Why choose us?

Because we have extensive experience in the rebuilding of vintage instruments like Steinway, Mason Hamlin, Chickering, Knabe, Baldwin, and many fine European instruments, because we customize each and every job to your own personal tastes and requirements, and because we will work within your framework and provide the information you need to best achieve your goals. 

Our two primary goals are excellent and expressive tone, and precision action performance.  In achieving those two main goals there are choices to be made:  To put in a new soundboard or recondition the old one, which parts and hammers will achieve the tone and performance goals that you desire, whether to update the engineering and design or keep the original.  It can be daunting for the non technician to understand what all those options are, how the costs compare, what the likely tonal and performance outcomes will be.  We will take the time to make sure you understand all the options, costs and procedures that we propose to undertake to restore your vintage instrument to its original condition using traditional methods and designs or modify it, if you wish, to optimize its performance and customize it to your own tastes. 

Attitudes and approaches vary with respect to how to deal with 100-year-old designs and technologies, and customer goals do to.  While there are many things to admire about the original designs of the so called great pianos, the evolution of the piano did not stop in the early 1900's nor were the orignal intended designs of these pianos necessarily achieved in the factory.  Many of these manufacturers continued to develop new design ideas and today there is a greater understanding of the acoustics of the piano, scale design and balance and the elastic limits of materials used in soundboard construction that effect not only predictability of outcomes but longevity and stability as well.   Options for optimizing designs now exist with the benefit of engineered modeling that can help to predict better outcomes Depending on customer goals and attitudes we can copy original designs, optimize original designs or modify with enhanced performance features.  Whatever your preference, we'll discuss the pluses and minuses and associated cost and help you make an informed decision.

Rebuild or buy new?

If you've recently ventured into a new piano showroom you can easily feel and hear the great variation in touch and tonal output even between pianos of the same make and model.   These differences are sometimes attributed to such things as "each piano's individual personality".  Often it reflects the inconsistency with which some pianos are produced.   Through years of experience we have found that successful tonal output and precision action performance can be controlled consistently by carefully analysis and engineering and controlled manufacturing and that's what we do.  We can maintain those aspects of the original design that defined the tonal character of the piano to begin with and then engineer each detail of the piano's design to create balance and uniformity through the scale enhancing the full dynamic range of the instrument.  We think that a properly rebuilt piano can be, and often is, better than a new piano.  As much as the original design allows we tailor every aspect of the piano to your own personal taste, that includes both tone and touch and we can usually do it for less than the cost of a new one.   
  
A typical restoration package

Soundboard

When installing a new soundboard we analyze and engineer each one for optimum performance.  Optimizations to the original execution are sometimes made when we find the factory did not achieve what may have been the design goal.  If the original soundboard still maintains enough structural integrity we can and do recondition the panel to enhance stiffness in critical areas, resurface, repin and renotch the original bridge or install new bridge caps if necessary.  All soundboards, old or new, are finished with traditional hand rubbed varnishes. 

Scale

Each scale is analyzed and recalculated to insure accuracy of execution and smooth tension, inharmonicity and impedance curves for improved tonal balance.  

Bridges

Bridges are either recapped or remade to accommodate the existing or optimized scales.   Original bridges are routinely resurfaced, repinned and renotched to insure clean and solid terminations.

Pinblock

For most restringing and all soundboard replacement jobs, we make, fit & install a new pinblock.  On occasion the original pinblock can be reused but we do not recommend reuse for more than one restringing and then only if it is uncontaminated and structurally sound.

Plate 

Plates are carefully cleaned, filled and sanded prior to refinishing.  All agraffes are replaced, shaped and carefully polished.  Counterbearing areas are analyzed for proper angles, reshaped, redesigned or replaced.  Plates are refinished in gold and bronze lacquers with a protective clear coat.  Lettering and plate decals are replaced as is consistent with the original design.  Plate mounting systems and support dowels are typically upgraded with a modern plate suspension system that allows for fine adjustments of the plate height for more accurate downbearing settings. 

Strings & Tuning Pins

Treble and bass strings are replaced with the highest quality wire available.  Each set of bass strings is custom measured and ordered to insure absolute accuracy.  We use Roslau Premium Wire in the plain wire section.  Bass strings are custom made by the JD Grandt company to our specifications.  We prefer traditional blued tuning pins but can choose nickel plating if the cosmetic requirements of the instrument or the customers demand it. 

 
Action Parts and Hammers

We use the highest quality Renner action parts whenever possible.  Hammers are chosen based on the tonal and performance requirements of the piano.  Selecting hammers is a critical part of the rebuilding job and we take special care to sample a variety of hammers to insure that there is a good match between string tensions, soundboard response, and hammer firmness and resilience. The hammers we most often use are:   Ronsen Special Weickert Felt designed to our own custom specifications and various Renner hammers
.  Each hammer is custom designed or selected based on tonal requirements first. 

Each action is then individually analyzed for leverage, inertia, geometry and alignment, weight and balance, regulation, friction and damper action interface.  Action parts are then selected in conjuntion with the hammers to provide optimum balance, touchweight, and inertia.  The dynamic balancing of the action is of paramount importance and issues of inertia are given strong priority in the selection of action parts to accompany hammer weight.  All actions are custom designed to satisfy the individual player.
 
New keysets can be made when needed and legal, prebanned, one-piece ivory key covers are available upon request. 

A complete action rebuilding includes changing not only the major action parts but all action supporting felts, backchecks, leather, key bushings, etc.  The action is fine regulated in the piano and installation includes a regulation follow up after the action has been adequately played in.     

Dampers & Damper Action

We make and install a new Renner damper tray assembly with underlevers when needed.  The damper tray is typically modified with a fine adjustment capstan for each damper underlever for more accurate regulation. 
Damper heads are cleaned, sanded and refinished or replaced if necessary. Guide rails are sized, refinished and rebushed.  Damper felts are custom cut from the highest quality felt.

Lyre, Pedals & Trapwork                                                          

All felts and leather for the lyre, pedals and trapwork are replaced.  Older  non adjustable pedal rods are replaced with adjustable type.  Pedal geometry is analyzed and corrected if needed and trapwork interface with the action is often modified for greater pedal efficiency and to control unwanted noise. 

Casework & Finish 

All finishes are done with the highest quality traditional, hand rubbed, lacquer.  We work with you and the finisher to achieve the color and sheen that you desire.  We manage all refinishing jobs from beginning to end.  All hardware is polished, replated or replaced as needed.
