Richard, This is exactly what started this thread, and after my visit with Eric Schandall and repinning to 4 grams with higher checking things are working wonderfully. Fred said 1-3 grams, but Eric told me "No less than 2, no more than 4". Also, they are making the tails a bit longer and want higher checking. It doesn't hurt repetition. It helps it. The key seems to be to pay careful attention to the rep spring strength. No bouncing, jerking, etc. but a firm rise w/o a jump.

West Sent: Tuesday, October 28, 2003 7:14 AM To: College and University Technicians Subject: Re: Pinning and Tone The question I have about the new Steinway pinning philosophy is: How do you regulate hammer rise and checking. With an overly free flange, the repetition lever spring is hard to adjust It has to be strong enough to hold the rep lever in a stable position above the jack for good jack return and for a good hammer line. But that means the hammer riser is too fast because of the loose pinning, creating problems with double strikes and poor checking on a soft blow. It's possible to compensate by setting drop low to prevent double striking and setting the checking distance closer to catch the hammer higher. But setting the drop low works against good repetition and setting the checking high reduces power. Both are more difficult to set and, I think, less reliable over the long run. To review what some seem to be saying over the past few weeks, does all this mean I'm going to have to repin all new Steinway flanges? Worse yet, do I have to weigh off new actions because the factory weigh off was done with loose pinning?
