I built a few of those around 1980 and they are still doing fine. I still own one, and I played another a couple of years ago.
I wouldn't build that way today, though.

So by show of hands, how many folks here have slipped a neck? Was the labor hour count for the work (including touch-ups) roughly equal to the 1.5 - 2.0 hours required for a M&T neck reset?

Also have to agree with Filippo...I don't see the method of attachment of the neck to the neck block as a determining factor in body distortion...I suspect it's more an issue of how stiff the upper portion of the box is. Along with that is a question as to whether what many players prefer in terms of tone (the Martin and Gibson vintage sound) is tied to the method of construction, and whether the sound preferred by some fingerstyle guys is an artifact of stiffer, less compliant construction.


If by slipped you mean lift the back off and adjust the neck by pushing the block back then yes I have and it was a real PIA. I can have a dovetail neck reset in less then half the time. The biggest issue I had in doing that method was preparing the foot since it is at a different angle and must be reset to mate with the back. Of course with a bolt on sometimes you don't even need to take the neck off as you can just floss is with some stiff sand paper.

Ok cool, that's good to know.

BTW have any of you used the wedge method for your Spanish heals? There may be a formal name for this joint but if there is I don't know it. Basically you cut a larger mortise for the sides to slip into the block and then press wedges in to secure them in place. I don't even know if glue would be necessary with this method. I'm thinking of doing that on my next classical build.
