After registering on that forum I've just seen Waddy's tutorial. That's virtually identical to the method I use, even his method of clamping the head. Some makers will use a jig that ensures that the head piece remains at the correct angle when it comes to the glue-up. I've never found it necessary and just use the same set up as Waddy's.
There is an excellent article by Geza Burghardt in the fall 2000 (#63) issue of American Luthierie (GAL) on making the "V" joint.
This article shows how to make the through "V" joint a' la' Romanillos.
The blind "V" as used by Hauser is well illustrated in Richard Brune's plan of the 1937 guitar but I'm not aware of any instructions out there on making it.
The main difference in the final form of these is that the the peghead veneer joining surface stands proud of the fretboard joining surface in the Hauser where in the through joint they intersect at the nut area.
The modified bridle joint was used by Martin and others for 3 piece necks all during the 19th century and is actually a bit more complex than the other two. All are quite elegant though.
