Now I start working on the binding. Here I am using the drum sander to dimension the individual cocobolo strips.

( 195 ) 14-Nov-2014

I will using the bending machine to shape them. Here they are going into the heating blanket.

( 196 ) 14-Nov-2014

 

( 197 ) 14-Nov-2014

The bending machine.

( 198 ) 14-Nov-2014

 

( 199 ) 14-Nov-2014

When I am done the strips have the shape of the guitar body.

( 200 ) 14-Nov-2014

Before I install the binding I sand the top and back around the rim.

( 201 ) 14-Nov-2014

And then I sand the sides smooth.

( 202 ) 14-Nov-2014

I use my bindalator to route the channels for the binding.

( 203 ) 14-Nov-2014

This tool holds the router vertical as I work my way around the rim.

( 204 ) 14-Nov-2014

The back channel

( 205 ) 14-Nov-2014

The top gets and extra channel for the purfling.

( 206 ) 14-Nov-2014

The top channels.

( 207 ) 14-Nov-2014

I use a few shims to center the heel in its channel, and then I mark the side for the heel binding.

( 208 ) 14-Nov-2014

I use a small saw to cut on the marked line.

( 209 ) 14-Nov-2014

And then a chisel to create the channel.

( 210 ) 14-Nov-2014

 

( 211 ) 14-Nov-2014

Now with the neck installed in the body I trim the binding until they just fit into the channel.

( 212 ) 14-Nov-2014

After gluing the binding in place I cut a little bevel into the pin striping

( 213 ) 14-Nov-2014

And then I install the rest of the pin striping.

( 214 ) 14-Nov-2014

 

( 215 ) 14-Nov-2014

Next I install the cocobolo binding.

( 216 ) 14-Nov-2014

It looks a bit messy.

( 217 ) 14-Nov-2014

 

( 218 ) 14-Nov-2014

But have no fear, it cleans up nicely.

( 219 ) 14-Nov-2014

 

( 220 ) 14-Nov-2014

Now with the binding installed I can return to the neck. I drill two holes where the fulcrum set screws in the heel channel contact the neck.

( 221 ) 14-Nov-2014

And then I install two short brass plugs.

( 222 ) 14-Nov-2014

I sand these flush with the heel.

( 223 ) 14-Nov-2014

Here is one of the fulcrum set screws... the end is shaped into a point.

( 224 ) 14-Nov-2014

Next I fine tune the hidy-wing channel.

( 225 ) 14-Nov-2014

When I install the neck and tighten it down, the set screws press into the brass plugs making firm contact and leaving a small indentation..

( 226 ) 14-Nov-2014

With the neck in place I use this special sanding tool the level the end of the heel for the heel cap.

( 227 ) 14-Nov-2014

To make the heel cap I first install the pin striping.

( 228 ) 14-Nov-2014

And then I glue the end cap on to the heel.

( 229 ) 14-Nov-2014

Next I use my CNC router to route the channel for the head stock rose inlay.

( 230 ) 14-Nov-2014

A few hand tools ...

( 231 ) 14-Nov-2014

and I install the gold wire into the channel.

( 232 ) 14-Nov-2014

Here is the Portland Guitar Rose.

( 233 ) 14-Nov-2014

Now I use a small file and some polishing pads to dress the ends of the fret wires.

( 234 ) 14-Nov-2014

The top of the guitar has a 20 foot radius, so the bottom of the bridge needs to match it.

( 235 ) 14-Nov-2014

I use a shaped sanding block to sand the bottom of the bridge blank.

( 236 ) 14-Nov-2014

And then I glue the pin striping to the bottom of the blank.

( 237 ) 14-Nov-2014

And then the wings are formed with the oscillating sander.

( 238 ) 14-Nov-2014

Ready for the saddle plate.
