Two things that obsess over fractions of a millimetre: NASA, and a four-person kitchen factory off Junction 22.
One of those you'd expect.
NASA holds aerospace tolerances because a stray fraction ends a mission. We hold 0.1mm because a stray fraction means packers, planing, and a snag list on site. 🔧
Same instinct. Very different budgets.
Barrie spent 40+ years fitting before he founded Slade, so he knew exactly where the millimetres cost you: the join that won't sit flush, the run that drifts across a wall, the door that fouls the one next to it.
That's why the machinery earns the standard. Our BIESSE runs on a strict six-month service schedule to hold that 0.1mm build after build.
We're not launching anything into orbit.
We just want it to fit right the first time ✅
