Here are the pictures I promised:
First this is I how cut my scarf joints: I simply trace it out and chop it up with a standard saw (albeit one of good quality). I draw two lines 5mm apart, to make it easier to track my cut.

After that I stack the two pieces and shoot the joint with my handplane.

It would be easier to stack them the other way around, but this way I can see the line where the nut will be and make sure I keep that perpendicular to the neck centerline.
You can also see that my saw had a bent tooth! I've since fixed that. Those scars did give me a little more work but it still was a quick job shooting that joint.
The glueup is done with Titebond original. I start with a test fit and then drill for centering nails. These keep the pieces from sliding out of alignment when clamping. The glue makes it a very slippery business without this precaution.

When the glue is dry I clean up the face with the handplane and glue my veneer: a bookmatched curly maple face (1.5mm thick, from an offcut of the top) and a contrasting dyed maple veneer (same as used in the body).

The headstock is brought down to the desired thickness (15mm including the veneers) using the router on rails again. I then carve the headstock side of the volute, with a gouge followed with a sanding drum.

You can see the neck is already carved in this picture, A "beauty mark" appeared on the treble side of the neck, wood is a natural product!

The scarf joint is quite discreet so Flo and I decided to keep the lovely neck wood visible on the back of the headstock (on which I would usually glue a dark veneer).

After routing for the trussrod with the parallel guide, the fingerboard is glued in place. It then serves as a template to route out the neck with a flush-trim bit (after the excess wood is sawed off). It's a spiral bit and it doesn't produce any tear-out!

The neck is carved. The first step is done with the router again. I used a U-shaped jig in which I place the neck on blocks that allow me to route the neck to its tapered thickness.
Then in comes the Dragon rasp! I bought it for this project, and it's worth the price. It's really fast. I then followed with a spokeshave (bought on Ebay, following the wise advice provided on this very forum!), it's a very nice tool. After some careful sharpening it takes nice shavings of curly maple without any tear-out.

The transition part is carved using a gouge, it will be refined after the neck is glued in.
For carving, I followed some cardboard templates I made off Flo's Fodera's neck. The profile is the same except that there's some wood in the non-cutaway portion!! The carving still allows a normal playing position almost up to the end of the neck. Of course we will double-check the playability before finishing...
