Anyone else get really tense when drilling out that huge 1/2” hole in a beautiful finished (acoustic)guitar? Sent from my iPhone using Tapatalk |

For the jack you mean? Get a step drill bit and the proper reamer and you will never worry again. |

Done it many times and have the correct tool(s). Most endpin units are actually designed for a 15/32” hole, so that 1/2” is looser than ideal. Stewmac carries the ideal reamer for the job. Expensive. I waited until it was 15% off. Still expensive. The other issue with installing endpin jacks is that the tail block may be too thick and require a counterbore. Various ways to handle this. You’ll find posts on the forum about modifying a spade bit as a counterbore, but the slickest solution is a rear spot facer. I drill out the original endpin hole to 5/16” to accommodate the pilot shaft (indexed for correct depth) for the 7/8” spot racer and prepare the face. Then the Stewmac reamer to make the 15/32” hole. In a busy shop, these pay for themselves in no time. Sent from my iPad using Tapatalk |

As Tim said, get the reamer and you'll never worry. Expensive, yes, it takes a couple of installations to amortize it but not splitting a D-35 makes it worth while. And like Tim also mentioned, I had one guitar with a very thick end block and made a pull counter sink bit out of a spade bit. Mine is home made, kind of mickey mouse but worked fine. |

+1 for step drill. You need the one that is long and has about 1/2" facets. Stop at 7/16" and do.the rest with the StewMac reamer. |

Actually, if you’re using the Stewmac reamer, there’s no need for a step drill bit. The reamer is very sharp and does a quick enlarging an existing endpin hole, or you drill a 5/16” pilot for guitars without an endpin. Sent from my iPad using Tapatalk |

15/32" is 11.901 mm. Metric step drill to 12 mm cost = $15 or less Stewmac reamer cost = $87 Never seen the need for the reamer myself, considering I had the step drill anyway.... |

A step drill from Harbor Freight costs less than $10 and does the lion's share of cutting. Plus, you can start with a 3/16" pilot hole drilled with a twist drill (to minimize tearout on inside block). I figure my StewMac reamer will last much longer by shifting most of the drilling to a disposable cutting tool. Also, many are using Baltic Birch as a tail block and the glue used is not especially kind to cutting tools. |

I drill on the drillpress with the LeeValley brad point bits before the back and top are installed. Works well for me. |

I still use a step bit with the reamer. I drill the end pin screw hole out with a 1/4in bit then step up to 7/16th and finish with the reamer. |
