In the past, i drilled two different diameter holes for these, the 25/64" on the back of the peghead and about 8mm on the front. Is this necessary? Can I just drill through at 25/64"? Or is it better to snug fit the locking screw? Mike |

Mike: Have never used Grover closed tuners but have used Shallers and Gotoh. For closed backs I don't drill a stepped hole but the extra support would not hurt in my opinion. Tom |

Keep step drilling, you want support for both the body of the tuner and the bushing. |

Yup, step drilling is the way to go. It prevents finish delam around the top holes if the grommets loosen up. |

Hmmm. Ok. Makes sense. The way I step drill is to use a small pilot hole all the way through. Then that centers up the steps. Sound good? I was more concerned about torquing of the peg which could hurt tuning. Mike |

FWIW, I have always drilled through with a 10mm bit and never had an issue. I guess drilling an 8mm hole for the top portion makes sense, I'm not sure it is required. |
