Hailun "buzz"

    Would anyone like to try to tackle an undiagnosed "buzz" at B4 on a Hailun 178?  The piano is in Georgetown.  The customer has talked to Hailun, who has promised the customer that they would contact me to discuss the problem.  Any bets on whether they will ever call?

    I've found annoying little buzzes on some of the hardware.  Check hinges and other attached pieces. Very annoying and hard to find sometimes.

    Buzzes are the bane of my existence; everything from picture frames on the wall, to loose cabinet screws, bridge pins, agraffes, Fallboard hinge pins, and peanut m&m's under the plate....
    One sometimes needs a second person to initiate the buzz while you use your stethoscope, mirrors, pushing & pulling cabinet parts, and careful directed listening.

    As always, my thanks to our community for their help.  The customer (an MD) took a week off and tightened every single screw and bolt he could find on the piano, took photos of it all (with notations) and sent it to me this morning.  The buzz was most pronounced in the plate screws "above the serial number" and the stretcher.  Also offending with a different '"buzz" was the hinge pin and the music desk props among others.  I'm glad I didn't have to charge by the hour to find and fix all of those.  By the way, how DO you charge for diagnosing and fixing a "buzz"?

    So.... is the buzz fixed ? If the piano has a lid lock at the top of the stretcher a rattle or buzz can be coming from the inside of the lock and present itself at certain frequencies. Been there and done that. Regarding hinge pins maybe they are a little undersized a small piece of clear tubing may damp the pin enough if it is placed on the visible pins of the hinge pin. Of course the screws on both the lid and rim could be loose as well. If the client followed your directions I would charge a small consultation fee .

    I will mention there is a large screw which connects the stretcher to the rim, (which I recall being somewhat hard to find) and took only a bit of tightening to resolve a difficult, persistent buzzing complaint. I couldn't hear it, truth be told, but the owner (a music professor) certainly did, and his ear guided me to the spot.  Very happy overall with his Hailun, I will add!

    Regarding charging for this kind of thing I will tell the client that I must get paid for the time I spend on this (and that it can sometimes be very complex), there are some things THEY can do as easily as I can, one of which is to tighten every single screw they can find (and get to) anywhere on the piano. Another thing is to remove any object in the room that MIGHT vibrate. If these still don't identify the source of the buzz (or "high frequency vibration") then I can pick up where they left off. If, after an hour or so I still cannot figure it out then we can call in another tech who might bring a fresh viewpoint on the matter.

    This way they understand that this is NOT a free service.

    FYI: Hailun DID call me today and we discussed the most typical "buzz makers."  I repent of my haughty attitude toward Hailun.  The problem, by the way, has been resolved by a dedicated customer and a good set of screwdrivers.
