Going Train Calculator: Clock Gear Ratios and Speeds | FIRGELLI
Calculate speeds and barrel period through four clock-train gear stages. Explore direction reversals and distinguish gear ratios from escapement timing.
Karrusel Watch Mechanism and Separate Static-Load Calculator | FIRGELLI
See an illustrative rotating watch carriage and oscillating balance. A separate weight-and-moment calculator demonstrates general statics; it does not predict watch loads or timekeeping.
Dead-beat Clock Escapement Calculator | FIRGELLI
Watch a dead-beat clock escapement lock and release. Calculate ideal pendulum period, beat rate, escape-wheel speed and pendulum-bob travel.
