Jeremy I have experienced the same thing on this vintage of piano. Upon closer examination I noticed a lot of key weights in the front of the keys and very little in the rear. I was out of my usual service area and did not have my touchweight tools with me but the touch seemed very light when playing. I am guessing you have a touchweight issue that has been exacerbated by action wear.

The hammers/keys returned to rest very very slowly when the damper pedal was being used, and it was noticeable even without the pedal engaged. Other than newer hammers, it's all original. The hammers seemed a little oversized for the piano. So, I have checked everything: hammer flange center pins and return springs, wippen flange centerpin, jack centerpin and springs, capstans for buildup/residue, keybushings, key balance hole, dampers, everything. No problems with sluggishness anywhere. Each part of the action, the hammer, wippen, and keystick operates fine independently. The hammer/wippen actions operate just fine when you remove the key and push up on the capstan pad. The only problem is when you introduce the key. It really seems like things are binding up at the capstan pads. So, could wear and tear cause the cap/pads to bunch up and throw off the regulation geometry? The cap/pads are pretty worn and "dimpled". Could the larger replacement hammers change the way an upright hammer returns to rest? Did I miss something? The customer probably won't even notice this but it's bothering me that I couldn't figure it out. Thanks! Jeremy -------------- next part -------------- An HTML attachment was scrubbed...
