I discovered = that the shank lenght was too long.=20 I now have a similar problem with a D. But this time, I've rebuilt the = action with new Steinway parts, (new h,s,f and wipps). There are three = notes that are driving me nuts. Unless I really smack the note, the = hammer doesn't want to check. They boble so bad that they hit the string = on the rebound.=20 The regulation is just like the other notes, (dip, l.o.,drop, etc.). = Not only is key dip just like its neighbors, but when I increased key = dip, it didn't solve the problem. There is enough damper lever = clearance. I've adjusted the back checks to where the hammer checks = almost back down on the cushion. When I try to make it check earlier, it = catches. I've bent the checks so that the rake is enough to clear the = hammer on the way up, but still catches it on the way down. I've reduced = spring tension to the point of almost no rise, and I've sanded the backs = of the tails. I even changed wippens on one key, but the problem is = still there.=20 What are some other things I should look at?
