Build a Guitar Neck

 
 
 
Now that we have the basic shape I lay the 2way truss rod in place and 
mark the position. 2way truss rods are easy to install as they only need a 
straight slot. They don't need a tapered slot like a one way rod.
The slot for most 2way rods needs to be 1/4" wide and 3-8" deep. Some 
rods require a little wider slot at the top to accomodate the adjuster cover.
I just widen it slightly with a sharp chisel.
 
 
 
This is a jig I made for routing the truss rod slot. Its just a board with a 
1/2" slot in it. This is a view of the back showing how the neck is held in 
place while routing. The picture below shows the router setup for cutting 
the slot.
 
 
 
 
This is the router in the slotting jig. The neck was bolted in the jig from
the back. The center line drawn on the neck previously is centered in the 
jigs slot. To start, set the router in the jig (turned off) with the router bit
on the line you drew for the nut. mark the position of the router on the jig. 
This will tell you when you are routing where to stop. You don't need a 
mark at the heel end as there is a stop built into the jig. Basically it's the 
end of the slot. There is no stop at the top because some necks are longer. 
That is why we marked the jig at the top.
 
 
 
 
This is the router setup. It is just a 1/4" straight router bit. The base of 
the router has a bearing installed that matches the slot in the jig. 
The bearing could be any size as long as it is larger than the 1/4" router 
bit and fits without any slop in the jigs slot.
 
 
 
 
Here the truss rod is installed in the slot we cut from the previous step. Again
notice how I had to enlarge the slot for the cover on the rod. At this point the 
truss rod is flush or slightly recessed so as not to push up the fret board we 
will install later.
At this point you can glue on the fret board if you have one. If your going to 
make your own keep reading.
