  Subject: Slow hammer return


  List,
  I have a customer with a 1921 Steinway Upright with very slow hammer return, which I think was caused by a floor humidifier.  I  heated the hammer butt centers with a hair dryer, which freed up the hammers for about 1 hour. The questions is what do you think is the most reliable way to free up sluggish hammers without replacing center pins or parts?  Should I use silicone and naptha, alcohol and methanol or install a Dammp-Chaser heater bar with a humidistat?

  Thanks,
  Arthur
