This is probably not news to a lot of you out there, but I've found something to make my builds just a little easier and I thought I would pass it along. In the past, I have always used a drill press to clean out the finish in the post holes after the finish has cured. I just used the same bits that were used initially to create the post holes and bushing counterbore. This always left me more than a little nervous, knowing that things can happen fast with this approach. Well today I saw an old drill press chuck in one of my drawers and thought, Hmmmm? I simply locked the same bits in the chuck and proceeded to clean out the post holes by hand twisting the chuck. It worked like a charm and I felt so much more in control and comfortable. Give it a try if your not completely happy with what you are doing now. |

Bill, that's just what I use and do. Good use of a discarded chuck. |

If you can, put a very tiny chamfer on both faces before cleaning up the holes -- this will prevent possible chipping of the finish. I also clean up the holes by hand -- with either a reamer or drill bit. |

Chucked reamer in a drill press, with some clean-up by hand if needed for bigger lumps of filler or finish. It can be easier to start the clean-out from the back side, as a chamfer is unlikely to cause any issues there. Once that back-side hole is established, the usual scrap ply alignment jig can be used to ream from the face side of the peghead (3/4" plywood with correct diameter hole to take reamer clamped in correct position on drill press table, and a matched diameter dowel stub to force alignment from the rear face of the peghead). |

After going through trying to clean them out I found it's better if you just pack the holes with little pieces of that flexible foam padding like protects TV screens inside boxes, before you spray. |

I love it when you get those... Hmmmmm moments. I like to simply use a reamer too but great idea on that there. I have also found when using drill bits for such things that starting them backwards first sort of chamfers the edge for when you go forward with the cutting action. |

I put a short wood dowel in the tuner hole. I wax it first and flush it top and bottom. Simply press out after finishing and reuse for the next one. Never had any finish issues. |

I do the same thing but I use balsa dowels slightly bigger than the holes. They are easily forced in as the balsa crushes to make a perfect fit. Also very easy to sand flush and to poke out after finishing. |

Been using foam earplugs from the local drug store (buy 1 get 1 free). They have a coating on them so I haven't encountered the problem with lacquer that Chris mentioned. Still use a reamer to dress the edge but not enough to chip the finish. |
