The instrument pictured here was commissioned
by John Oster of Davis, California, and
completed in March of 2008. The back and
sides are made of Ziricote, a dense tropical
hardwood that grows in southern Mexico and
Central America. The sides are laminated
with Alaskan yellow cedar, and the top is
very well aged western red cedar. The scale
length is 655mm, which I think is an optimum
length for the larger of the two body sizes
I build. This guitar has acoustic sound
ports and is French polished.
Building a guitar involves hundreds
of steps, so what I am presenting here must
necessarily be condensed. Still it is my
hope that seeing these photos will give
you an overview of what it takes to go from
raw wood, bits of metal and bone, and shellac
flakes and alcohol, to the finished product.

|
| The
ziricote sides have been bent and laminated
to another set of sides made of Alaskan
yellow cedar. |
Four-piece
back has been reinforced and braced, ready
for shaping and scalloping of the ends to
fit into the lining mortices. |
|
|
|
| After
the bottom and neck blocks are glued in,
the back is glued to the side assembly.
The linings are made of cherry. |
Here
the body is ready to have the top glued
on, after shaping the top edge of the sides
and gluing the label in. |
|
|
|
| The
first step in making the MOP rosette. I
remove the bulk of ebony with one router
bit, then define the lines with a smaller
one. |
Here
the pearl has been inlaid. You can see the
lines delineating the eventual inside and
outside radii of the ebony ring. |
 |
 |
| The
rosette has been inlaid and scraped flush
with the top. Now the top can be turned
over and thicknessed and braced. |
The
top is being braced in the go-deck. Here
the second round of fan braces are being
clamped. |
 |
 |
| This
is the completed braced top, ready to glue
to the body. The treble bar is let into
the lower transverse brace. |
My
main workbench on a typical day. The top
is almost done, needing the large transverse
braces to be shaped and scalloped. |
 |
 |
| This
is the finished body, ready for the back
and sides to be scraped and the binding
ledges routed. |
The
first piece of back binding/purfling is
being tied on. When I'm feeling particularly
ambitions I will tie both pieces at once. |
 |
 |
|
This is my setup for tying on the bindings.
This guitar does not have a back strip,
so there are four less miters to cut. |
Here
the string slots have been routed, and the
string ramps chiseled. A bit more chiseling
and sanding and the head is done. |
 |
 |
| The
neck/heel assembly is shaped in this jig
to match the curvature of the body. You
can see the spline slot in the heel. |
The
guitar has been fretted and the neck shaped,
final sanded, and then stained to darken
the maple bindings. |
 |
 |
| The
stained ziricote headstock. There is a thin
green veneer that you can't see under the
ziricote, that is in the bindings and rosette. |
The
back of the head showing the transition
from the neck to the head. The inside edges
have a small chamfer. |
 |
 |
| This
shot shows the ziricote heel cap and the
ports. The ports do not need a reinforcing
veneer because of the laminated sides. |

rosette, acoustic sound ports, and warm
color of the maple bindings. |

 |
| This
shot shows the mother-of-pearl rosette,
the label, the stamp that I use on the foot,
and the twentieth fret. |
