Piano moved in another room - bushings tight!

[A440 Piano Service]

Hello List,

A customer just called and since she lived nearby, I went to see the piano right away. She complained of certain keys so tight that her daughter, the player, couldn't push them down. I inspected and verified the symptom. The problem seems to be that some, 6 total, of the keys' bushings are now extraordinarily tight. So I'm in the process of rebushing them right now.

What I want to know is why? What you might need to know is that about a week or so ago they borrowed my 4-wheel dolly to move the piano to another room while carpet was being replaced in its home room. This problem exhibited itself when the piano was moved back. It was working fine before they moved it.

What happened? Why just "select" keys? And should I recommend then that I re-bush the entire set?

Kinda makes me go, "hmmm."

Thanks in advance Sender: Avery <avery1 at houston.rr.com>

      John,

      No matter what the problem is/was, why are you rebushing? Why not just ease the affected keys?

      Avery,

      I tried that first. I mean these bushings are TIGHT.  I wonder if they could've bent rail pins, too, somehow in the move?  But they looked so CLOSE together that I thought I'd best try easing them first.  That gave SOME relief but they were still sticky, so I'm rebushing half a dozen of them.

      Thanks.

            Hi John.

            Could it be that your customers also renewed the plaster on the walls ? I experienced that when renewing plaster, hygrometry can go wild. I mean, wild. And stay wild for some time.

            Best regards.

            I don't know but I'll certainly ask.

                  Last time I had a similar complaint I found out that the piano made a stop-over outside for two days before being moved back into the original room.

                  Another "tight key" problem from a move turned out to be a jammed key-slip up against the keys.

                  I'll ask about that, too.  Not the keyslip -- 5 of the keys are sharps!!

                  Thanks, guys.  Keep those speculations coming.  I'd really like to figure this one out!
