You’re right it does not... more commonly the adjusting nut is left at the end of the neck either at the nut or the neck body joint. I think this way should work—I’ve seen it in at least one factory Takamine.Dave M wrote: ↑Thu Nov 16, 2017 9:24 pmAndy I may be misinterpreting here but the truss rod adjusting nut does not need to be near the soundhole. A reasonably long allen key can be used to reach the truss rod adjustment nut that is only a bit further forward than the neck body join...?
I too always put a truss rod in classical builds, though I don't use the Spanish neck body joint. (I do tend to follow Trevor Gore's design ideas.)
You drill small holes through the harmonic bars to give the Allen key a path to reach the truss rod adjusting but... pretty much what you have done but the rod doesn’t come out as much. This way works well especially if you are constructing the guitar as an integral unit and not with a neck joint of some sort. I do like the easy access..Andy Culpepper wrote: ↑Fri Nov 17, 2017 12:33 amHmm yeah I probably could have put the end at the first harmonic bar. I don't know about all the way recessed into the heel block because it seems like the harmonic bar would be blocking it there. It's pretty close to the foot. Might have worked though. Maybe next time. I did want to make it pretty user-friendly and accessible although I have a feeling he'll probably never need to adjust it. Most of the pictures I found online had it this way, I think because you can adjust it under string tension.
We did not want the adjustment at the nut end, that would have been much easier
As a clarifying note, all Hill and New World Guitars as a standard have had double acting truss rods installed since 2000. We started doing this in 1995, in the Master Series; burying them where they could not be seen or disparaged by the trussrod doubters. Eventually, with time, as they have become more socially acceptable, we exposed the adjusting nut at the end of the fingerboard so they are more easily accessed.Jacek A.

Here is what Kenny says on the truss rod in his guitars (text and illustrations)

and I thought that it may be of help.
