I like to use slightly worn 150 grit 3M sand paper to sand all sharp corners on the headstock and heel of the neck. Then the back of the neck and top face of the headstock. Use your hand so you can get a feel for the surface of the wood. Try using a sanding sponge block on the edges if over 150 grit. When the neck feels and looks scratch free, the neck is ready for finishing.
Using a template with the center lines for the tuner key locations, pencil the center point of the holes onto the headstock. Next, set up the drill press with the recommended drill bit for the tuners recommend size. Make sure to use a brad point drill bit to get the cleanest cut at the top face and back of the hole. Next, we need to have a backing plate of wood to put behind the headstock so the drill bit does not tear out the grain on the back side of the headstock. After all holes are drilled, block sand top and back with 150 grit 3M sanding paper.

For the advanced technique in lowering the headstock to the desired thickness, check out the ebook Building Necks at jcsmi.com
Using the band saw in conjunction with the fence, set the thickness just over the headstock thickness. Advance the headstock with the back of the headstock sliding flush to the fence. Stop the cut with room to intersect the cut with another angular cut. Make sure to leave enough room to spindle sand a transition to the new face of the headstock.
Block sand top face of headstock with respective sandpaper starting with 60 grit and ending up with 150 grit.
The next step is adding the radius to the fretboard. We need to use the drum sander to bring the neck down to the desired thickness. I use 1 inch from the back of the neck to the top of the fretboard. Now we will need plenty of chalk, in a variety of color. The reason for this is my use of multiple colors of fretboard also neck materials. Chalk is applied after every pass on in the sanding and machining process so you can never have enough. a radius gauge and a belt sander. Start by carefully removing wood from both sides of the fretboard and check the surface the radius gauge often. Apply more chalk on the fretboard as the belt sender removes the wood. Rock the neck back and forth over the belt sander trying to keep from removing the wood at the centerline. Using the radius block and 60 grit paper, bring the radius to match the radius template. When matching the radius, use a sanding pad approximately 3/8ths thick in your palm and rub 80 grit up and down the fretboard till smooth.
This is one of the most critical parts of the neck build. The neck has to feel right in your hand. Take the opportunity to check for the correct fit in your hand often in the shaping process. In doing this, your neck will give you many years of enjoyment.
The first step in the process is to belt sand the sides of the neck. The profile work we did in Stage 11) will leave the sides close but not as flat and square as we need them to be. Once they are flat and square, use the transition templates to trace the line on the back of heel and back of headstock. The lines represent the shape of the flats that have to be preserved when shaping the back of the neck. For the manual removal of stock, use an aggressive rasp file and start by long angular strokes. Using a contour gauge, press down on the back of the neck at the first fret and compare to the curve you are trying to match on the reference paper. Reset the contour gauge and take the second reading at the middle of the neck and compare to the curve you are trying to match on the reference paper. Then reset the contour gage and take a third reading at the 12th fret and compare to the curve you are trying to match on the reference paper. When you have the back of the neck close to the shape you want, use the palm sander with 40 grit sanding paper. Using long strokes back and fourth, remove the rasp filing marks and get as close to the feel you are looking for on the backside of the neck. Check out the ebook for details on how to use power tools to aid in your stock removal process. For the transitions, use the 4 in one file at the heel. For the headstock, use the round file. Shape till comfortable and flowing in appearance. It pays to have a reference neck to look at. Finish using sand paper wrapped around soft sanding cylinders.
