| 1. Wood Collection |
| Wood suited to pianos
is collected from locations like Alaska and
Romania. |
|
| |
|
 |
| 2. Natural / Artificial
Drying |
Natural drying techniques
air dry the wood for anywhere between half
a year to two years and artificial techniques
that dry the wood in a closed environment
under computer control. The moisture content
of the wood decreases from 70~80% down to
around 8% through these methods.

 |
| 3. Making Soundboards |
| Well-dried square
wood pieces are processed into thin boards.
These thin boards are joined together with
aligned tree buds and rings to make a soundboard.
Finished soundboards are stored in a temperature
and humidity controlled environment. |
|
| |
|
 |
| 4. Making Frames |
| A vacuum casting process
is used to create an iron frame of great strength.
Each iron frame plate is tempered, seasoned
for six months, then stress tested before
installation. |
|

|
 |
| 5. Making Keyboards |
| White, straight grained
spruce boards are put together in piano keyboard
sizes, then divided and cut into 88 keys. |
|
| |
|
 |
| 6. Making Hammers |
| Hammers are made by
winding wool pelt onto a wooden core. |
|
| |
|
 |
| 7. Making Action |
| The action is a system
of complex and delicate parts that convey
key movements to the hammer. 0.05mm processing
accuracy is required in assembly of the action,
and approximately 6,000 pieces form a piano's
action. |
