Hummm ... Today I had a older church Steinway that a few years back had some hammer reshaping and regulation work by a legitimate tech, but now the upper hammers (oct. 4 and upper have about 20 hammers that do not go into check but rather strike the string and then drop very slightly but even under a hard blow will not lower anymore than perhaps 15mm (not enough to check). I measured the hammer blow distance seemed correct, the let-off and drop seemed not bad and the general keydip across everything seemed also correct. I did not have time to get too involved but want to come back later to resolve this issue. Maybe someone else has seen this happen????? I'm hoping there is a simple solution to what may have happened. Is this possibly due to: (a) Repetition Springs to strong on those notes (maybe after filing the hammers) (b) gunk maybe preventing repetition spring from proper flexing in the groove (c)keydip or bedding screws may have changed after time (d) the whole regulation maybe completely off even though the measurements seem not bad (e) all the above (f) tell the customer to donate this piano to charity and buy a new one! I guess I can try to mal-adjust my model to see if I can get it to do this but I hope some one may know just what this is!
