There is plenty of wood in this 3" x 30" neck blank to cut and laminate for this project. So, work scant and leave yourself room to make the sections square and true after cuttng.
Since about October 20th a laminated guitar neck has been built in the shop and this page was assembled. If there are any questions, Woody can be reached at: Woody@woodystrings.com
Below are photo cross sections of the sapele neck stock used to build the neck described here. The photos show how the wood has cupped as it has dried out in the shop. This neck material was purchased in 2017 from LMI. Understand that no matter where one buys tone wood, it is a good practice to assume that the stock needs to be control-dried at least through a couple of winters. One should square and true up the neck-stock surfaces before beginning to build the guitar neck described here.
When cutting to your dimensions it's a good idea to leave everything a few millimeters large to ensure that you can square and true all of your joints and still come out with the fretboard dimensions and location that you planned.
Next, the glued-up neck needs the converging laminate lines drawn on it. Masking tape makes the lines easier to see. Woody cuts along these laminate lines with a 12" bandsaw and a 1/2", 18 tpi, bi-metal blade. Cut slowly and keep the kerf as straight and true as you can. This glue joint will be ~22" long with a 15 degree bend at one end. It must be square and true for the full length.
The neck is now ready to be sliced into three sections which will be laminated with flat maple stock (~3mm thick).
Glue, Clamps... and a Workboard.
Laid up, pinned, glued and clamped (24 hrs).
When finished, it should look something like this.
Cutting and gluing the maple laminate head at this point will ensure that all five pieces will have the same pattern and neck angle.

Now we have built the laminated neck. Next month Woody will have some photos and a discussion on carving the neck and inlaying the truss rod.
Hope to see you back here next month.
Shown below are photos of the standard process of cutting the neck stock and gluing it up with a scarf-jointed headstock and a built-up heel. This is how Woody does it. There are a few other ways but Woody has his reasons. Suffice it to say that wood laminations are more stable and stronger than solid wood.

Pictured above in the center is a not-so-great photo of a finished guitar with a converging-line laminated neck. The maple white lines bordering the center piece of the back are visually extended up the neck to the head. The intent of building a mahogany/maple laminated neck this way is to be structurally sound and visually appealing.
The photos on the left and right (above) show only a bit more detail of a Woody guitar using converging-line laminates to reinforce the neck against shrinking and bending.
