I've been avoiding working on the neck, i don't have any fancy templates to radius the fretboard or carve the back of the neck, but i can't let that stop me, I think I've figured out how to do that without jigs.
I'm using an unusual home-built truss rod in this neck, it seems to work on the bench and I cannot see why it would not work to adjust a neck (we'll see won't we?). I routed the channel for the truss rod, a little thicker than needed at 1/4", but thats all I could do, the truss rod itself is 3/16", but I see lots of people with the same issues, and the truss rods do seem to work even if there is a little lateral slop in the channel. After routing the channel I bolted on the neck template and routed the outside dimensions - only a little tear-out and burnout in places, but actually nothing disastrous that cannot be sanded out. I better keep praying to the router gods and making my sacrifices to them, they seem to like me.
The last pic here shows the truss rod installed in the shaped neck. A little more sloppy than I was shooting for, but I can brace any gaps with scrap wood inside while still allowing the rod to flex. Overall I am happy for a first build!
