Describing setting the neck is kind of difficult, so hopefully my pictures will help.
Before setting the neck, I drilled through the neck block to fit the neck attachment bolt.
2 adjustments needed to be made - the side-to-side adjustment of the neck, as well as the angle of the neck front to back (which controls the action of the finished guitar).
The whole process took me about 4 hours! All this work means that the guitar should play good when its put together!
After setting the neck, I moved on to fretting the fingerboard......
