Haynes Piano Manual back cover

To clean under the keys of a piano, a technician must first carefully disassemble the piano to remove the keys. With the keys removed, the technician uses a vacuum and brush to remove dust, fur, skin flakes, and other debris that has accumulated underneath the keys, often over decades. Once the keybed is thoroughly cleaned and any damaged felt parts examined, the piano is reassembled so it can be enjoyed cleaner than it has been for years.

Technical Info 9 re-felting keybedDavid Boyce

��

The keybed felts of a piano become thinner and harder over time from use. This causes unevenness in the height and depth of the keys, affecting the touch and appearance of the piano. Refelting the keybed replaces the worn felts and restores a uniform touch and level appearance to the keyboard. It is best done by a professional piano technician, who can remove the old felts, measure for replacements, and regulate the action for even key dip and height. Additional repairs may be recommended during this process to fully restore the piano's performance.

Technical Info 10 rebushing keysDavid Boyce

��

The key bushings in a piano are felt pads that keep the wooden keys moving smoothly on their pins, similar to how piston rings allow pistons to move effectively in an engine. As bushings wear out over time, keys become loose and wobbly, degrading the piano's feel and sound. Replacing worn bushings requires carefully measuring existing bushings and pins to select replacement felts of exactly the right thickness. A technician will then glue the new bushings in place using specialized tools and techniques to ensure a precise, snug fit that restores the piano's touch and tone.

Promo 11 bass string replacementDavid Boyce

��

One characteristic of great-sounding pianos is a rich, vibrant bass produced by long, heavy bass strings under high tension. Over time, as pianos age, the bass strings deteriorate and the tone loses luster. Replacing aging bass strings with new, custom-made strings can restore the piano's bass tone. The process involves removing the old strings, sending them to be duplicated, and installing the new strings, which may take a day if measurements are available or longer if new measurements need to be taken. Related repairs like replacing the bass bridge and dampers should also be considered to maximize the results of new bass strings.

Technical Info 7 CA Glue treatment of wrestplankDavid Boyce

��

The document discusses applying cyanoacrylate (CA) glue to loose tuning pins in a piano pinblock to improve pin tightness. CA glue swells and stiffens the wood fibers around the pins, improving torque. The treatment involves applying CA glue with an applicator around each pin. Results are seen within minutes as pins become much tighter. The treatment enhances tuning stability and makes the piano more enjoyable to play.

About tuningDavid Boyce

��

Tuning a piano involves adjusting the tension of each string by turning tuning pins to alter the pitch. Over 200 strings must be tuned to produce the 88 notes of the piano. While Pythagoras discovered mathematical ratios for musical intervals, these do not perfectly align when stacking intervals and result in frequencies that do not double as expected when moving up octaves. To remedy this, piano tuning employs equal temperament where the intervals are slightly altered to allow all the notes to fit within a consistent scale.

Technical Info 12 keypin replacementDavid Boyce

��

The document discusses replacing keypins in a piano. Keypins help keep keys aligned and allow for smooth movement. When keypins become corroded, they cause unwanted resistance and wear down bushings. The summary discusses removing old keypins, measuring and installing new ones, and complementary repairs like replacing bushings and leveling keys. Replacing keypins can give keys a new feel and improve piano performance.

Butt spring replacement europeanDavid Boyce

��

This document summarizes the process for replacing hammer butt return springs on an 1880s Bechstein upright piano. It describes removing the broken spring from the hammer butt by prying it out with tweezers. Then, a replacement spring of suitable size is selected and its long tail is fed through two holes in the hammer butt and pulled firmly through. Finally, the excess length of the tail is clipped off and the spring is flattened against the side of the hammer butt.

Newsletter 18 worn sharps keysDavid Boyce

��

The document discusses options for addressing worn sharp keys on a piano. It may be best to replace sharp keys that are deeply worn, while refinishing is an option if the original ebony or pearwood keys are in good condition. Ebony is very durable and resistant to wear, so refinishing original ebony keys preserves the piano's history. The procedure for replacing keys removes the sharp from the keystick and glues a new sharp onto the stick. While plastic is most common, ebony replacement sharps provide an authentic look, though at a much higher cost.

Newsletter 17 brass rail repairDavid Boyce

��

Brass rails and butt plates in upright pianos often break down over time, causing notes to stop working. Common problems are broken butt plates and cracks along the tongue that holds the hammer assembly. These issues can be repaired by replacing individual broken parts or the entire brass rail assembly. Small repairs can be done on-site, while larger jobs require removing the action to the workshop for thorough inspection and repair. Replacing worn parts restores the piano's functionality.

Technical Info 16 Repinning & RestringingDavid Boyce

��

Piano tuning pins can loosen over time as the pinblock dries out, causing notes to go out of tune quickly. Strings also deteriorate with age and humidity, leading to poor tone and frequent breaks. Repinning and restringing replaces both with new tuning pins and custom-made bass and treble strings to restore a piano's stable tuning and best sound. The process is labor-intensive but provides benefits like enhanced performance that outweigh the costs.

Newsletter 24 upright hammer replacementDavid Boyce

��

The document provides information about replacing worn hammer heads on an upright piano. It explains that over time, the felt on hammer heads deteriorates as the strings cut into it, producing a harsh tone. Replacing hammer heads with new, custom-made ones can restore the piano's tone. The process involves carefully measuring and duplicating the angles and positioning of the original hammer heads to ensure a proper fit and tone. Installing new hammer heads correctly requires more than just gluing them on and involves precise preparation, placement, and adjustment of the hammers.

Newsletter 19 upright damper feltsDavid Boyce

��

Dampers are essential components in a piano that stop the strings from vibrating after they are struck. Worn dampers do not stop the strings quickly enough, causing unwanted ringing and buzzing sounds. Replacing old dampers involves carefully removing each individual damper and installing new ones so they precisely match the strings. The repair is usually done with the action in the piano to ensure proper alignment as the glue dries. Additional repairs like restringing or regulating may be done at the same time since the action is already out of the piano.

Technical Info 15 wrestplank replacementDavid Boyce

��

The document discusses replacing a grand piano's pinblock. It explains that a pinblock must grip tuning pins tightly to maintain tuning, and deteriorated pinblocks can cause tuning instability. Replacing a pinblock is often best when laminations have separated, pins are loose, or the pinblock is mushy. The process requires removing the plate and precisely cutting, fitting, and drilling a new pinblock to the plate to ensure tuning stability. The level of precision makes replacing the pinblock best done by a technician rather than at home.
