Dear Terry, In regards to selling your customer a Precision TouchDesign job (Stanwood action work..). The first thing to do would be to determine the levels of this actions touch weight components. I'm willing to bet, based on what you've shared with us is, that the hammers are too light and too hard. What I consider too light for a Concert Hall grand is anything in medium or low strike weight zones. Harder hammers sound better when they are in the High zone. http://www.stanwoodpiano.com/sw-zones.jpg You mention that this piano might be at perhaps 25% of it's potential. Based on the enormous amount of data that my associate technicians send me, I've come to the conclusion that most pianos are at some fraction of their output due to underweight hammers. For instance, we just had a brand new Steinway D in our shop and it felt fine but the sound was not broad and powerful. It turned out that the Strike Weights were mid medium zone! So we weighted up the hammers by as much as 2.5 grams bringing it to the upper full zone and to a smoothly scaled specification. This made for an incredible improvement to the tone, but of course the action became heavy. So that was solved by moving in the capstan line by a specified amount, adding adjustable helper springs to the wippens, and individually scale balancing each key to a smooth scaled Front Weight, using the patented process. This created an action with balance weights in the mid 50's (Down weights in the high 60's). Finally we hooked up the helper springs and adjusted the final balance weight to 35g, classic Steinway, by turning the touch regulating screw, ending up with final down weights in the high 40's. Loose bridge pins? ... Bad news... That needs to be addressed. David C.
