making the neck - body mortise

This is most probably the most delicate and difficult thing I´ve made untill now.
There are so many parameters that have to be correct. Strobels book says:
1) the fingerboard is centered over the front centerline.
2)The neck and scroll is vertical and not twisted sideways
3) The nut is 130mm from the upper front edge
4)The depth of the mortise lets the lower end of the neck extend to the inner edge of the purfling groove or a little past it.
5) the height of the fingerboard over the upper edge of the front is 6 - 6,5mm.
6)The projection of the fingerboard at the bridge line is 27 mm
7) The heel of the neck meets the back button tightly all around and is sufficient for the back button height of 13 mm.

That sounds easy. Just dont forget that all this has to be a very tight fit because its going to be glued with Hot hide glue.
So I sharpened the chisel and started sawing and cutting and I´m pretty sure its all correct. This can of course be done with jigs and routers, but there´s something about sawing and chiseling within tent of a milimeter early in the morning, so thats what I did. Just like the old masters.
