I use my CNC Router and a very small mill end tool to route the channel for the head stock inlay.

I use square silver wire to create the inlay.
( 295 ) 11-Jun-2015
The wire stands a bit proud of the surface.
( 296 ) 11-Jun-2015
I sand every thing flush and smooth.

The Portland Guitar Rose.
( 298 ) 11-Jun-2015
I use a PVC dowel to create the side dots.

Surface prep is critical to getting a good finish. I fill the pores and level the surface with several applications of epoxy and leveling steps..
( 301 ) 11-Jun-2015
My present spray set up.
( 302 ) 11-Jun-2015
After the nitrocellulose has cured, I level the surface again using progressively finer sanding and polishing cloths.
( 303 ) 11-Jun-2015
Eventually I get a high shine I am satisfied with... it is never perfect, but I am getting closer.

The CNC router is used to rough out the bridge.
( 305 ) 11-Jun-2015
I lay a piece of sandpaper on the top of the guitar and sand the bottom of the bridge until it matches the top.
( 306 ) 11-Jun-2015
The oscillating sander creates the wings.
( 307 ) 11-Jun-2015
And after a bit more work that I forgot to take pictures of I drop in the saddle plate.
( 308 ) 11-Jun-2015
To glue the bridge on I first lay it out on the top of the guitar.
( 309 ) 11-Jun-2015
Then I score the perimeter.
( 310 ) 11-Jun-2015
Then I carefully remove the finish where the bridge will be glued to the top.
( 311 ) 11-Jun-2015
A couple of clamps and a special tool presses the bridge in place.
( 312 ) 11-Jun-2015
( 313 ) 11-Jun-2015
Now I drill the holes for the bridge pins.
( 314 ) 11-Jun-2015
I decided to turn an end pin from an ebony dowel.
( 315 ) 11-Jun-2015
And then after making the saddles and a bit more work that escaped my camera, the guitar gets strung up. Check the Photos out.
