---------------------- multipart/alternative attachment Thanks, Ed, for your insightful comments. I am going to have to read, reread, digest and try these things when I'm back at the piano next week. I know the pinning on the new hammer flange is correct - it gives 5 swings. The new shank and flanges are Renner, the one they list for Hamburg D. The new hammers are Hamburg. They are maple instead of mahogany and wider than the old (the old are original I think). Mr. Kalb of Hamburg Steinway said they changed to the maple about 4 years ago. I have also tapered them. The old hammers are glued onto the shank at a distance shorter than the Hamburg spec of 130 mm. perhaps because they sounded best at that distance in the high treble. They are glued on at about 128 - 129 mm. Going back to my original question about hammer bore distance affecting the performance of the action, it seems that you are leaning towards other causes of the slow repetition more than the change in bore distance and its impact on knuckle/jack/wippen center relationship. One puzzling thing is the comment about Roger Jolly's labeling of aftertouch as anathema to repetition since the key had to travel through it before things can reset. Do you think that .050 aftertouch is beginning to be too much for that reason? Interesting that you mention Ravel and repetition speed. We were taking my son to piano competitions at various universities this year playing Ravel's Gaspard de la Nuit, "Ondine" for one of the pieces. A few of the university's recital hall pianos would allow him to do the fast repetition cleanly and as quickly as he wanted while others made it come out uneven and sluggish.
