materials & Equipment Needed

• Complete turning tool set: spindle roughing gouge, spindle gouge (3/8" and 1/2"), bowl gouge (3/8" and 1/2"), skew chisel, parting tool, round-nose scraper, square-end scraper
• Tool identification cards
• Scenario worksheet
• Magnifying loupe (10x) for examining edge condition

Instructions & Procedure

Phase 1: Identification (10 minutes)

1. Lay out all tools on the bench.
2. For each tool, identify: name, flute profile (if gouge), cross-section shape, tang vs. socket construction, approximate bevel angle.
3. Use the magnifying loupe to examine the cutting edge of each tool. Note which tools are sharp vs. dull.
4. Record observations on the identification worksheet.

Phase 2: Scenario Selection (10 minutes)

Work through each scenario and select the correct tool(s): 1. Rough a 3"x3" square maple blank to round for a table leg — which tool? 2. Cut a decorative cove on a spindle — which tool? 3. Produce a glass-smooth planing cut on a cylinder — which tool? 4. Hollow the interior of a 10" bowl blank — which tool? 5. Part off a finished pen blank from waste stock — which tool? 6. Smooth the interior bottom of a finished bowl — which tool? 7. Critical safety scenario: A student picks up the spindle roughing gouge to use on a bowl blank mounted on a faceplate. What do you do?

Phase 3: Edge Assessment (10 minutes)

1. Examine each tool edge with the loupe.
2. Perform the thumbnail test (gently drag the edge across a thumbnail—a sharp edge catches; a dull edge slides).
3. Perform the end-grain test (slice across end grain of a softwood scrap—a sharp tool leaves a clean, shiny surface).
4. Categorize each tool as: sharp, needs honing, or needs grinding.

Discussion Points

• Why are gouges the most versatile tools in the set?
• What makes the skew chisel the most difficult tool for beginners?
• Why is the SRG restriction on faceplate work a life-safety rule, not just a preference?
• How does steel type affect how often you need to sharpen?

Expected Outcomes

• Students correctly identify all tools by name and type
• Students select appropriate tools for each scenario
• Students can assess edge sharpness using multiple methods
• Students articulate the SRG safety restriction with understanding of the physics

Assessment Rubric

Criteria	Excellent (4)	Proficient (3)	Developing (2)	Beginning (1)
Identification	All tools correctly identified with construction details	All tools named, minor detail errors	2-3 tools confused	Cannot identify major tool types
Scenario Selection	All scenarios correct with reasoning	1 error, self-corrected	2-3 errors	Incorrect or unsafe selections
Edge Assessment	Accurately categorizes all edges	1-2 assessment errors	Inconsistent assessment method	Cannot determine sharpness
Safety Awareness	Immediately identifies SRG danger, explains physics	Identifies danger, basic explanation	Hesitates on SRG scenario	Does not recognize the hazard

Safety Considerations

• Handle all tools by the handle, never the blade
• When passing tools, offer the handle first
• Keep tools pointed away from body when examining edges
• The thumbnail test should be extremely light—do not press hard enough to cut skin
