I'm surprised that the spindle nose wasn't polished up on the outside ( 6.17 ), I know it's only cosmetic, but it would finish of the job. I'm also surprised that the bearings were just slide on the spindle ( 5.46 ), I thought that they'd be a press fit.
No good practices seen here. Cleanliness is the most important thing when working with those utterly expensive spindlebearings. Every hobbyist would do it as shown, for a professional spindle repair this is nuts. Sorry
