To; All builders using bolt on necks, It has come to our attention that there are quite a few of you who are gluing in your M&T joints on your bolt on necks. Please refrain from doing this. Not only is this completely unnecessary, it negates the only main virtue of bolt on construction (necks that can be reset quickly and easily). This problem is compounded by the fact that most have never given proper consideration to headspacing the joint properly to allow for removal of one fret and the injection of steam to soften the glue. If you wish to glue your necks please learn to fashion and fit a proper dovetail, otherwise just bolt it on. Thank you, The repair dept. |

Yup. Like tightening up the lug nuts on your wheels, then welding them all in place just to be sure. |

To: The repair Dept. RE: Glueing bolt on necks. You may or may not be pleased to know that this station does not use ANY glue when bolting on a neck. None on the mortise and tenon and none on the fingerboard extension. Awaiting further instruction. Build station TOM HLA EDN |

If I understand it Martin uses one bolt as a clamp and leave it in rather than removing the bolt/clamp. This station uses 2 bolts no glue, we have used glue on the finger board extensions. We will discontinue this practice as directed. |

I don't get it. Surely if bolted on is good, bolted and glued must be better? |

We here in this factory will never use glue for the neck joint except for actual dovetail joints. And we don't do dovetail joints. |

Mike, I think they are called barrel nuts! |

Thanks Robbie!! That's it. Thought they were externally threaded. Wayne, I thought that too. Search McMaster for barrel nuts. Nothing like the concept. |

Sent from my iPhone using Tapatalk I hope you are using HHG for this because it is obviously superior for tone in string to saddle joints. I have a slightly different approach. I glue in my bridge pins to keep the strings on at the bridge. I weld them onto the tuner posts but I'm sure that is what everyone does. I do go the extra mile and weld the gears once I get it tuned to pitch that way I never have to mess with tuning again!

I've eschewed the mechanical weld of tuned strings for liquid nails. Occasionally, I have found that the tuning drifts. So it's nice knowing that solvents and a heat gun can help me adjust when guitars come back for work. |

In a related note I had a customer bring in a guitar for a string change. Turns out his bridge pins were a little loose, so he had glued them in......... |
