In this picture I am installing the black mop dots on the side of the neck.

One more time I go over the whole guitar leveling out the surface and looking for anything that need attention..  

(231) 23-Jan-2010
In this picture I am using a filling compound to fill in all of the pours in the walnut.  I use a platten to force the compound into the pores and then I try to scape off the excess with out pulling the compound out of the pores.

(232) 23-Jan-2010
After the filler has set up I go over the guitar again with sandpaper to remove the excess filler and to look for anything else that needs attention.  I use a very bright light and high diopter pair of glasses so I can get a good look at the surface.

These are the tool I will use to install the headstock rose.

Finally into the paint booth.

(237) 23-Jan-2010
I am always happy with a spray gun in my hand.  In this process I spray on several coats of lacquer, sand it down level and then repeat the process until I am happy with the results.  The trick is to get enough lacquer on to protect the guitar's surface, provide enough material to accommodate the buffing process, and provide a bit of margin so future scratches can be buffed out, with out leaving any excess.  I.e., I want the finish thin, but not too thin.

While the lacquer is curing I turn my attention to building the bridge.  I use this tool to rout the channel for the saddle.  

(239) 23-Jan-2010
This fixture lets me slide the router along a well defined path while controlling the depth of the cut.

A picture of the finished channel.  This channel will hold the saddle quite snuggly.

Now that I have the bridge blank defined I am adding some binding and purfling.

(242) 23-Jan-2010
A look at the bridge blank with the binding installed.

(243) 23-Jan-2010
The next operation matches the bottom of the bridge to the top of the guitar.  Remember the top is in the shape of a dome.  I place a sheet of sandpaper on the top and then run the bridge blank across it until the two surface match allowing a good bond to be made when the bridge is glued on to the top.

(244) 23-Jan-2010
Here I am shaping the bridge using a belt sander.

(245) 23-Jan-2010
And finally the bridge gets the holes for the bridge pins.
