Diagnosing A Sticky Key
The trouble with diagnosing a viscous is that there could exist one thing causing the problem or it could be the upshot of several things. Either way, follow this process to begin.
Beginning At The Front end Of The Key & Bank check The Key Skid
To begin, start at the forepart of the offending key. The starting time affair to check is whether the white central is too shut to the fundamental slip. This volition only be the case if the sticky key is white, because the black keys do not touch the key slip.
The key sideslip is the board that sits in front of the keys. There should exist room for the key to exist pressed downward and and then let upwards without ever touching or rubbing confronting the key slip in front of the key.
Expect down in between the key and the key slip. Tin can you see infinite there? There should be several millimeters of space. If you can stick some paper or a paperclip in between the central and the cardinal slip, then that's non the trouble.
If the central is currently stuck, endeavor gently pulling the fundamental skid abroad from the central. If the fundamental comes unstuck, then the fundamental sideslip is the problem.
This usually happens if the piano is existence stored in high humidity. The forest of the fundamental slip can swell slightly, which causes the central sideslip to expand and printing against the keys. It is as well possible that the player or somebody in the house leaned too hard on the key slip and warped the central skid slightly.
Cheque The Central Itself
The next affair to check is the fundamental itself. If the piano has been stored in high humidity, it is possible that the keys are swollen and are now pressing confronting each other. This will only happen to piano keys that are fabricated with woods.
Take a thin, flat tip screwdriver and come across if gently separating the sides of the keys gratis the key. If so, the fundamental may be swollen. Be actress careful doing this to blackness keys, as they tend to exist more fragile.
Cheque For Trash Or Debris
It's of import to cheque for trash, crumbs, or other droppings in the between the keys and underneath the keys. This is especially true if the piano is being played by children – I vividly remember dropping several pencils into my piano as a child and having to somewhen call a piano technician.
Check between the keys with a thin, apartment screwdriver, newspaper clip, or screwdriver. If you notice an object between the keys, try to remove it, either with your tool or with a tin of compressed air.
Y'all should as well check nether the keys. This requires a little more piece of work. You need to remove the lid, remove the music shelf, and remove the fallboard and autumn strip – this is non as hard equally information technology sounds, just be careful to continue the screws with the appropriate parts.
Once disassembled, wait above and below the keys. Press down and elevator the sticky key and run into if at that place is anything obvious causing the trouble. Newspaper clips, coins, pencils, food, and sheet music are all mutual culprits inside pianos.
Bank check For Corroded Rail Or Balance Pins
Diagnosing a corroded front rail pin or remainder rail pin is relatively simple. You lot must remove the key and impact the pins. If they are polish, then the pins are not likely to exist the issue. If they are crude to the touch, they probably have a niggling fleck of corrosion on them.
If this is the instance, yous can probably use metal polish to smooth and polish the pins. Once they are polish, the key should move easily up and downwards on the pin. Yous tin can picket this video for a guide on polishing rails and remainder pins yourself:
Checking The Jack Flange
The jack flange is a mutual culprit for sticky keys. The jack flange is a role of the action – the mechanism that causes a hammer to hit a string when a primal is pressed. The whippen is the office of the action that sends the hammer towards the strings – the whippen has a jack and a jack spring.
If the jack spring is broken, the jack won't be able to render to its position properly. More likely, the culprit is the jack flange.
The jack flange can come unglued. Await at the activeness around the hammer and check all the glue. Does the glutinous key look different from the others? Is the glue bereft? If the glue joint breaks, the jack volition exist out of place and the key will stick.
Likewise mutual is a tight jack flange. If the note plays fine sometimes but occasionally gets stuck and won't play, it's probably a tight jack flange. The trouble will usually exist worse with the damper pedal down. Concord down the damper pedal and play the annotation over and over – meet if you tin get the note to stick.
The pin that holds the jack to the flange goes through a pigsty with felt in it. The felt tin swell and cause the pin to be too tight. The same matter can happen to the whippen flange or the hammer flange.
Check The Key Bushing
One of the more than mutual reasons for viscous keys is wet in the key bushing. Keys are guided upwardly and down by ii metal pins that extend up from the key bed. There is also a thicker guide pivot about the front of the fundamental which keeps the key from wobbling. Both pins are lined with a thin felt bushing cloth.
When this bushing cloth becomes likewise moist or humid, it volition corking, and this will crusade the guide pins to be too tight on the keys. This can happen to brand new pianos if the humidity has changed from the show room to the house.
If you lot believe the key bushing is the problem, you may desire to call a piano technician. They can remove the central and apply a special tool to compress the felt to the appropriate depth. Sometimes, they volition supplant the bushing entirely, in which case they demand to apply special animal hide gum and position the bushing properly.
This is a job often left to the pros, only there are tools y'all can use to iron the felt and do this yourself.
Fixing The Sticky Key
We take gone through a fractional list of the things that cause sticky keys. Of course, there are other things that can go awry and crusade pasty keys (broken parts, broken springs, etc.) but what I take listed above are the most mutual reasons for viscid keys.
Fixing a sticky key comes down to how piece of cake the problem is to fix and your condolement level fixing it. Some issues are easy. Others crave more work and cognition.
Fixing A Swollen Primal Slip
If the primal skid is the problem, this is something y'all tin can probably fix yourself. Hither is how to fix a swollen or warped key slip that is pressing confronting the keys.
Take the key sideslip off. There are usually screws underneath the key slip (you'll have to go under the piano and wait up), which you lot can take out. The key slip should come up off. And so, y'all demand to brand a little shim to move the fundamental slip out and away from the keys.
Y'all can make a shim out of a bit of cardboard or some folded up newspaper. Business cards piece of work well. Place the shims on the low and high ends of the piano and then adhere the primal slip again. There should now exist infinite between the slip and the keys.
Removing Junk In The Piano
If the cause is junk in the pianoforte, you can diagnose and fix the problem at the same time. Remove the lid, remove the music shelf, and remove the fallboard and fall strip – this is not equally hard every bit it sounds, just be careful to continue the screws with the appropriate parts.
Once disassembled, wait above and below the keys. Press down and lift the sticky fundamental and meet if there is anything obvious causing the problem. Paper clips, coins, pencils, food, and sheet music are all mutual culprits within pianos.
Use a pocketknife to dislodge anything between the keys or compressed air to blow away anything underneath the keys or inside the pianoforte. If the item is big, just use your hands. You lot may have to get artistic!
Fixing Corroded Rail Or Balance Pins
If the rail or balance pivot is corroded, yous need to accept a metal smoothen to the pins and make them smooth once again. To do this, y'all need to remove the cardinal completely.
To remove keys, you need to remove the key slip on the piano. On upright pianos, you lot remove the cardinal slip with screws attached to the bottom of the piano. So, y'all need to remove the autumn lath, which is the board behind the keys.
In that location will be one more lath called the retaining lath that is holding the keys in across their middle section. Information technology is usually held in place by screws at either end – if yous've taken off the key slip and fall lath, removing the retaining board is like shooting fish in a barrel.
Then, you should be able to lift the key off the guide pins and polish the pins until they are smoothen. Follow these steps in reverse social club to reassemble the piano.
Fixing Swollen Felt On Bushing Or Flanges
If you accept determined that the crusade of the sticky key is due to swollen felt on the bushings or in a flange somewhere, this is probably time to call a piano technician. They will remove the primal and employ a special iron to shrink and reform the felt.
Sometimes, y'all can free the pin by mitt by moving the primal laterally back and along. To exercise this, you volition have had to remove the primal slip, autumn lath, and retaining board as mentioned above.
Once you elevator the key, gently move it dorsum and along against the pin to compress the felt. The bespeak is to compress the felt, not warp the wood, so exist careful. Attempt iii or 4 times and if it doesn't piece of work, yous should phone call a professional.
In desperate situations, yous could try taking a hair-drier and blowing information technology laterally across the keys and primal slip for a few minutes. Sometimes, this volition dry out the felt and free the key.
Preventing Sticky Keys
It should be said that many of these problems can be avoided if the piano is stored and maintained properly.
If possible, the pianoforte should be kept on an within wall and so that the temperature does non change. Large changes in temperature volition cause the wood to warp over time. The pianoforte should be moved as footling as possible, both to preclude temperature alter and to prevent mishaps.
You lot may have to install a dehumidifier in your room or piano. Ask your pianoforte tuner about whether a dehumidifier within the piano would piece of work for you – this is the number one cause of sticky keys and problems with pianos, and the solution could exist that uncomplicated.
Do not allow students or kids to put any liquids on your piano. Continue nutrient away from the pianoforte as well. Go on pencils in a jar, and so they exercise non roll into the piano, and effort to keep paper clips in a jar as well.
Taking these precautions volition save you a headache in the future. If you are getting regular maintenance and treating the instrument with care, you volition not take many problems.
