The way that I do my necks are as follows,
1. Cut the scarf joint with a Japanese pull saw at whatever angle you want.
2. True up the mating surfaces (I use a router and a jig that I made).
3. Glue scarf joint.
4. cut truss rod slot.
5. Thickness fretboard to .25"
6. Cut fret slots.
7. Glue on fretboard
8. Cut the shape of the neck out of the fretboard and neck blank (using a router).
9. Cut headstock shape (also router).
10. Thickness the neck (I use a router with a sled, I raise the neck up a bit at the #1 fret with some veneer to give me the taper that I want running from #1 fret to where i want to start to taper into the heel.
11. Shape back of neck using rasp, cabinet scrapers and sand paper.
12. Radius fretboard.
There are lots of different ways you can go about it, this is just what works for me.
