It certainly isn't uncommon to see crazy repairs and modifications come through the shop. I often find myself scratching my head trying to figure out just how some of these seemed reasonable to anybody. I hope this person was stranded in an isolated location and only had one set of replacement tuners but they were probably just too lazy to go find the correct replacements. Of course they couldn't be too lazy if they chiseled out all that wood with a dull tool!
