Process taken in our shop, October-December 2009: |

2 -
We were impressed with the beautifully painted rim. This explained,
in part, why the owner was really "attached" to the piano and wanted
us to restore it. |

3 -
We removed the bass strings for delivery to the string-maker for
duplication. |
|

4
We loosened the
treble strings and measured sizes for making our stringing gauge
which will be used during restringing to ensure replacements are the
proper size. |

5 -

6 -
We removed the dampers and placed them in temporary storage.. |
|

7
After removing
the treble strings, we removed the pins with a special bit in our
1/2-inch power drill. |

8 -
After removing all plate bolts and placing them in storage in the
correct arrangement for easy replacement, we lifted the plate out of
the piano using our ceiling-mounted winch. |

9 -
We removed the "back action" to which the dampers are attached, for
reconditioning. This action will be re-installed after restringing. |
|

10
We removed all
surface dust from the board and elsewhere. |

11 -
We covered the piano with blankets and installed a heater below the
board in order to dry it overnight at low heat. |

12 -
After drying, the board showed several thin cracks which need to be
shimmed. This will make the soundboard to a one-piece vibrating
diaphragm, essential for good piano tone. |
|

13
After all
grooves had been shaped with our shimming tool, we cut V-shaped
strips of spruce wood and glued them in place. After this dries, we
will clean off the excess wood and refinish the soundboard and
bridges. |

14
With a
chisel we removed the exposed sections of woodshim, and with paint
scrapers we removed the original varnish from the surfaces of the
bridges and the soundboard. Next we will sand the surfaces and apply
sealer and semi-gloss spar urethane. |

15
After
close examination of how the original pinblock was installed, we
decided to remove it by cutting it from the frame and then breaking
the glue-joints and dowels that held it in place. Then we sanded the
surfaces on which the replacement pinblock will be installed. We
will next use the old pinblock as a pattern for making its
replacement. |
|

16
We cleaned and
polished the agraffes and hitch pins, and we scrubbed the plate with
soap. |

17
With the old
pinblock screwed in place, we lifted the plate into the piano,
placing the plate and pinblock in the correct position. With these
parts in the proper position, we can prepare a sketch and record
precise dimensions for the replacement pinblock. |

18 - We sketched
the pinblock position on a piece of butcher paper and recorded all
measurements we would need for returning the plate and new pinblock
to their proper location. |
|

19
We began the work
of reconditioning the action by replacing all the whippens with new
ones. |

20
We drew the line
of the front edge of the pinblock on new pinblock material and made
the first "rough cut" using our jig saw. |

21
We made a
milar plastic pattern of the pinblock which will help us improve the
fit. |
|

22
We
corrected the cut of the pattern by placing it in the plate. We will
use this template to improve the line of the new pinblock. |

23
We applied
a layer of blue chalk to the plate surface and checked the accuracy
of the cut by putting the new pinblock in place. |

24
We sanded
the chalked areas of the pinblock, placed the pinblock in place,
then sanded again, etc., until the chalk marks showed along the full
length of the front of the pinblock. |
|

25
We clamped the
pinblock into position for the final check. |

26
When the
chalk marks showed along the length of the pinblock, we were sure
that the pinblock would accept the tension of the strings. |

27
We cleaned
and polished the plate screws. |
|

28
With the
pinblock clamped to the plate, we drilled holes for the screws and
installed the screws. |

29
We drilled
short "starter holes" to mark the exact location of each tuning pin. |

30
We marked
each tuning pin hole with black marker. |
|

31
We used
previously made pattern blocks to mark the cut line where the
pinblock will fit into the rim of the piano. |

32
We used
our large wide-arm drill press to drill the tuning pin holes, at an
angle of six degrees.. |

33
We
installed the finished pinblock in the keybed area with black felt
at the rear edge to prevent squeaking or rattling during
playing. |
|

34
We
inserted carpenter's glue into the cracks in the piano rim and
clamped the repair area overnight. |

35
We applied
sealer to the soundboard and bridges. |

36
We applied
a urethane primer coat on the surfaces of the plate. |
|

37
We applied
"pale gold" color coat to the plate. |

38
We applied
an acrylic clear coat to the plate and stood it up near the heater
for drying. |

39
We masked
off the board from the rim moulding and applied black stain and
satin lacquer to the inside surfaces of the rim. |
|

40
We lifted the
plate into position and fastened all plate screws and bolts. |

41
We
installed red understring felt. |

42
We placed
the pinblock jack in position under the top treble section of the
pinblock, for supporting it during restringing. |
|

43
We
arranged the restringing tools and put a cardboard protective cover
on the stretcher. |

44
We
polished the aliquots and put the aliquot guides in place. |

45
The top
treble section has been restrung and repinned. |
|

46 - Restringing
is complete, and we have "chipped" all strings close to concert
pitch, so the final tuning before delivery will be relatively
stable. |

47 - We replaced
the odd-numbered shanks and installed new hammers on them. When the
glue has dried, we install the even-numbered shanks and hammers. |

48 - We replaced
the backchecks. |
|

49 - We made a
new keyframe guide and installed it into the keybed of the piano. |

50 - We cleaned
the keys, and replaced several missing and chipped keytops. |

51 - We installed
the odd-numbered hammers and shanks. |
|

52 - We repaired
the keyframe: several glue joints had come loose. |

53 - We filed the
keyfronts so they form a straight line. |

54 - After
cleaning the keyframe and polishing the key pins, we installed new
underkey punchings and cloth. |
|

55 - With lead
weights on the backchecks, we regulated key heights and levelling,
and keydip. |

56 - We rebushed
the balance rail holes of keys that wobbled. |

57 - Several
balance rail holes were too large, so we used a special drill bit to
make a new hole in which we inserted special washers the right size. |
|

58 - We made new
regulating button cloth to replace the worn cloth, and also reshaped
the rail to fit correctly under the new jack tails. |

59 - With the
action on our special regulating table and using the Jaras
Regulating Jig, we conducted a complete regulation of all
adjustments: hammer height & blow, letoff, drop, dip, and catching. |

60 - We installed
new casters. |
|

61 - Regulation
completed! We think the piano will play well. |

62 - We cleaned
the damper guides and installed them under the strings in the piano. |

63 - We cleaned
the "back action" to which the damper wires will be attached in the
keybed, lubricated the springs, and tightened the screws. |
|

64 - We installed
new damper felts to the blocks. |

65 - The back
action is in place, and the dampers have been installed. |

66 - Dampers are
as good as new again! |
|

67 - Although the
strings were pulled up to pitch when they were installed, the pitch
of these new strings went flat by at least a full tone. It will take
at least 3 tunings to bring them up to A-440, and it will take
additional tunings to establish pitch stability. |

68 - We cleaned
and polished the sostenuto bar and hardware. |

69 - We installed
the sostenuto bar and post, and regulated the position of the bar so
it would work flawlessly. |
|

70 - We removed
and dismantled the pedal lyre as well as the trapwork attached to
the underside of the keybed. We cleaned and polished all brass parts
and screws and springs, installed new felt bushings, and reassembled
this part of the piano. |

71 - Using the "Fandrich-Rhodes
Weightbench" computer program and special equipment for measuring
upweights, downweights, and key weights, we analyzed the piano's
touch. We reduced friction where possible by rebushing or
lubricating moving parts. |

72 - Using the
digital analysis of readings, we set the "downweight goal" at 55g at
the bass to 49g at the top treble, and we re-weighted those keys
whose weight exceeded the "target weight" by over 4g--except the top
two octaves which we left unaltered. |
|

73 - We blackened
the lettering on the brand-name embossed on the plate. |

74 - We assembled
and installed the fallboard. |

75 - We assembled
and installed the music desk. |
|

76 - We cleaned
and polished the lid hinges, then assembled and installed the piano
lid and prop. |

77 - We assembled
and installed the music desk. |
