Slide 001: Wood Turning Tool Types and Anatomy¶
Slide Visual¶
Slide Overview¶
This slide introduces the major categories of wood turning tools, their physical construction, and the specific applications for each tool type in spindle and faceplate turning.
Instruction Notes¶
Tool Construction¶
All wood turning tools share a common anatomy: blade (the steel cutting portion), ferrule (metal collar preventing handle splitting), and handle (typically hardwood, 10-16" long for leverage). Tools attach to handles via either a tang (pointed rod driven into the handle) or a socket (hollow receiver the handle inserts into). Socket construction is stronger and preferred for heavy-duty tools.
Primary Tool Categories¶
Gouges — The workhorses of turning: - Spindle Roughing Gouge (SRG): 1-1/4" to 2" wide, shallow U-flute, 45° grind. Used ONLY for spindle turning to rough square stock to round. NEVER use on faceplate work—the tang connection cannot withstand lateral forces. - Spindle Gouge (Detail Gouge): 3/8" to 3/4" wide, shallow flute, fingernail grind (30-40°). Used for coves, beads, and detail work on spindles. - Bowl Gouge: 3/8" to 5/8" wide, deep parabolic flute, swept-back grind (45-65°). The primary tool for bowl and faceplate turning. Heavier cross-section handles lateral forces safely.
Skew Chisel: Flat blade with an angled cutting edge (typically 70° skew angle). Available in oval or rectangular cross-sections. The premier finishing tool for spindle work—produces the smoothest surface directly from the tool.
Parting Tool: Narrow (1/8" to 3/16"), deep blade used perpendicular to the workpiece for establishing diameters, creating tenons, and separating finished pieces. Diamond-profile parting tools resist binding in deep cuts.
Scrapers: Flat tools with a burr edge used below center for finishing cuts. Types include: - Round-nose: Bowl interiors - Square-end: Flat surfaces - Diamond-point: Corners and detail areas - Negative-rake: Safer alternative with a 15° negative top angle
Steel Grades¶
| Steel | Hardness (HRC) | Edge Life | Heat Resistance | Cost |
|---|---|---|---|---|
| Carbon Steel | 58-60 | Short | Poor (500°F) | Low |
| M2 HSS | 62-64 | Good | Good (1100°F) | Moderate |
| M42 HSS | 65-67 | Very Good | Very Good | Moderate-High |
| PM HSS (CPM-10V) | 62-64 | Excellent | Good | High |
Key Talking Points¶
- Never use a spindle roughing gouge on faceplate work—this is a critical safety rule
- Sharp tools are safer than dull tools—they require less force and give more control
- Start with three tools: roughing gouge, spindle gouge, and parting tool
- Tool handle length provides leverage—longer handles for larger work
Learning Objectives (Concept Check)¶
- Can students identify each tool type by sight?
- Can students explain why SRGs are restricted to spindle work?
- Do students understand the difference between tang and socket construction?
