Out of the three books I've been using as reference, only the Waring book mentions doing the neck as follows: shape the back of the neck first, let it sit for a few days, then check for flatness of the front (joint as necessary), then route the truss rod channel. The other two books don't make this distinction. Now, he's making a single piece flatsawn maple neck (I believe). I, on the other hand, and making a 5 piece laminate of wenge/purpleheart, and it is almost down to the correct thickness. Should I shape the back and wait for it to correct (due to release of tension in the wood as stated in the book)? I was thinking about routing the TR channel and the graphite strip channels first, installing, tapering the fingerboard, gluing it down, tapering the neck, and then shaping. Am I asking for trouble?
