lol, R850 to sandpaper a few frets...maybe 30 minutes work. ?
You speak from ignorance there...
Tools & consumables: Radiused sanding blocks; special adhesive sandpaper; specialised crowning and fret end files; straightedges; board protection; scratch removal and polishing materials; nut files; and two sets of strings.
Time... adjust truss, allow to settle, file down frets, recrown frets (one by one), shape fretends, restring with new strings, tune, adjust truss rod, allow to settle, spot file and crown high spots, recut nut, remove strings, smooth and polish frets, oil board, restring with new set of strings and tune.
