Just watched the tool probe miss the holder and salute the ceiling fan

Man, that's the worst kind of scare. Everyone worries about the tool or the holder, but nobody talks about the hidden shock load through the whole spindle. That little crash could have tweaked bearings you won't feel for months, and the fan blade impact sends vibrations through the whole machine frame. It's a slow death sentence for precision, not just a funny oops moment.

Exactly, that vibration shock is the silent killer. Spindle bearings are meant to handle perfect vertical loads, not get whacked sideways by a fan blade. Each little hit like that makes the preload just a tiny bit off, and you will never see it coming until your finish goes to hell on some critical part. It is not one big failure, but a hundred small ones adding up where the machine just gets a little sloppier each month. The scary part is you would never know until it is too late to just tweak it back.

Fan blades hitting at specific frequencies can set up a harmonic in the spindle housing. Over time, this doesn't just affect bearings but can warp the housing itself, making true alignment impossible. I've heard of shops where they had to scrap entire spindles because the wear patterns were too complex to fix. It's one of those things that makes you paranoid about every little noise, lol.
