I'm putting on a brand new set of vintage kluson tuners but the bushings are bigger than the stock holes. I read that the best tool to use is a reamer, but the guy at the hardware store didn't really know what I was talking about and I got a feeling they didn't have them. Now I'm kinda stuck because I can't find a reamer, only online where they are $60+. Has anyone had any luck with using a regular drill bit? I'm skeptical because I'm afraid I'll mess up my headstock.
