Kranich & Bach 6'1" Parlor Grand #34410
With beautiful ornate
rosewood cabinet. A "family heirloom," played by the owner's
grandmother when a child at the turn of the century. Built in 1899.
Restored by Ray's Piano Service, March-April 2005.
This was a truly fine
piano when new! Before restoration, it showed considerable wear in
hammers and other action parts, badly corroded strings and pins,
resulting in very poor tune. With restringing, repinning, and action
reconditioning, this piano can be returned to its original playing
condition. Our budget for this project is just under $6,000, including
pick up and delivery. IMPROVEMENTS INCLUDED:
Restring, repinDismantle. Remove strings, pins,
plate. Repair and refinish sound board and bridges. Re-install
plate. Install new strings and pins. Rebuild pedal
mechanisms.
Recondition actionClean and
polish all parts to be reused,
install new hammers, new hammer flanges (shaped to fit), knuckles, damper pads,
wippens (shaped to fit), backchecks, damper lifter felt, rebush
damper guide rails, replace additional defective parts, tighten all
screws.
Complete RegulationInstall new
underkey punchings. Make adjustments to ensure that piano plays like
new: key height, key levelling, hammer blow distance, lost motion,
letoff, drop, backchecks, dampers. Tune to A-440
Complete cleaningClean
the plate rather than refinishing it, to retain its beautiful
original artwork. Also, we clean and polish the cabinet but leave
the original finish which remains beautiful after more than a
century of loving care.

strings and pins are badly corroded and have lost their brilliance
of tone. These will be replaced. We will also replace the pinblock
if necessary. |
|
1899 Kranich & Bach Grand Pictures of the Restoration
Process taken in our
shop: |
|

1 We removed the piano action, the dampers, and the sustain and
sostenuto mechanisms, for storage during restringing. These
components will be reconditioned when parts arrive. |

2 We
removed the bass strings and sent them to the string maker for
duplication. We then removed the tuning pins. |
|

3
After removing all plate bolts and the "stretcher" board at the
front of the piano, we lifted the plate out of the piano using our
ceiling-mounted winch. This will give access to the sound board and
bridges for repairs and refinishing. We found the pinblock to be in
good shape, so we will not replace it; instead we'll order new
wippens. |

4 We
cleaned all dust and dirt off the soundboard and bridges.
Interestingly, the soundboard has no cracks, so no major board
repairs are needed. We scraped the old finish off the board and
bridges, then sanded the surfaces thoroughly and applied sealer and
spar urethane. |
|

5
We cleaned the plate warm water and
detergent, and we removed the original understring felts. |

6
We polished the plate with a commercial cleaner to preserve the
color. |
|

7
The designs on the plate were well worth preserving. |

8
After we lifted the plate and pinblock back into the piano, we
installed the plate bolts and new understring felt. Then we
installed new strings and pins, using a stringing guide prepared
before destringing. |
|

9 "Before"
picture of damper guide rails--several bushings have disappeared and
all are badly worn, so we decided to rebush all holes. |

10
"After" picture
of damper guide rails, treble and bass. All holes have been rebushed,
and we installed new felt for seating the installation onto the
soundboard. |
|

11
We installed the damper guide
rails, the bass strings, and stringing braid. |

12
"Before" picture of the action components--hammers, wippens,
keyframe, keys, and regulating rail. We found the wippens to be so
badly worn that they should be replaced with new wippens. The only
correctly sized wippen available (i.e. having the same distance from
flange center to jack center) is a "Kawai-style" wippen that
requires some reshaping to fit. Similarly, we will need to reshape
the new hammer flanges to fit on the rail of this piano. |
|

13
We cleaned the grime off the old
keys and sanded the wood surfaces of the old keys. Then we cleaned
and polished the ivory keytops. |

14
We replaced the original back checks and damper lifter felts on the
backs of the keys with new ones. |
|

15
After sanding the wood surfaces of the keyframe and cleaning and
polishing the key pins, we "bedded" the keyframe into the keybed of
the piano by sanding the areas that we separated. This is a delicate
task with this non-conventional design of keyframe, because the
balancing rail as well as the front and back rails must all rest
flat on the keybed for minimum knocking noise as the piano is
played. |

16
We
installed new nameboard felt on the edge of the fallbaord which will
be above the keys. |
|

17
With the keyframe, the
end blocks, the keyslip and the fallboard in place, we set the
height of a few low bass keys at the balancing rail and at the keyslip.
We repeated this process at the top treble, and then we regulated
keyheight and levelling for the entire keyboard, with the action on
our workbench. |

18 The
sostenuto mechanism of this piano is of non-conventional design,
consisting of a number of plastic tabs that hold up the dampers by
means of small brass clips installed on the damper levers. We
dismantled this mechanism, cleaned all surfaces, and replaced all
worn felts. |
|

19
The damper mechanisms are ready for re-installation. |

20
The damper
mechanisms have been re-installed in the keybed. |
|

21
We removed all damper felts,
cleaned the damper blocks and wires with steel wool, and sprayed the
wires with silicone. |

22 We
dismantled the lyre; then removed, cleaned, and polished the brass
parts; replaced felts; and reassembled the lyre and re-installed it
in the piano. |
|

23
We installed new felt on the dampers, then regulated each wire of
the bass dampers in order to seat them properly on the strings. Then
we installed refelted dampers at the end of each section. Before
installing the rest of the dampers, we will install the hammers and
align them to the strings. This is important, because the strings
cannot be moved, being inserted in holes in the plate. |

24 The
parts suppliers were unable to provide new hammer shanks and flanges
that fit this non-conventional piano. We selected shanks that would
fit perfectly if we cut about 1/4" off the tip of each flange. |
|

25
We attached a jig to our band saw and cut all the new
flanges. |

26
We used cold
hide glue and our "home-made" glue applicator for installing hammer
heads. |
|

27
We replaced original wippen #88
with a new sample Kawai-type wippen obtained from our supplier. We
were able to make this wippen fit this non-conventional action by
cutting the accelerator spring off the flange. Then we installed new
hammer shank and hammer head #88, aligned the hammer to strings for
note #88 in the piano and adjusted the strike point for optimum
tone. |

28 Our
new hammers were "Abel Lite" hammer heads pre-bored to samples by
the supplier. To save us time, the supplier also tapered the
hammers, squared them to the back checks, and roughed them for
effective checking. |
|

29
We installed the hammers by
section, matching angles and striking points to the samples
installed earlier as well as to a few original hammers that were
correctly aligned to the strings. |

30
This hammer
installation project was complicated by the fact that the shanks
were positioned at varying angles on the rail. We positioned the new
shanks to match the location of the original shanks, correcting
locations after installing hammers at consistent angles. |
|

31
Because of the angled position of the shanks, we found that the
hammers needed to installed at angles that compensated for upward
swing, ensuring that they would strike the strings of each unison
squarely. |

32
We installed
the dampers one-at-a-time, beginning in the bass. For each
installation, we regulated the damper wire, then glued the new felt
pads on the blocks, then inserted the wire in place and tightened
the screw. This was a tedious project, because previous wire-bending
and oversized guide rail holes had left most dampers poorly
misaligned to the strings. |
|

33
We installed "trichord" damper felts in the first six dampers of
the tenor section to ensure efficient muting. |

34
Using the original wippens, which will be replaced with new
wippens when the shipment arrives, we regulated hammer height, blow
distance, and letoff--so the piano plays well enough for us to tune
it. |
|

35
We tuned the
piano several times over a two-week period. When the new wippens
arrive, we will install them and conduct a complete regulation. |

36
We removed the
original wippens. |
|

37 The
"geometry" of the new wippens is correct, but there were two
challenges: First, we needed to cut off the "accelerator spring" to
enable the flange to be installed on the horizontal rail. Second, we
needed to adjust the jack position before installing each wippen
because this cannot be done afterwards. |

38 We
installed the new wippens, aligning them to the knuckles. Those
which needed further alignment to the capstans we angled at the
flange with spacing paper. We also installed a layer of sandpaper on
the rail to hold the flanges snugly. |
|

39 In
order to correct the angle of the jacks, we raised the back rail,
using wood spacers about one-eighth of an inch thick. |

40 We
regulated the jacks before installing each wippen, finding that the
varying angle of the wippens required different jack positions. |
|

41 An
additional challenge was to find the right capstan position because
this affects the touch weight. We will examine this issue after
regulating. |

42 We
discovered that the jacks didn't quite reach the regulating buttons,
so we inserted shim under the regulating rail in order to correct
this. |
|

43
By placing the
regulating buttons on an angle down to the jacks, we solved an
additional problem--this moved the regulating tips away from the
hammer rail to make them easier to turn. |

44
As we installed
wippens, we corrected the angle of the new backchecks and bent them
into place a small distance away from the hammer tails to avoid
hitting them on the upswing. |
|

45
This piano has a very "uncoventional" keyframe: large brackets
support both the hammer rail and the wippen rail, making access to
individual parts difficult. |

46
An additional
problem with the keyframe was the lack of "crown" in its
construction--in fact, there was slight "reverse crown" due to
deterioration. To prevent knocking noises when playing, we installed
thin felt spacers to support the front of the keyframe.. |
|

47 We
cut some wood out of the damper lever support rail to prevent
knocking noises as it was lowered. |

48 We
bent the sostenuto support wire to improve its functioning. |
|

49
We regulated
hammer blow distance, letoff, drop, and catching. We repeated the
regulating process with the action in the piano, and then we
regulated key dip. |

50
We tuned the
piano again, now that we a much improved action. |
|

51 We
re-installed the key blocks, keyslip, and fallboard. Ready for
Delivery! |

52 We
don't often have an opportunity to work on a unique vintage
instrument such as this Kranich & Bach grand. We are very pleased
with the final outcome of the project--so are the owners! |
