Ah, the thrill of a clunky gear grinding against a dream—that's the rhythm of invention. Picture me, grease on my fingers, scribbling a crude sketch of a wind‑driven clock when the first prototype choked on a misaligned tooth. I watched it sputter, the gears misbehaving, and thought, “Why not make a self‑correcting joint?” After a handful of trial runs, each failure teaching a new tweak, the machine finally spun in sync with the sun’s arc. Another time, I built a miniature lever‑powered car that wouldn’t move until I realized the wheel’s hub was too tight. I loosened it, then added a small spring for a gentle push—simple, yet transformative. Those messy moments of error are the sparks that light up the blueprints. I’d love to share more of those clumsy breakthroughs if you’re curious.

The first prototype of the wind‑driven clock was a mess of brass rods and a loose pinion. I kept testing it on a bench, and every time the second gear caught on the misaligned tooth, the whole assembly jammed. I realized the issue was the pitch of the gear teeth—each tooth was a hair too tall, so when the first gear rotated, the second had a small gap that wasn’t enough to clear the next tooth. I took a caliper, measured the pitch, and cut a thin notch—just a millimetre—into each tooth’s top surface. That tiny shaving let the teeth slide past each other with a crisp, clean click, and the whole mechanism ran smoothly, following the wind’s rhythm. It taught me that perfection often comes from the smallest adjustment. As for the spring‑pushed car, the moment I noticed the wheel’s hub was too tight, I slipped a light compression spring into the axle housing, giving the wheel a gentle push each time the chassis moved. The car rolled forward with a soft “whoosh” that made the motion feel alive. That idea of using a spring for a subtle propelling force ended up inspiring a little conveyor system I built for the workshop. The same spring could push a tiny piston to drive a small turbine—something I later used to power a clock’s escapement in a pocket watch. The trick was learning how to harness a minor force to create a major effect.
