What do you guys think about strictly bolt-on necks with no mortise/tenon? Do you have to inset the heel on a bolt-on or does it sit right on top of the sides? Has anyone used the kit from luthiers cool tools? Thanks a bunch |

Right on top of the sides is fine you do not need to inlet anything. My only dislike about a true butt joint bolt-on is that you have the oversize tolerance of the bolt hole to deal with. This allows the neck to yaw a tad until the bolts are drawn tight. This requires that you continually check and adjust alignment till you have the neck torque down. Structurally it is perfectly fine. |

Yup, just butt it up against the sides. I've used this for years. |

Hi Edward, I have constructed a couple of guitars based on the information from RM Mottola. Really straight forward and a real sinch to fit and do a reset when the time comes. See this link http://liutaiomottola.com/construction/Bolton.htm Dave |

So its best to keep the heel beefy for the inserts? Also is it safe to use a smaller neck block? |

I can't answer about the neck block, and I don't use this design, but I'd recommend installing a dowel through the heel, from the fingerboard to the heel cap. This strenghtens the heel and gives the inserts something to thread into that's not end grain. |

That sounds like a good idea, some use that in a tenon/mortise as well right? |

I've done only 12 butt-joint bolt ons. The first few were trouble finding workable dimensions. The rest have been fine. You don't need a particularly big heel. Enough for a half inch thread or so. I wouldn't skimp on the block, though. I learned that the hard way, too. The joint is strong with a thinner block, but the top dips without that support. I'm trying to figure out how to repair it. |
