| ADMIST THE LATTICES
The latticework designs are a bracing system to
enable the soundboard to vibrate freely while giving
support and structure to the soundplate.As the bracings
intersect at angles and are meticulously notched one
bar over another the soundboard is quite taut and
well braced. The internal latticework enables the
soundboard to be constructed thinner yet structurally
At Sergeis the actual lattice patterns are
available for use that the De Jonge Luthiers have
developed and yet Sergei does not hesitate to let
you modify or redesign your own lattice patterns. Starting
off thicknesses for a classical run between 2.2 to
2.3 mm. Bar bracings run a range from 7mm x 15mm for
main bracework to 3mm x 6.5 to 3mm x 4.5 for secondary
bracings.For the backboard...traditional horizontal
transverse bars are used ..at any where from 12 to
15mm high and 7 to 9.5 mm thick.Bars are tapered to
about 2mm at ends which are notched into the tentalones
and ribs when fitted to the sides. The pattern I used
in Oshawa was a modified splayed fan lattice..the
pictures will show general layout and the spacings
start from about 2' courses to 1 and ½ inches.
Aside from the soundboard...the guitar construction
was typical of the Dovetail body to neck assembly of flattop construction.
Starting from selected woods ,provided by Sergei;
we used East Indian Rosewood for bookmatched backs and end matched sides.Sitka
spruce was chosen for the soundboards ; while Honduran
Mahogony or Spanish Cedar was used for the necks.Headstock
plates were made from matching East Indian pieces
and the Rosette materials and design was left to our
own imagination.I used a sectional Cocobolo ring outlined
in green bindings to form a segmented Cocobolo Rosette.
