Well, thanks for sticking with me on this. It may not have much
practical value -- I'm not planning on installing $300 bearings where
$8 units will do, but it's good exercise.

I don't know if I've ever touched a $300 bearing. Well, maybe -- I've
handled some all-ceramic bearing sets, and the ones with ceramic races, as
well as ceramic balls, cost like crazy. Or they did.

They still do. But even a pair of Bridgeport spindle bearings costs
close to $300.
