that requires the use of a precision outside mold. Unfortunately, construction of such a
fixture requires a large band saw and or the use of a large router and templates. The
Spartan Series© mold kits fills a void by providing an option to purchasing an expensive
ready to use mold or the necessity of upgrading ones shop with costly equipment. The
concept for these professional style molds is based on CNC technology. By using
computer controlled routers the mold sides can be accurately cut to shape, in addition
precision location holes are drilled that allow the sides to be stacked and pinned in
exact relationship to each other. The mold is made of FOUR layers of MDF totalling 3".
The sides are cut the preferred in and out contour design to allow the use of clamps on
the sides of the mold. The two mold halves are fastened with spanners so that the
guitar end blocks can be clamped and glued with out obstruction while the sides are in
the mold. The "D", Jumbo and 00014 profiles have been CMM quality checked and are
the exact profile of molds purchased from the C.F. Martin factory’s “Guitar maker’s
Connection”. The 00012 is based off the popular blue print sold by many suppliers. The
quality materials and a few minutes of assembly will yield a fixture that will last for many
years.

amount of glue into the pinholes; line up the layers than insert the pins. Seat the
pins all the way with a mallet. Clean up the glue pushed through by the pins.
Clamp the side assembly to a sturdy table/bench as illustrated in the picture. This
clamping method assures that the assembly will be flat when the adhesive dries
spanners and ten screws at each end. Clamp the sides at the waist making certain
that they are in perfect alignment. Clamp the spanner in place at the centerline.
Pre-drill all ten holes. Check alignment as the spanner is secured with the screws.
Repeat above procedure for the other end

the mold smooth – this will allow the sides of
the guitar to be removed more easily.
