« Part 2: Some Jigs and a Neck Glue-Up Part 3 of A Tale of Two Guitars series Part 4: Truss Rod Channel and Tenon »

Started off by trimming up the neck blank and planning it square.

**Just a note here: I couldn’t find anywhere that definitively instructed on the width of the neck blank. At the guitar joint, the neck is 2-1/8” wide and at the nut it is 1-3/4”. But, since the headstock is made from the same blank, most are 3” wide due to the widest part of the headstock. So we went with a 3” wide blank (however, my headstock will taper the opposite way as normal, so I could have glued up a thinner blank).

Then cut the scarf joint 7” down from the end of the blank at 15° using a Veritas crosscut carcass saw (sorry, no pictures of this).

Turned the headstock portion upsidedown and clamped it up on top of the neck.

Then planed the two pieces flat and squared up.

I love maple and walnut laminated shavings…

Once the scarf joint was flat and square on both the headstock and neck, the headstock needed to be planed down to ½” thick (neck blank was a little over ¾”). Using some cauls, we clamped up the headstock to the neck.

We are doing all the work in my shop, so if I get ambitious, I will go down and work ahead a little which seems to help me figure out the techniques and apply them to my dad’s guitar. This was the case with the neck. Once the scarf joint was dry, I worked on the heel block. I began with measuring the nut width (3/16”) from the edge of the headstock. Then I measured down 14.08” from the nut line to mark where the neck will contact the body. Then another 1” down for the tenon. This left about 19” of neck blank to make the heel block. Cut 4 x’s 4” sections and 1 x’s 3” block. Alternating the blocks’ grain directions, I stet them up even with the end of the tenon mark and glued them up.

And here is the progress on my neck in my bench vise.

As always, thanks for reading!
