Crank Handle Turn

How it's made

Source

a hand-driven winch; dry pivot stick-slip produces a bending 430–1100 Hz squeak with weaker second/third harmonics and rubbed broadband energy, rather than a steady motor tone.

Body

gear teeth excite damped steel bands near 720, 1730 and 3190 Hz (25–85 ms); a low bracket resonance at 190–340 Hz adds weight. Size scales all these frequencies together.

Envelope

1–3 complete turns per 4 s; two unequal, smooth pressure lobes per turn bend the squeak and friction level. Twelve teeth per turn arrive unevenly as the hand accelerates and slows.

Layers

narrow friction harmonics sit above a 250–3300 Hz rubbing bed, with 2 ms tooth attacks and short metallic tails. The source is close, mono and dry, without room reverberation.

Variation

seeded tooth strengths/tuning and slow friction wander soften repetition; the tooth timing pattern repeats each turn. Wear controls squeal and roughness; load adds bracket weight.

Presets

an old winch, a slow heavily loaded drum, a lubricated mechanism and a small brisk crank.
