Unfortunately I got so wrapped up in carving the neck (my favorite part) that I forgot to take pictures of the process. Nonetheless we can see the results.

Here is a picture of the volute a little farther along.

I have set up the milling machine to drill the holes for the neck adjustment hardware.

( 258 ) 14-Apr-2015

I drill all the way through the heel. This hole will give us access to the adjustment bolt and it will house the strap pin.

( 259 ) 14-Apr-2015

The hardware has a compression ring to prevent it from rattling around. I apply a bit of pressure while the glue sets up.

( 260 ) 14-Apr-2015

And then I drill two holes though the retaining flange and install dowels that will hold the flange firmly in place.

Before carving the neck I mask off all of the areas I don't want to remove any wood from. I use a variety of power and hand tools to slowly bring the neck to its final shape.

( 263 ) 14-Apr-2015

Here I am drilling holes for the tuning machines.

( 264 ) 14-Apr-2015

I installed burled maple rings to frame the tuning machines.

Now I am ready to install the binding. First I route the channel for the binding with my "Universal Bindalator."

( 268 ) 14-Apr-2015

This tool allows me to route the channels while holding the router parallel to the sides.

( 271 ) 14-Apr-2015

Before gluing the bindings in place I prepare the edge of the spruce top with some nitrocellulose. This prevents the glue from wicking into the grain and discoloring it.

( 272 ) 14-Apr-2015

The channel around the heel gets a bit of special attention.

( 273 ) 14-Apr-2015

 

( 274 ) 14-Apr-2015

Starting to glue the pin striping in place.

( 275 ) 14-Apr-2015

I have mounted the neck in the heel channel and centered it.

( 276 ) 14-Apr-2015

Now I can fit the binding around the neck and get a good fit.

( 277 ) 14-Apr-2015

 

( 278 ) 14-Apr-2015

Tape and glue to install the binding.

( 279 ) 14-Apr-2015

 

( 280 ) 14-Apr-2015

The binding is installed proud of the top surface and gets sanded down flush with the top.

( 281 ) 14-Apr-2015

The binding was installed shy of the side surface and the side gets sanded flush with the binding.

( 282 ) 14-Apr-2015

The following are a few pictures of the results.
