Still kind of chicken about running a high speed spindle (a Bosch
router) without coolant. So my question is, do people use coolant at,
say, 10k RPM? 20k? I would say the OD of the spindle nut is 1 inch.

Air only. Maybe a mist..but definately Air only

I bet. At 10,000 rpm, it will be hard to keep the tool wet, even if flooded.

I actually fixed up my air mister. And I have a question, actually two

1) How bad is vegetable air mist oil for lungs

Not great. Depends on your lungs and how well they get rid of oil and
other debris

2) Just how much mess will it make with chips flying all over the
place?

Slightly less than oil/coolant soaked chips flying all over the place.
It sweeps up easier.
