I used the video as my guide. What was confusing was that I had good contact all the way. Right down until about the last drop of 1/16". That's when things started going out of whack. At that point the chalk wasn't helping me figure out what was wrong as it was showing up consistently all the way down. Really weird because the last time I did it everything was the same as the time before yet, it fit like a glove this time round. I'm sure after a few I'll have it down to a science. :-)

I have experienced that exact same thing and can't figure why it goes loose in that last skoosh.

I think you may have something that is holding you off , be sure all corners are chamfered and the lower part of the tenon is taken off. If you have a male sharp corner it can bottom on the female corner and this can do all kinds of strange things.

Keep an eye on the corner of the joint where the fretboard comes on the top as long as that is tight you should be fine. If you shimmed it to see a slight gap then work is so you clamp it and the pressure closes that you will be fine. It won't spring once the glue sets
If the corner is the key, how much is it possible to force it down with a clamp? I don´t have the feel for how much I could to press it down. I´d like to have a tight corner before claping, but then I´d loose the tightness. Is a business card of space to much?

a business card is about right . You need to be sure you didn't round the top at that point. This is easy to check with a straight edge

I don´t have any finish on the neck yet, but here it´s easy to see. If I press this down, is it a risk that I crack the back above the tail block?

Use a leather pad and be sure you are on the neck block. That should be good to go

Haggis,

Is there any downward pressure on the neck in that picture, or is it just sitting loose?

Jim.
It´s tight at this point, but if I try to shave more material of the heel, i´d probably loose the tightness. In my first attempt of getting it down I lost the tightness. This gap is just under 1 business card and I still have a tight joint. I rebuilt the surface after my first try.

NOTE : Beware of the male/female areas of the joint. Often the male sharp corner may hold off the joint from seating . This can be where you for from ok to awful .

John. I believe you´re right about the dove tail. I managed to adjust the angels center/hight among the way. I´ll choose the dove tail on my next build as well, but I´ll pay more attention to the "scrub sanding" part of it to get the look better.
