It appears that my LMI fretting templates make the nut-end of the fingerboard closer to the first fret than it should be by half the width of the tablesaw blade I use. I just busted out the calipers, and the distance between the nut "groove" and 1st fret "groove", center to center, is exactly what the distance between the two should be on the actual FB. This does not account for the width of the saw kerf. For slots where frets will end up, this is not a problem because the center of the fret is still above the center of the slot. But for the end of the FB, an additional 0.0115" is taken off. So essentially I have been compensating my nut without knowing it, although I don't actually take that into consideration when compensating the saddle, so it's not beneficial. Does this make sense, or am I off my proverbial rocker? |

When I referred to the "grooves", I mean the notches in the template. |

That's exactly how Taylor's nuts ended up being compensated. Quite by mistake, but they liked it and ended up sticking with it. |

Thanks, David. I think I might be ok with it too. I'm not exactly sure how to account for yet though when it comes time to intonate. I'm thinking something with balancing the intonation between the open and 12th fret notes, and other fretted notes, like 1 and 13 or something. Any idea how they do it? |

Mike, read Mike Doolin's article in the latest GAL magazine. There's a lot of good info there including a good reason why taking half a fret slot off the nut end is a good place to start. I find that taking another .010" off the bass end helps too. |

Amazing, I glue a .010 ebony shim on all my boards. And they sound great..... Of course, I cut my own now and don't have that built in mistake.... (knock over proverbial can of worms) Hey if Taylor and Doolin do it, it must be fine.... But I've actually measured all four Taylors I purchased. |

Thanks, Kent. I will do that. Bruce, do you mean that you make the board longer? For why? |
