Dear Friends, I recently tuned a nice Baldwin Artist grand, about a year old. I also tightened all of the plate and action screws, including the damper flange screws. During my tuning, I noticed that two dampers were sluggish in returning, so I worked to get them to stop sticking, and they were working when I left. The customers were pleased with the tuning, but noticed several dampers being slow in returning after I tuned the piano. The customer thinks that it had something to do with the tuning. I don't think it had anything to do with the tuning, but it MAY have something to do with my tightening the damper screws. I have a chance to go back and correct this problem on Wednesday. I am thinking of lubricating the sluggish damper wires with Protek, and possibly reaming the guide rail bushings. Are there other things to try? Also, can sluggish dampers have anything to do with the humidity? Some days the dampers stick, and other days they don't. Do guide rails change that much with the humidity? Thanks! David David A.
