Student Material 001: Spindle Turning Techniques Quick Reference¶
Material ID: U7M3-MAT-001 Purpose: Quick reference for spindle turning shapes, tool selection, and finishing procedures
Fundamental Spindle Shapes¶
| Shape | Tool | Technique Summary | Direction |
|---|---|---|---|
| Cylinder | SRG | Overlapping passes, bevel riding | Along length |
| Taper | Skew or gouge | Progressive passes removing more at one end | Large to small |
| Cove | Spindle gouge | Start at rim, roll gouge to bottom; cut from both sides | Rim to center |
| Bead | Skew chisel | Define borders with V-cut, roll from peak to valley | Peak to valley |
| V-Cut | Skew (long point) | Push straight in perpendicular to axis | Perpendicular entry |
| Fillet | Parting tool/skew | Flat horizontal band between features | Perpendicular |
| Pommel | Skew/parting tool | Transition from square to round section | Careful shoulder cut |
Cutting Direction Rule¶
Always cut DOWNHILL: from larger diameter toward smaller diameter.
This means: - Coves: cut from the rim (large) down to the bottom (small) - Beads: cut from the peak (large) down to the valley (small) - Tapers: cut from the thick end toward the thin end - General rule: if the surface finish tears, you are cutting uphill
Sanding Grit Progression¶
| Step | Grit | Speed | Method |
|---|---|---|---|
| 1 | 120-150 | 500 RPM | Power sand with folded pad |
| 2 | 180 | 500 RPM | Power sand |
| 3 | 220 | 500 RPM | Power sand |
| 4 | 320 | 500 RPM | Power sand |
| 5 | 320 | Lathe off | Hand sand WITH the grain |
| 6 | 400 (optional) | Lathe off | Hand sand WITH the grain |
Tips: - Remove tool rest before sanding or move it below centerline - Never wrap sandpaper around fingers - Clean surface between grits with compressed air - Sand through each grit completely before moving to the next
Finish Application Guide¶
| Finish Type | Application Method | Speed | Coats | Best For |
|---|---|---|---|---|
| Danish Oil | Paper towel pad | 300 RPM | 2-3 | Functional items, natural look |
| Friction Polish | Cloth pad, firm pressure | 1500+ RPM | 1 | Decorative items, high gloss |
| Paste Wax | Wax stick + buff cloth | 800 RPM | 1-2 | Top coat over oil, low sheen |
| CA (Super Glue) | Apply thin, accelerator between | 800 RPM | 5-10 | Pens, bottle stoppers, high durability |
| Lacquer | Spray (lathe off) | N/A | 3-4 | Professional finish, requires ventilation |
Common Catches and Prevention¶
| Catch Type | Cause | Prevention |
|---|---|---|
| Skew dig-in | Leading with long point on planing cut | Keep long point above the workpiece; cut with lower 1/3 of edge |
| Gouge spiral catch | Flute facing wrong direction | Flute always faces direction of cut |
| Scraper grab | Presenting above center | Always present scrapers at or below center |
| Roughing catch | Too deep initial cut on square stock | Start with 1/16" cuts; increase as stock rounds |
Troubleshooting¶
| Problem | Likely Cause | Solution |
|---|---|---|
| Torn grain on cove | Cutting uphill | Reverse cut direction; cut rim to center |
| Chatter marks | Tool rest too far; tool overhang | Move tool rest closer; use shorter tool rest |
| Spiral marks | Uneven hand movement | Slow down; maintain consistent feed rate |
| Rough end grain | Dull tool; wrong approach angle | Sharpen; use shear cut at 45° to grain |
