| Post subject: | Truss Rod Slot |
Does anyone cut their truss rod slot so that it runs parallel to the bottom of the neck? Is there any advantage/disadvantage to doing this? I'm thinking that most necks have somewhere between .075-.125 taper in them from the neck block to the nut. So why not the slot for the truss rod? Tim |

Tim: Just a few thoughts. It will be a bit more work to do it that way. But it will put the rod a bit deeper in the neck which may or may not be more effective. It also may make it easy to adjust the rod without drilling a hole through the UTB. Tom |

Benedetto in his video talks about having more control with a slightly bowed truss rod slot. The measurements in the book are 7/16" depth from the heel to about halfway up the neck, then gradual bow to 3/8" at the nut. |

Thanks for the replys guys. Tom, Really shouldn't be that much more of a problem doing it that way as I am running it on a mill. As long as I can indicate the top to the dimension I am shooting for it should cut just fine. My feeling is the same as yours in that it will eliminate the hole in the UTB, which I don't put in anyway, and make the access for adjustment easier. Keith, That is one of the things I was hoping to hear. I would also hope that the pressure would be equally ditributed through the neck rather than find the path of least resistance. Thanks Tim |

running the truss rod slot parallel to the spine of the neck will make you cut a tapered shim to fill the slot. Another thing is how the truss rod will react with the wood. . I never did it that way and it may be fine , let us know the results . You will need to be careful of weakening the neck in the areas where the truss rod will push against the neck. I have seen necks crack from thinned areas under the truss rod . |

I make my truss rod slot deeper at the body end than at the nut end. I'm not sure it's any better that way but it hasn't caused any problems either. M |

Just being nosy, but why, Mark? Better leverage? |
