It took a while but here is another report about what has happened since te last post.
The radius of the fingerboard is applied (9.5 "). The position dots are in place (pearl). The headstock is brought to te right thickness. The transition from the head to the neck is applied using rasp, file and sandpaper.
The front and back of the body are sanded flat. The side of the body is nicely squared with the router . For this purpose, the template used as a guide. After some sanding the traces of the routing are no longer visible.
