I am making my second Classical with a Spanish Heel. During my first, I cut the headblock to wide (about 1/64”) and had to shim the sides to close the gap between the sides and heel. I made note of this so I could be sure that I wouldn’t repeat this mistake again. We’ll that failed. Last night while drum sanding my sides, I went too far. I was too concerned with thicknessing to .080”. What do you recommend for shimming or closing the gap at construction time? Or, what is another procedure? Thanks |

Why not do the tapered slot style and put in tapered shims to get that joint perfectly tight? It's structurally better, anyway. |

What is the tapered slot style? |

Doug, First, a disclaimer that I haven't done this myself, but this is the process that I've seen and read about... Cut the heel side of your slot as normal, then enlarge it by making a wedge-shaped cut (doesn't have to be very large) that tapers to the end of your first cut. You can then insert your sides and use the cut-out wedge to hold them flush with your heel (you'll probably have to do some sanding on the wedge to get a tight fit). You'll want the wedge to fit pretty much flush to its original spot in the block. People who have done this a lot can fit the sides and wedge so well that glue isn't needed, but that sure would make me nervous! Make a few practice cuts on some junk wood of the same dimensions as your neck block, and test-fit your sides 'til you're comfortable with the process. Remember, if you're not practicing on scrap, you're practicing on your guitar! |

[QUOTE=CarltonM] Doug, People who have done this a lot can fit the sides and wedge so well that glue isn't needed [/QUOTE] I think most people who build a Spanish heel don't glue the sides in, whether they're using a wedge or not. What do the rest of you do? John |

I do the wedge and glue it in. But no glue between sides and the neck heel. Only glue the wedge to the sides and foot. I forgot to use glue on one, and its held up perfectly with just well fit wedges. |

The slot can be parallel. Just use two wedges to fill the slot. That makes it super easy, because you can just make 1 wedge, then cut it in half lengthwise, and turn one side around. You are guaranteed that the backs will be parallel. |
