Suggestions to repair Upright clicking noise

    I am seeking input for some ideas on where to find and/or repair clicking sound in the action of a Wagner upright piano. Based on Piano Atlas it was built circa 1920. Without being redundant based on your experience, I would like to provide some background of my experience with this action.

    At the initial tuning, clicking was prevalent only in the 2nd and 3rd octave however Protek seemed to help that time. Subsequently, at a later tuning, the piano owner marked multiple keys that were clicking. I removed the action to take home to my work shop. At that time, various keys in the 3rd thru 5th octaves had clicking. Thus, pivot points, jacks, hammer butt as well as each note felts were slightly fluffed up with a voicing tool, changed the bridle strap plus wire adjustment, etc., etc. In summary, a colleague in the area, coached me on this and more processes. In addition, I have referenced Reblitz. Results had no significant change. Now is repair has become personal, frustrating, and embarrassing.

    Any suggestions or what am I missing?

    Hi Garry:

    We've all been there.  No need to beat yourself up.  You've done the right things so far. 

    Clicks in the action need to be isolated.  When does the click happen?  Is it on the initial blow, or as you let go of the key?  Sometimes on the strike of the hammer there's a clicking sound due to a loose hammer head.  Most of the time I find that I can feel it loose on the shank.  The sound will be kind of "woody" and the crisp sound of the string is absent. 

    If the click happens when you release the key, it might be missing the felt on the hammer butt.  It's also possible someone installed fresh felts and the glue saturated the felt, and the click is the jack hitting the glue.  You never know who did what on the action when it's that old. 

    Check all the glue joints, even the catcher on the butt can be loose and make a sound.  Tighten all the screws that you can find.  Are the hammer flanges tight?  Anything loose at all can cause noises.

    Assuming that you tightened all the action (flange) screws and the hammer shanks aren't hitting the hammer spring return rail. Are you sure the sound is coming from the action? Sometimes the name board felt wears away and the keys knock against the hold-down rail upon release. Other than that, all the stuff Paul mentions. Maybe the problem gets worse seasonally? Loose ivory tails can click too.

    One of possible sources of clicking is catcher wire interference with neighboring bridle strap wire

    If the clicking noise is when the hammer hits the string then the clicking is a loose hammer head. Turn the action upside down and add several drops of CA glue to the hammer joint.

    I once traced this problem to a loose keytop! Just an oddball idea!

    If you can take a video, that would be helpful to help us figure it out for you.

    Mr. Greene,

    I have a video for you to review however software programs have changed to a point I have not been able to figure out how to attach. If you have a different email that I can sent it to, let me know. Please excuse the delay in responding to your request as it was a challenge meeting up with my customer and getting the pdf image attached. I am seeking input on how to resolve/repair clicking the action of this Wagner upright piano. Based on Piano Atlas it was built circa 1920.  I would like to provide some background of my experience with this action so you have some idea of what I have done so far.

    I have tuned this piano at least 4 times. Initially I had not noticed any clicking when tuning. This piano had most of the bridle straps were broken or decomposed due to age. The first tuning turned out ok after many years of neglect. Subsequent tunings I noted some clicking was prevalent only in various 2nd and 3rd octaves, applying CLP to the joints seemed to help that time. However, at a later tuning, the piano owner marked multiple keys that were clicking. I removed the action to take home to my work shop. At that time, various keys in the 3rd thru 5th octaves had clicking.

    Thus, pivot points, jacks, hammer butt as well as each note felts were slightly fluffed up with a voicing tool, changed the bridle strap plus wire adjustment, changed the hammer rail felt, etc., etc. In summary, a colleague in the area, coached me on this and more processes. In addition, I have referenced Reblitz. Results had no significant change.

    As you will see in the video, clicking appears to occur after releasing the key and the jack hits the hammer felt butt. Is it possible I have the bridle strap too taunt? Do I need to replace all 88 butt felts?

    This repair has become personal, frustrating, and embarrassing. Any suggestions or what am I missing?

    Cordially,

    Garry

    I like to call these a "count your blessings" type of situation.  Most pianos that can even make it that old are lucky to be playing or even tuneable at all. Thankfully this is pretty much to be expected from action parts this old - so the good news is you don't have to worry about trying to fix it LOL.  I encourage people to let me update their action to all new parts when their piano is older than 70+ (usually WNG performance carbon composite parts). This is really the only way to ensure no more clicks and a beautifully silky action that will play like butter.  You could treat ALL the action glue joints, which I have done before, but at the end of the day you still have 100 year old parts that will not perform that great regardless of clicking noises, and you will still probably have clicking noises in most cases.  And as the weeks and years go on the parts are only getting older and will continue to get more worn out and increasingly more clicky. When your tires get bald they will still take you to the store.  Actually even after your tire has blown you can still get to the store, though ride quality will be affected.  Time to change tires 😉

    You can let them know that this is the best it can be until they or someone decides to update the parts - which it was overdue for 30+ years ago. Turn and burn.  It sounds like you improved their piano overall😀🎹🎹🎶

    Gary,
    Do you remove the key cover when tuning?
    Sometimes a key cover can slide enough toward the action that the back checks will hit upon the key release.

     A Few postings here have touched on the age of these "old upright pianos" and made me stop and think a bit (I know, a dangerous situation).I started  working on pianos (my own player, and my family's piano) in 1970 and then became a tuner-technician in 1977 (old school name for our profession). Back then that family piano was 53 years old, and now it's 107! YIKES! My player was 63 in 1972 when I got it, and now it's 115 going on 116. My other three personal players are now 108, 102 and 93 years old. Yikes! When did I get this old?? Come to think of it, when I started restoring my Model A Ford car, it was 39 years old and considered an antique (although a few people were still driving theirs as just a used car) And the truck I drive regularly is now 21 years old, and considered still "modern (and pretty much still has all the parts on it from the factory)." Heck the Prius we have is 20 years old, and I think of it as our "new car."

    So no wonder we are having problems with these old pianos, and that includes pianos made in the late 1970s. (lots of YUCK pianos made then!) The times, they have moved on!

    Another item of interest might be checking the leads in the keys.
    They might need to be re-swedged.

    First tighten all action screws, check for loose hammer heads, check clearances of backcheck and bridle tape wires. Next thoroughly check keyset for clearance

    issues and loose keytops including sharps.

    With a piano that old, and in this dry weather, there may be multiple loose glue
    Joints. And there are a lot of joints.

    Tap with your finger on the tip of the ivory tail (assuming this has ivory). If it clicks when you tap it, you've found a good candidate.

    I assume you’ve tightened every flange screw on wippens and hammer butts?

    Another possibility, since you asked if you might have to replace all 88 hammer butt felts:
    Maybe try replacing one and see if that helps. It’s possible that someone replaced them in the past but either used a thin glue that soaked the felt or got some glue on the front where the jack hits. The jacks can make a click if they hit a bit of glue or a hard felt—I’ve seen it before.

    I once had a newish Baldwin Hamilton that had a click/rattle from the keys.  When you let go of the key, it would make a sound. The key would bounce and make a loud sound that was quite annoying.  Whether you could call it a click I don't know.  The balance rail hole was not chucking or loose, but was free enough that when you drop the key onto the pin, it would fall without resistance.  I tightened the fit by shrinking the hole to create some friction with the pin.  This worked.  On an old piano, it is quite likely to have enlarged bal rail holes.  The Baldwin was near-new, so I was able to close the hole somewhat by rubbing a screwdriver blade across the hole.  Glue-sizing the hole would probably work better.

    PS. There's an icon above the post I"m writing that looks like a movie camera, and if you click that you can post a video file.  Should work.  Or upload it to Google Drive and post a link to it.

    Mr. Gambill-

    What you have missed is a basic principle of good work: "Diagnosis before Treatment!"

    Diagnose an action problem by starting at the front of the key and working through the action, one point at a time. Is an individual piece loose and rattling, such as a key cover or capstan? Are parts knocking when the note is played, such as a key mortise against a key pin or a bridle tape wire against a back check wire?

    If neighboring notes are clicking, look for a neighborhood problem such as a wandering rail or case part.

    The piano is in front of you. You are the one person who can solve this problem. Start at the front of the key and work through the action, point by point until you find the cause.

    It's worth noting that when Reblitz first wrote, a 1920s upright piano was about 50 years old. Today it is twice that age.

    Repairs that made a difference on a 50 year old piano may not be so useful when that piano is 100 years old.

    There will be many things on a 100 year old piano which "could be fixed," but that's probably not an economical approach.

    If you can find the issue that is bothering the customer, maybe you can fix it. Chances are the customer is used to many issues that would bother a pianist who normally plays a better piano. 

    "Last week my mother was happily playing Beethoven on this piano, which she's played since she was a little girl. How can you dare to tell me it has no retail value?"
