Source: a spring hammer strikes the line-end bell; a hand return drives a toothed rack into its stop. The bell has a 1 ms strike, rack teeth have rounded 0.4 ms attacks and 4-9 ms releases.
Body: the small steel bell rings at 1.7-2.6 kHz with inharmonic modes at 1, 1.48, 2.09 and 2.73. Split modes beat by 3 Hz; upper modes decay in 0.18-0.28 s, the prime in 0.55-0.7 s.
Motion: after a 100 ms hand reaction, 23 rack teeth accelerate then slow over a 0.28-0.55 s return. Band-limited rail friction brightens with carriage velocity; each tooth excites short steel modes.
Stop: a 5 ms collision excites damped 170-1400 Hz frame modes, followed by a softer latch 23 ms later.
Envelope: bell and mechanism overlap naturally; the frame settles within 180 ms of the stop. A final 70 ms fade ends by 1.03 s; no room reverb is added.
Variation: seeded tooth timing, strength and bell tuning; size changes frame mass and bell pitch. Presets cover light portable, heavy office, fast assertive and gentle damped returns.
