This was a viola where the pegs were originally lined up incorrectly. The "D" and the "G" strings rubbed on the other pegs. To correct this problem, the "A" peg was moved down 2mm and the "D" peg was moved up 2mm. First the boxwood bushings were fitted, then the outside faces were carefully made flush with the peg box. Then the new holes were drilled and the pegs were fitted. Then there was a slight amount of varnish touch up to make the boxwood a matching color to the original varnish.

Here is a violin that had a very old style friction peg, plus it had previously had geared pegs installed. The holes needed to be bushed with a spiral bushing and then some new pegs installed.
