Richard First, no I will not be in Colorado this winter. Our son and his family are coming here to sunny and warm Hawaii for a week around Christmas Regarding the bobbling,?on one of the D's, no matter what kind of blow I did,?some hammers just wouldn't check, mostly in the 2nd and 3rd octave. On the other D's, I finally got them to check, to some degree, by severly roughing the tails.?

Tom, the piano is c. 12 years old, is a teacher's piano that has had a lot of use from advanced students.? I regulated the action (blow, let-off, rep sprgs, key level/hgt, backchecks, etc.),? filed and voiced about 9 months ago. No parts have been replaced, just reconditioned. ? Backchecks are in good shape.? I did not give any attention to the balance hole, so I need to look at that. This is not a backcheck issue, because the bouncing happens on a sharp, staccato blow that does not put the hammer in check.? Wim, it sounds like you are describing the problem that occurs with a soft/med-soft blow.? (Aloha!? I am happy for your new venture.? Will you be skiing in Colorado this winter?)

A combination of roughing the tail, making sure the rake and the angle is right on the back check,?and reducing the rep spring to where it just barely holds the balancier up to allow the jack to return, will take care of most the bobbling. It was suggested that the wippen flange and the balancier pinning might be the culprits,?but after reducing and then increasing the pin size,?I don't think it made any difference. Then I read somewhere that some bobbling is allowed, and not to worry about it, at least on a D, as long as the hammer isn't bouncing up and hitting the strings.

This is not the bubbling/bobbling hammers that can happen with a soft blow, but a rebound from the rest felt that restrikes the string on a sharp staccato blow.? The hammer flange pinning is a bit loose at 3-4 grams (7-8 swings), but I don't think that is the whole problem.? Anyone encounter a similar Schimmel problem?
