|1. Storage and treatment
of the wood materials|
For wood instrument, dryness is very
important, as well as the bow. We have owned a large storage
warehouse to store the materials for 10 years¡¯ consumption. After
purchasing the materials, the log is planed and placed in a
high-temperature room for storing about 1 year to evaporate water
the oil grease, and placed in a ventilated warehouse for 5 years for
manufacturing. For Brazilwood, it shall be stored longer.
2. Preparation of bow frog
bow frog is the main fitting which is hardest to prepare. The Burma
ebony quality is fine, the color is pure and it is a good material
for preparing the bow frog. The dried ebony is processed to a
primary form of the bow frog, after complicated working procedures,
including embedding, grinding, slotting, carving, polishing and
etc., and the preparation is completed.
Forming of arc of the bow
Arc of the bow is formed after
heating. First, we heat up the mold, and place blank of the arc rod
into the mold, take it out 10 minutes later and the basic arc is
formed. The more precise arc is formed in processing with fire for
4. Preparation of the bow
Key factors of the bow head is precise size and nice
modeling. A good model makes us nice. Head of the blank bow head is
rectangular. First, we process it into the primary form of the bow
head, and ebony piece and cattle bone piece are stuck on the bow.
After the glue is dry, a perfect bow head is grinded with a file and
sharpen knife. At last, an echelon hole is formed at the surface of
assembling the bow wool. (There are too many modeling, we also
employ two types, one is PECCATE from France and the other is
5. Assembling of the bow
Key of assembling the bow frog is to make
stabilization between the bow frog and arc rod and the adjustment
screw can be adjusted flexibly. We open a slot on the end of the
blank arc rod, which shall be on the same plane with the arc head; a
deeper hole is punched, which is punched from the end of the arc
6. Assembly of the bow
After assembling the bow frog, we start to assemble
the bow wool. Key points of bow wool are flatness and firmness.
Before assembling, the bow wool shall be inspected and bundled, and
one end of the bow wool is assembled into the bow wool slot of the
bow frog and sealed with a wooden sleeper. After combing with a
comb, the other end is assembled into the bow wool slot of the bow
frog and sealed with a wood sleeper.
Preparation of the bow rod
Preparation of the arc rod
affects use of the bow. We make the bow rod into an octagonal shape.
During manufacturing, continuous baking is required to make its
straightness and arc. Besides, we measure its balance point and
control weight of the bow to reach the optimum status. After the
octagonal shape is completed, some of them need to be round rod, so
we make it a hexadecanoic shape based on the octagonal shape to make
it round. The whole process is the spirit project of the arc
Painting is to wear nice clothes for each bow.
Before painting, three grindings are required. The first step is to
grind with a piece of coarse grinding paper, the second step is to
grind with a piece of medium grinding paper and the third step is to
grind with a piece of fine grinding paper. After the bow rod is
completed, place it into a sealed box with chemical mist to make it
radiated from ultraviolet and shell-lac paint shall apply. After
painting, it is polished with a piece of soft grinding paper. The
whole process is complicated, but more important is that clear wood
grain can be seen on the bow rod.
After painting, metallic wire is wound on the
bow rod and animal skins (such as sheep skin, lizard skin and etc.)
are applied on it. After polishing parts of the bow and checking it,
a practical and nice bow is formed.
