Truss Rod and Neck Joint

Friday, January 2, 2009 0 comments

I have been getting a little bit done over the last week. I wa able to get the truss rod groove cut in the neck. The truss rod provides the stiffness of a metal rod to counter the tension of the strings. The rod that I use is a two way adjustable rod. By turning the nut, you can adjust the bow in the truss rod, and since it is secured in the neck, you are able to adjust the bow, or relief, in the neck.


Here the truss rod is set in the slot.
Using a Safe-T-Planer chucked up in the drill press I am able to put a taper to the neck. You can see a small shim at the headstock end of the neck. The taper is approximately 1/8 inch. The S-T-P will be used again later to get the headstock to proper thickness.




Next it is time to cut the dovetail joint that will connect the neck to the guitar body. I have a pretty cool set up to use a router to do this. The neck is attached to the jig so that the 4 1/2 degree neck angle will be cut in as well.




The same jig with a different template is used to cut the slot in the body for the neck to set into. The router bit is a 14 degree dovetail bit.






Here is the finished neck joint. I have also cut the knotch where the fingerboard extension will sit.
