[pianotech] hammer return noise

[Gerald Groot]

Hi Gene,

 

I haven't had time to read everything but, I haven't (unless I missed
it-probably did-) noticed that you checked the felt that the jack hits upon
returning. If it is worn, hard or compacted, it too, could possibly be the
problem?  Have you doodled around with the jack tender just slapping it back
and forth to see if anything in that area is noisy?  Just another thought.

Is is possible to isolate the key by lifting the hammer and putting some
lead on the end of the key? Then you might be able to tell if it is the the
key which makes the noise by slapping down on the back rail cloth.
Sometimes, a layered back rail cloth can be quieter - you may consider that
if this is the source of the noise.

Jurgen, this is a great idea - thank you. It is on the to-do list for today.

I will post later what was done and if there was any success.

Gene
