The
soundboard and the back are ready to be mated with the sides.
The back was built on a concave board with a 15’ radius. The
back face of the sides have been sanded with that same concave
board so that the back and sides will mate properly. The sides
and side kerfing was cut out so that the back braces will fit
in the grooves. Sorry I forgot to take a picture of that. The
back was then glued to the sides. |
 |
The
back overhang was trimmed with a flush cut router bit and the
sides and back turned over in the mold. You can see the cut
outs for the back braces in the sides in the picture below.
You can also see some temporary bracing installed to keep the
guitar shape until the top can be glued on. The top of the sides
have been sanded with the concave dish used to brace the soundboard;
this one to a shallower radius of 30’. |
 |
I
have cut out grooves in the kerfing and top sides to accept
the soundboard braces (again I forgot to get photos). The soundboard
is glued to the sides:
|
 |
The
soundboard will now be flush trimmed to the sides. With the
mating of the sides, back and soundboard; the sound box is one
piece.
|
 |
A
lot of little jobs need to be done to make the sound box look
better, resist damage from impact to the edges and minimize
the effects of humidity changes. Some of these are documented
in the pictures below. |
 |
Cutting
the binding channels - The bindings & purfling that will
occupy these channels will be decorative, strengthening &
humidty protective. |
 |
Installing
the back strip - Decorative and strengthening
|
 |
Installing
the end graft - Decorative and strengthening
|
 |
|
In
the next post (POST 5) I will match the purfling on the end
graft and back strip to the purfling on the bindings, install
the bindings and rough sand the sound box. Thanks for watching
and please email me with any questions or comments you might
have, Thanks -mdg
