Here I'm using a spokeshave to remove wood between the two roughed out areas. I don't have much experience using a spokeshave and this wasn't going well. I seem to get a lot of chatter as I pull.

I seem to have better luck using the ole Stanley hand plane.

After roughing out the shape, I think I've found my shaping tool of choice........... the Ridgid belt sander. The sander is short enough to work between the first and 12th frets. Here I'm just rocking the neck back and forth letting the sander do the work. This works great because you don't have the neck clamped to a table. You can instantly check the feel of it.
