I read that a neck can take a "set" over time and that a truss rod adjustment may not be able to remove all of the relief around the 5-7th frets...seems like I read also that a neck can be heated and clamped to a flat surface to cool to remedy this problem...my question is, how much heat (are we trying to soften the glue enough to let the f/b slide while the neck goes to it's new configuration, then cools?) and won't this wack out the trueness of the f/b? Also, wouldn't the softening of the glue joint allow the f/b to slide out of position side-to-side on the neckshaft? I never meant to get into repair, but people keep "bringing me their sick and infirmed".... Thanks, Larry |

Larry I too would have worries about fixing the set this way. If a neck re-set is in order I would go full bore, remove and re-set. To many things get changed with out compensation for the change in my opinion doing it this way. Quick fixes are seldom good fixes 
Larry I am somewhat in the same boat. I have so many friends that appear at my door wood flu of some sort or another  |

Larry, what type of guitar is it? Sometimes you can get pretty creative with neck straightening, eg.loosen the trussrod, clamp into a backbow and slowly tighten the rod up to tension. I have straightened many necks this way that I thought were hopeless. I never really use heat. Evan |

Take a look at Dan Erlewine's and Brian Gallop's neck re-set video. Very informative. Really worth the price. |

straightening the neck and reseting the neck are different processes for differerent problems and have different results. if a neck has taken a set, i.e. has too much relief and either has no adjustable truss rod, as on a pre '85 martin for instance, or there is not any adjustment left on the rod, then straightening the neck using heat is in order and is a common repair task. if there is an adjustable rod which is difficult to adjust then the process evan describes is a correct way to adjust without running the risk of striping the nut/rod or torqueing the end off. |

Thanks guys for the info...I'll try removing the neck (it's a bolt-on) and clamping it in a backbow and adjusting the rod first (thanks Evan), if that's no good, then with the guy's approval I'll break out my bending blanket and have at it that way... |
