                                After the braces are rough-shaped, Chris
                                proceeds to contour the braces by hand using a
                                finger plane.  | 
                                 | 
                                 
                                  The area where the main "X"
                                  braces meet is sculpted with a chisel.  | 
                                 
                                 
                                   
                                  
                                      | 
                                       | 
                                       
                                        Once the braces are scalloped to
                                        their final shape, Chris smoothes and
                                        fine-tunes the braces using sandpaper.  | 
                                       
                                     
                                       
                                  
                                     
                                        Continuing with the sandpaper, Chris
                                        tap-tunes the top, fine-tuning the
                                        locations of the "live" areas
                                        of the top for maximum response, and carefully shaping and
                                        smoothing the braces until the desired
                                        resonant qualities are achieved. A
                                        practiced ear as well as skilled hands
                                        are required here, as is the knowledge
                                        of how the top will interact with the
                                        specific set of wood chosen for the back
                                        and sides of the guitar.  | 
                                       | 
                                       
                                        The body has been assembled, and the
                                        neck has been rough-shaped. Peghead
                                        veneer has been installed, the channel
                                        for the adjustable truss rod has been
                                        cut, and the fretboard has been profiled
                                        and slotted for frets.  | 
                                       
                                     
                                       
                                      
                                          | 
                                         | 
                                         
                                          The body has been prepped and routed
                                        for binding. The neck is nearly
                                        complete, with adjustable truss rod and
                                        fretboard installed. Peghead inlay is
                                        complete, inner purfling of fretboard
                                        has been glued in place, and frets have
                                        been installed in the fretboard. Outer
                                        binding of the fretboard will be glued
                                        on and finished to the ends of the frets
                                        at a later stage.  | 
                                         
                                       
                                         
                                        
                                           
                                            Body now has "Zig-Zag" back
                                      strip glued in place. Pencil marks on
                                      upper bout are guide marks used for
                                      routing the binding ledges.  | 
                                             | 
                                             
                                              Detail shows "Zig-Zag" back
                                        strip and inlaid purfling at end pin
                                        area. Wooden insert at end pin appears
                                        to be a different color due to the
                                        lighting, but is actually an identical
                                        piece of Cocobolo with the grain turned
                                        at 90 degrees. Routed ledges for outer
                                        binding and inner purfling are apparent.  | 
                                             
                                           
                                             
                                            
                                               
                                                Grained Ivoroid binding is applied with
                                      quick-setting epoxy. Binding is
                                      hand-fabricated by Chris from sheet stock,
                                      so many binding choices are available.  | 
                                                 | 
                                                 
                                                  Binding continues around the top.
                                        Inner purfling and outer binding are
                                        applied at the same time.  | 
                                                 
                                               
                                                 
                                                
                                                   
                                                    Once the epoxy for the
                                                    binding has sufficiently
                                                    set, Chris levels the
                                                    binding to the top with a
                                                    file. 
                                                   | 
                                                   | 
                                                   
                                                    Next, the binding is
                                                    scraped from the side with a
                                                    blade, removing any excess
                                                    glue and truing the binding
                                                    surface with the sides.  |
