Spindle Making

Part of Textiles and Weaving

The drop spindle is humanity’s oldest spinning tool — a weighted stick that twists fiber into yarn through gravity and rotation. Carving one correctly determines the quality of every thread you produce.

For most of human textile history, the drop spindle was the only spinning technology that existed. The spinning wheel was not invented until roughly 500 CE in India, and did not reach Europe until the medieval period. Every length of thread in ancient Egypt, Greece, Rome, and pre-Columbian America was spun on a hand spindle. A skilled spinner with a good drop spindle can produce thread fast enough to keep a weaver supplied — and two spinners can outpace one weaver even on a simple frame loom.

The spindle seems primitive. It is a stick with a weight. But its dimensions, balance, and whorl placement have been refined over thousands of years of practice into a form that works with remarkable efficiency. A poorly made spindle fights the spinner; a well-made spindle almost spins itself.

How a Drop Spindle Works

The spindle shaft is a tapered rod. The whorl (the disk weight) adds rotational inertia, keeping the spindle spinning longer after each initial spin. The hook at the top holds the developing yarn while the spindle hangs freely and rotates, twisting the drafted fiber drawn down by the spinner’s hands.

As the spindle rotates, it imparts twist to the fiber above it. The spinner controls how much fiber is allowed to twist by how loosely or tightly they hold the fiber supply (called the roving or top). When enough yarn accumulates, it is wound onto the shaft and spinning resumes.

Two types of twist:

• Z-twist: Spindle spun clockwise when viewed from above. The yarn twists like the center of a Z. Most common for single-ply yarn.
• S-twist: Spindle spun counterclockwise. Used for plying (twisting two or more Z-twisted singles together) to produce stronger, balanced yarn.

Wood Selection for the Shaft

The shaft must be:

• Straight-grained wood — no swirling grain that causes warping or splitting under the load
• Dense enough to be smoothed to a fine taper without crumbling
• Hard enough to resist wear at the hook end and whorl seat

Best species:

Wood	Properties	Notes
Birch	Straight grain, smooth finish, moderate hardness	Excellent choice, widely available
Apple or cherry	Dense, takes fine taper well, beautiful finish	Top choice for fine spindles
Ash	Strong, straight, slightly flexible	Good for larger spindles
Maple	Hard, very smooth finish	Excellent but harder to carve
Hazel	Straight shoots, easy carving	Shoots need 1 year drying
Yew	Exceptional, very hard	Avoid sapwood; use heartwood only

Avoid pine and other softwoods — they are too soft to maintain a smooth taper and compress under the whorl.

Seasoning: Use wood that has been drying for at least 6-12 months. Green wood will warp as it dries, ruining the straightness essential for smooth spinning. If you must work with greener wood, rough-shape slightly oversized and allow to finish drying before final shaping.

Shaft Dimensions

Shaft component	Dimension
Total length	25-35 cm (shorter = faster spin, shorter yarn before winding; longer = more yarn storage)
Diameter at widest point (below whorl)	8-12 mm
Diameter at tip (top, above whorl)	4-6 mm
Diameter at base (bottom tip)	3-5 mm
Whorl position from top	3-5 cm from top (high whorl) or 3-5 cm from bottom (low whorl)

High whorl vs. low whorl:

• High whorl (whorl near top): Better for fine fiber like flax. The long shaft below provides more yarn storage. The yarn travels down and up around the shaft to the hook.
• Low whorl (whorl near bottom): Better for wool and coarser fiber. Simpler to use for beginners. Yarn winds directly onto shaft above the whorl.

Carving the Shaft

Tools needed: A sharp knife (a single good knife is sufficient), sandpaper or smooth stone for finishing.

1. Select your blank: Split a piece of straight-grained wood to roughly 15 mm square cross-section and 35 cm long. Split rather than saw to preserve grain continuity.

2. Rough octagon: Carve all four corners off the square blank to create an eight-sided profile. Work with the grain, not against it. This prevents the flat-siding that makes a spindle wobble.

3. Taper from center outward: The widest point of the shaft should be roughly 8-10 cm below the intended whorl seat (for low whorl) or at center for high whorl. Taper toward both ends.

4. Refine to round: Work progressively around the shaft, removing the ridges of the octagon. Check for straightness constantly by holding the shaft at eye level and rotating slowly. Any bow or flat spot will cause wobble.

5. Whorl seat: For a removable whorl, cut a gentle step — the shaft narrows by 1-2 mm over a 2 cm length to form a shoulder the whorl sits against. The fit should be snug but not force-fitted, as wood swells with humidity.

6. The hook (top tip): Carve a small notch around the top tip, or cut a groove. The yarn loop that holds the developing yarn sits in this notch. The notch must be smooth — any roughness will catch and break the yarn. Some spindles use a bent wire hook; carved notch is simpler and fully functional.

7. Finishing: Sand progressively through grits (rough stone → fine stone → smooth leather strop). The shaft must be as smooth as glass. Any rough spots cause the yarn to catch or drag. Rub with beeswax or tallow for final finish.

Making the Whorl

The whorl is the weight that keeps the spindle spinning. Its mass and diameter determine spin characteristics.

Whorl physics:

• Heavier whorl: More rotational inertia — spins longer after initial spin. Good for coarse fiber, large yarn.
• Lighter whorl: Loses momentum faster — requires more frequent spinning. Better for fine fiber and thin yarn.
• Larger diameter: More inertia per unit mass. Spins longer but starts more slowly.
• Smaller diameter: Starts and stops quickly. Better for fine, controlled spinning.

Weight guide by fiber type:

Fiber type	Whorl weight	Whorl diameter
Fine flax, silk	10-20 g	40-55 mm
Wool (fine)	20-35 g	50-65 mm
Wool (medium)	30-50 g	55-70 mm
Hemp, coarse fiber	40-80 g	60-80 mm

Whorl materials:

Wood: Cut a disk from dense hardwood, 8-15 mm thick. Drill a center hole sized to fit the shaft snugly. Refine hole with a round file or knife point until the fit is firm.

Clay: Form a disk from clay, punch the center hole with the shaft itself (ensuring exact fit), and fire hard. Clay whorls crack if the hole is off-center — press carefully. Fire temperature: 600-900°C in a wood fire is sufficient.

Stone: Disk-shaped river stones occasionally have natural holes (used as-is) or can be drilled with a harder stone point and patience. Stone whorls are extremely durable.

Bone: Flat bone sections (shoulder blades, large rib sections) can be cut to disk shape and drilled. Bone whorls are light for their size — good for fine spinning.

Testing whorl balance: Fit the whorl onto the shaft and spin the spindle freely on a flat surface. It should spin smoothly without wobbling. If it wobbles, the whorl hole is not centered or the whorl disk is not uniform thickness. Correct by filing or shaving the heavy side of the whorl.

The Notch Hook

The hook holds the leader yarn (the initial thread that connects the fiber supply to the spindle) and keeps developing yarn from slipping off as the spindle drops and rotates.

Options:

1. Carved notch: A V-cut groove around the tip. Simple and never breaks.
2. Bent wire hook: A piece of wire (copper, iron, even a bent nail) pushed into a hole drilled in the tip. Allows easy yarn removal. Secure with a drop of pine resin glue.
3. Groove and peg: A groove around the neck with a small peg or knob to catch the loop. Common in Central Asian designs.

The notch should catch the yarn loop securely when spinning but release it easily when you wind on yarn. Test with actual yarn before declaring the spindle finished.

Finishing and Testing

A finished spindle should:

• Balance the spindle at the whorl — hang from a thread at the whorl and the shaft should hang approximately horizontal
• Spin for at least 30-45 seconds when given a good initial spin (top spinners) or 20-30 seconds (bottom spinners) with a light touch
• Show no wobble when spinning freely
• Feel smooth throughout its entire surface

Test with actual fiber before using for production. Spin a small amount of prepared wool or flax and assess how the spindle performs. A spindle that drops too fast needs a heavier whorl. One that drifts sideways needs a straighter shaft or better-balanced whorl.

Making Multiple Spindles

A fiber-producing settlement needs multiple spindles — typically 3-5 spinners can supply one weaver. Each spinner needs at least one spindle, and having a spare is essential (spindles drop and break).

Production batch method:

1. Split multiple shaft blanks at once from the same piece of wood for consistency.
2. Shape all shafts to the same dimensions using a simple gauge (a drilled block of wood with the target diameter hole).
3. Make all whorls from the same batch of clay, weighed before firing for consistency.
4. Fire all clay whorls together in one burn.

A skilled woodcarver can produce 3-4 spindles per day once the motions are practiced. A settlement of 20 people with 5 spinners needs 10-15 spindles (working set plus spares).

The drop spindle is not a stepping stone to the spinning wheel — it remains useful wherever portability matters (field work, tending animals, traveling) and for fine-yarn production where wheel spinning is less controlled. Learn the spindle first; it teaches the fundamentals of twist, tension, and drafting that all other spinning methods build on.
