I have just cut a test neck to body joint dovetail. I made a jig from plywood to hold the pieces and templates cut from 1/4 inch plexiglass. It works! If I could get the templates cut on a CnC machine it would be perfect but I still got a passable dovetail. I used a 1/4 inch straight bit to hog out the material then an 8 degree dovetail bit. It was then fine tuned by hand with a chisel.
The neck and box were just thrown together to test the system and I expected they would be garbage on the first try but I have some usable parts here.
This should make my process much faster now.
It looks weak to me but to each his own. Im assuming it glues it the slot you have cut in the box. I would feel more comfortable if there was a 3 inch screw running through the heal with this design. Of course I dont know what you have on the inside so I cant make a call on it. Good luck with it.
With a short neck and just 3 or 4 it should be OK but I'd make it deeper if I were going to make a six string. It looks well made though and it is the traditional way to mount a neck on a guitar.
The reason that I've used the neck through for CBGs though is that I'm afraid that the box will crush from string pressure. I've seen manufactured guitars crack from string pressure so there's no reason that a CBG wouldn't.
The advantage of that joint is that there is more room inside the box for resonance, which can't be a bad thing.
Exactly what I was thinking as well AG That notch in the box needs to at least be 1 1/2 for me to fell comfortable with it and it does nothing for bracing the box. Through the box is fine but a compromise on both mounts is better. ;)
Just like that, it's too light !! The neck won't suport the strings tension !
It is a ukulele and it is more than strong enough.
Anyway, your points are taken. I was just proud of adding another technique to my bag of tricks. If I were building a six string that would be a whole 'nother ball game likely involving a truss rod as well.
Looks really good to me. You should post a pic of the jig.
Very nicely done, that joint will be more than strong enough.For those worried about the box splitting or deforming - reinforce it.
Cut another two joints today, Why didn't I think of this earlier ?
I found out about the technique from talking to a local luthier. He was showing me a ukulele body and I asked him how the neck attached as I could see it would be difficult at best to put screws in from just the sound hole.
